Geography and Geology

In the Kasaoka Islands, more than 30 islands are lined up along the fault zone that runs from north-northwest to south-southeast.The topography of each island is also strongly influenced by this fault zone, and the west coast of Kitagi Island and Shiraishi Island is particularly fault scarp.This fault isSeto Inland SeaIs thought to be involved in the formation of[3][4].

Most islands are made of granite.Only Kamishima in the north is exceptionally composed mostly of rhyolite, and only a part of the southeastern end is made of granite.All islands tend to be mountainous and lack flat land, and settlements are formed along the coast and on the mountain surface except for reclaimed land since the early modern period.[6].

Kasaoka IslandsTideAnd the east side isMizushima Nada, The westBingo NadaIs.Especially in the strait about 3km wide between Takashima and ShiraishijimaShiraishi SetoIt is called (Shiraishi Seto), and you can see the phenomenon that the tide goes east and west around Seto at low tide and the tide fills from both sides at high tide.[20].

History and industry

Many archaeological sites from the Paleolithic period to the Jomon period and the Yayoi period have been excavated on the islands of the Kasaoka Islands.In particular, Paleolithic ruins are distributed more mainly on Myoji Island and Takashima than on the mainland.Ruins from the Jomon period onward have been widely found on each island, and the Otomari site on Takashima indicates that there was a large settlement on the island from the Kofun period to the Nara period.On Nishioshima, Kasaoka City, which is on the opposite bank of Yokoshima, from the former coastal areaTsumo KaizukaWas discovered, and 232 human bones from the Jomon period were excavated together.It is the first time in Japan that a large amount of human bones of the same period have been discovered, and it is the second largest number of discoveries in Japan, including subsequent discoveries.As a result, research on burial methods and tooth extraction at that time progressed, and it became extremely important for research on the Stone Age in Japan.There are ritual sites from the Nara period to the Kamakura period on Obi Island.Copper mirrorHas been discovered.These are ancientEnvoy,Envoy,DazaifuIt is considered to be evidence that the officials descending to the island stopped by this island during the voyage to perform a Shinto ritual, and these islands have long been a transportation hub of the Seto Inland Sea as a place for "waiting for the tide and waiting for the wind." Is believed to indicate[7][25][26].

on the other hand,"Japanese calligraphyAnd 'Record of Ancient MattersAs a legend ofEmperor JimmuIn the Kasaoka Islands during the eastern expedition byGyomiyaIt is said that he lived for several years.There is a theory that this Gyomiya was in Kamishima and a theory that it was in Takashima.[27][28].

During the Edo period, reclamation was actively carried out in Kasaoka Bay and the Kasaoka Islands.As a result, some islands near Kasaoka Port were connected to the mainland, and Shiraishi Island and other islands were reclaimed and the urban areas and ports were improved.[7].

In the olden days, people lived mainly in agriculture, centering on upland farming on mountain slopes, especially on each island.cowWas bred.However, as the cultivated land expanded due to the increase in the island's population, there was no land for cattle on each island, which was originally poor in flat land.As a result, dependence on fisheries and water transport increased from the Middle Ages to the early modern period.[29]..The sea area between Kitagi Island and Manabe Island on the main island is a rich fishing ground.[Note 3]Especially in the early modern period, it was known as a sardine producing area.This sardine was mainly made into dried sardines and was heavily used as fertilizer in and around the Kasaoka Islands.[6][17]..In addition, Kitagi Island and Shiraishi Island are also famous as stone producing areas.[17].

When the fishing, water transportation, and stone industries were sluggish due to changes in the economic structure, flower cultivation as a commercial crop prospered temporarily on Manabe Island and other areas.However, it later declined, and the islands, which faced depopulation and aging, began to jointly focus on the tourism industry. In 2005 (Heisei 17), as a part of regional revitalization, the lunch box "Shimaben" was announced as a special product using local seafood.[31][32][33][2]. this isNHKOf the program "Hey, JapanWas jointly developed by Kasaoka City and NPO corporations.[32]..This effort was highly evaluatedMinistry of AgricultureReceived the Minister of Agriculture, Forestry and Fisheries Award in the Village Development Division of the 22 Agriculture, Forestry and Fisheries Festival[34][33][35]..Besides this, in the summerSea bathingCustomers andキャンプIn addition to being crowded with customers, throughout the yearfishingThere are many customers.

Administrative treatment

Since modern timesReclamation of Kasaoka BayIn the Edo period, Yokoshima was connected to the land, and from Showa to Heisei, Katashima and Kamishima were connected to the mainland.For this reason, administrativelyRemote island promotion lawThe target of this is only the islands on the south side of Kamishima, of which the seven inhabited islands are Takashima, Shiraishijima, Kitagijima, Manabejima, Obijima, Kobijima, and Rokushima.[3][37].

In 1957 (Showa 32), it was the first in Okayama Prefecture to be designated by the Remote Island Promotion Law.As a result, roads, ports, and electricity were improved in the Kasaoka Islands.Even after that, the water source on the islands depended on wells, but in 1975 (Showa 50), a water pipe laid on the seabed was constructed, and the water supply became perfect.[6][37].

The Kasaoka Islands are the point of contact between the mainland of Honshu and Shikoku, and at the same timeChinaBingo countryIt is located on the border of Japan, and has come into contact with East and West culture as an important port of call for the Seto Inland Sea route.In the Kasaoka Islands, you can see the characteristics of a mixture of these local cultures.[6].

In terms of accents and dialects, there are differences depending on the location even within the Kasaoka Islands.Okayama dialectHowever, there is an influence of the Shikoku dialect on Mushima and Manabe Island, which are close to Shikoku, and on Kitagi Island, etc.Hiroshima dialect-Bingo valveThe influence of is seen.As an example,Okayama dialectThe characteristic "Kyote" (horrible) is used up to Kitagi Island and Hishima, but on Manabe Island and Mu Island.Sanuki dialect"Otoroshi" is used[3].

Major islands


Yokoshima is an island that was connected to the land by reclamation in the early modern period.According to folklore, this name comes from the fact that what was originally three islets has become a horizontally long island due to reclamation.Kanei yearsIn the pictorial map of (1624-1645), it is depicted as an isolated island "Yokoshima".Enpo2 years (1674) reclamation project connected to the mainland[38].

After that, there were ports in the cove, but these also became land due to the reclamation of Kasaoka Bay from Showa to Heisei.At the southern end, there were small islands such as "Odonsu", which were also integrated by reclamation.[38].


Katashima(Katashima) is located about 3km south of Kasaoka Port and was once the closest island to the mainland in the Kasaoka Islands.It is long from east to west centering on a mountain with an altitude of 58 meters, with a circumference of about 4.5 km and an area of ​​about 0.5 km.2..It was also known as a beach.Reclamation of Kasaoka BayIs now completely continuous[14][39].


Kamishima(Konoshima) is an island located about 3km south of Kasaoka Port.The mainland side of Kamishima is "Uchiura", On the Seto Inland Sea side"SotouraThe village of Uchiura formed a village with the mainland, and the village of Sotoura formed a village with Shiraishi Island.Before Kasaoka Bay was reclaimed and connected to the mainland, it was the second largest island in Okayama prefecture and the largest manned island.[Note 4]was[1][12][40].

It used to be an inconvenient remote island where only rowing boats could berth, but in 1970 (Showa 45), it was with Yokoshima.Konoshima OhashiWas built and connected to the mainland and is no longer a remote island,Reclamation of Kasaoka BayIt became completely continuous in 1990 (Heisei 2).The mainland and between Yokoshima / Odenshu and Kamishima / Kodenshu are close to each other by about 100 meters in width, and are called "Kamishima Suido".The former Kasaoka BayHorseshoe crabHowever, the breeding ground was moved to Kamishima Suido due to the reclamation of the bay.[12][40][1].

Konoshimasotoura has a factory founded in the Meiji era and produces chemical fertilizers.This is Konoshima Kasei, a major fertilizer industry (in 2008)Ube IndustriesKasaoka Port became one of the important economic bases of Kasaoka City as a shipping port for chemical fertilizers.[12][40].

Kamishima Shrine in KamishimaEnki ceremony god name book"Kamishima Shrine" (List of Btsutyuu Shikinai companiesSee).Also,"Manyoshu''Tamabashu''New collection of old and new] Etc., a waka poem about "Kamishima" is recorded, and there is a theory that this is compared to the local area.[12][40].

On the south side of KamishimaTakashimaThe strait between the islands is called Kurotsuchiseto, and there are uninhabited islands such as Sasude Island, Myoji Island, and Inazumi Island.


Takashima(Takashima) is a manned island about 2km south of Kamishima.It is about 12km from Kasaoka Port by sea route.It is accompanied by Sasude Island, Myoji Island, Inazumi Island, Kodaka Island, etc. as genus islands. In 1944 (Showa 19)Scenic spotHas been designated[21][2].

There are many archaeological sites on Takashima, and the old ones date back to the pre-earthenware era.A survey of these sites revealed the appearance of western Japan in the late Jomon period.[21][2][26].

About Takashima and Kamishima,Emperor JimmuThere is a legend that he lived. "Japanese calligraphyAnd 'Record of Ancient Matters』, Emperor Jimmu at the beginning of the eastern expeditionKibi countryCalled "Takashimamiya"GyomiyaIt is said that he lived there for three or eight years.There is a theory that this "Takashima shrine" refers to Takashima and a theory that it refers to Kamishima.[27][28].

Shiraishi Island is located south of Takashima, and the strait between the two islands is called Shiraishi Seto.Shiraishi Seto has uninhabited islands such as Kodaka Island and Kogochi Island[20].

Shiroishi Island

Shiroishi Island(Shiraishijima) is a manned island located 12km south of Kasaoka Port in a straight line and about 16km by sea.Most of the islands are exceptionally flat in the Kasaoka Islands, where flat land is scarce, but the flat land in the central part of the island was originally a cove and was reclaimed as a reclamation project during the Edo period.[2][20][36][41].

Shiraishi Island is located in the center of the Kasaoka Islands, not only the tide boundary between Mizushima Nada in the east and Bingo Nada in the west, but also the position that divides the entire Seto Inland Sea into east and west.At high tide, in the eastKitan Strait,Naruto StraitThe seawater (climbing tide) that came in from and the westToyo Strait-Kanmon StraitThe climbing tide from the island collides near Shiraishi Island.On the contrary, when the tide is low, the tide goes east and west with Shiraishi Island as the boundary.For this reason, Shiraishi Island has long been known as an important port in the Seto Inland Sea.In the early modern period, the central cove of the island was reclaimed and a large port was constructed, which was frequently used as a substitute route for Saigoku daimyo.Visited Japan in the late Edo periodEngelbert KempelIn "Edo Sanfu Travel Diary" (Genroku 4th year), "a convenient anchoring place that can never be expected in the future voyage"[20][36][41].

In 1943 (Showa 18), the nationalScenic spotHas been designated.In the center of the island, there is a granite with a height of about 10 meters.Shiraishi Island Armor RockIt has become a national natural monument.A Bon festival dance called "Shiraishi Odori", which is said to have started to mourn the dead of the Genpei War, has been transmitted to the island and has become an important intangible folk cultural property of the country.[20][36][41].

Kitagi Island

Kitagi Island(Kitagishima) is 14km south of Kasaoka Port in a straight line, and about 25km by sea.It is the largest island in the Kasaoka Islands and is considered to be the main island.The islands tend to be mountainous, including Mt. Buckli at an altitude of 225m, Mt. Tongiri (179.6m), Mt. Takayama (177.9m), Mt. Akiha (160m), and Mt. Yawata (141.7m).The flat land is scarce, and the main settlements are formed in "Toyoura" and "Kinburo" on the north bank, "Oura" on the east bank, and "Maruiwa" on the south bank.[42][43][2].

The granite produced on Kitagi Island is "Kitaki stoneIs calledInada stoneTogether with "GraniteDouble wall[44]It is said that.Kitagi stoneOsaka CastleIn addition to being used on a large scale at stone walls and gates inPrincess MunekoCemetery),Hideyoshi ToyotomiCemetery, KyotoGojo Ohashi,Meiji JinguBridge,Yasukuni ShrineTorii,Ise ShrineStone lantern,Yakushiji TempleWest Tower,Bank of Japan OfMain store old building,MitsukoshiUsed in the main store etc.[45][46][17][42][43][47].

Around Shiraishi Island and Kitagi Island, there are uninhabited small islands called Vertical Island and Yokobe Island.The islands of the Kasaoka Islands used to be buried, but they were limited to the islanders.Many workers from outside the island came to the island to cut out stones, and if they died in an accident, they were cremated on the vertical and horizontal islands.[48].


Obishima(Obishima) andKobi IslandAs a general term for (Kobishima)TobishimaIt's called (Hishima).The straight line distance from Kasaoka Port is about 18km, and the actual route is about 25km via Kitagi Island.These two manned islands are lined up at a distance of about 2 meters, and are famous for the sandbars that appear from Obi Island to Kobi Island at low tide.At the end of this sandbar is from the 900th century to the Kamakura periodRitual ruins(Obishima Site), And domestic Sancai (Nara Sansai), Tang dynasty bronze mirrors, and twelve dynasties have been discovered.The sandbar has become smaller in recent years, and the cause of the shrinkage of the sandbar is not clear, but it is speculated that it is related to the collection of sand on the seabed in the nearby sea.[18][49][50].

In the olden days, it was treated as a genus island of Kamishima, but in the early modern period, fishermen moved to Obijima and Kobishima and settled there, and it was treated as a branch island of Manabe Island.In the Showa period, many islanders began to work as sailors, and the population was usually about 400, but the population reached 800 only during the Bon Festival and New Year when the migrants returned home.[51][50].

Manabe Island

Manabe Island(Manabeshima) is a manned island located 18km south of Kasaoka Port and about 30km by sea.As a genus islandMushima, Oshima, Tokoshima, Tokoshima, Tokoshima, etc. 2.5km eastSanagishima(Shiozawa Islands).The island is long from east to west, with mountains at an altitude of 120m on both sides and almost no flat land.There is a cove on the north side of the island and a harbor is built[16][29][52].

It is said that it was the base of Mr. Manabe (Mr. Manabe) who arrived at the Heike clan during the Genpei War, and there is the ruins of the castle.In the early Edo periodKobori EnshuRuled, but for two years from 1617 (Genna 3)Bitchu Matsuyama Domain, From 1619 (Genna 5)Bingo Fukuyama Domain, Became a shogunate territory from 1968 (Genroku 11)[16][29].

It has prospered in the fishing industry since ancient times, and there is a record that during the Edo period, live fish were delivered directly from Manabe Island to the Edo market.The streets and buildings still retain the atmosphere of an old fishing village in the Seto Inland Sea.Prefecture's hometown villageIs specified in.Taking advantage of these streets, the movie "Setouchi Boy Baseball TeamIt became the location of[16][52][53].

Because there was no frost in 1947 (Showa 22)CamelliaCultivation was commercialized, and at its peak it became known nationwide as the "Flower Island" with a cultivation area of ​​30 hectares.However, it declined due to continuous cropping obstacles and changes in the market.[16][29][54].


Oshima is a general term for "Oshima" and "Oshima" in the north of Manabe Island.It is also called "Manabeshima" to distinguish it from the islands here and there.Oshima and Mae Oshima are close to each other at a distance of about 100m, and the islands are connected by a thin rocky area.Currently, all of them are uninhabited islands, but Oshima used to be cultivated.Mae Oshima has a giant tree estimated to be 400 years old.[Note 5]"(Machilus thunbergiiIs designated as a natural monument[16][55][29].


Mushima(Mushima) is a manned island and is the southernmost tip of Okayama prefecture.It is the farthest from Kasaoka Port in the Kasaoka Islands, about 23 km in a straight line, and about 33 km on the route.It is also the southernmost tip of Okayama prefecture.About 4.5km south of mainland ShikokuShonai PeninsulaThe area between Mushima and the Sonai Peninsula has long been known as one of the difficult places where the tide flows quickly even on the Seto Inland Sea route.Therefore, it is also the first place in Okayama prefecture where a lighthouse was installed.[56][57].

Before the war, it was handled as a "live boat" that transports live fish.Awaji IslandIt was the best in Japan, but it became obsolete when the motorization of ships became widespread after the war.[56].Yokomizo Masashiof"Gokumon Island』(Kaneda Kosuke Series), Known as the stage1977 movie adaptationThen, shooting is actually done in Mushima[58][59][57].


Due to its location, the Kasaoka Islands have been one of the most important ports on the Seto Inland Sea route since ancient times, and there have been many ports of call as bases for movement and the fishing industry.However, recent vessels that have become larger cannot enter the islands of the Kasaoka Islands.The south of Mushima has a tide boundary with the Nada, and the tide is fast, making it a place with a high risk of marine accidents.For this reason, Mushima has a lighthouse and a signal station.[57].

Currently, to each manned island in the Kasaoka IslandsKasaoka PortIn addition to regular sea routes, sea taxis are also available.However, there are concerns that the function as a connecting port will decline due to the deterioration of Kasaoka Port and the lack of parking lots.The ports on each island are also small, shared by passenger ships, fishing boats, fishing boats, and pleasure boats, and the transportation function is not high.[2][60].

Mountain worship

Mt. Ishizuchi is a famous mountain whose mountains have not been influenced by Buddhism since ancient times, and the ancient name of Mt. Ishizuchi is Iwatsuchi, which means elder in the South Sea language. , It is called Iwatsuchi in the sense that it is the head of a rocky mountain, and it comes from the open rock near the summit.[5].Mountain worshipIt is said to be a mountain ofNara periodKnown as a training dojo,Small angle,KukaiIs said to have practicedMountain buddhism,Study roadHas developed and as a base of faithIshizuchi Shrine,Maejinji Temple,Gokurakuji Temple,Yokomine TempleThere is. (The fulfillment of Ishizuchi Shrine Nakamiya was called permanent residence before the separation of Shinto and Buddhism in the early Meiji era.)

The ancient Mt. IshizuchiMt. Sasagamine,KamegamoriAnd there is a theory that Mt. Gongenyama was the center of Ishizuchi worship, or that the current two sacred areas of Mt. Ishizuchi and Mt. Sasagamine are assumed.[1][6]. (NiihamaBased on the fact that Mt. Ishizuchi in the Nara period pointed to Mt. Sasagamine at Shoboji Temple, Mt. Sasagamine is still being visited every July as a betto of Ishizuchi Gongen. )

In 657 as a tradition of KaisanPerformerAnd the Hosen who served it is Mt. Ryuo (KamegamoriAt an altitude of 840 m on the hillside, he founded Tianhe Temple with a sense of the training of Sueishi Dozoou Gongen.Yokomineji Temple was opened by Ishisen, the chief priest of Hoanji Temple (Komatsu, Saijo City, Ehime Prefecture, founded in the Asuka period), and the predecessor of Maegamiji Temple was built on the hillside of the mountain.After that, he was also a disciple of Ishisen and trained in Kurokawadani.Kamisen Bosatsu(From Kamino-gun, Iyo Province) leads to Kaisan in honor of Ishizuchi Zao Daigongen. In 737, Ishido Zao Gongen was enshrined at the height of Kamegamori and was called a palace, and in 753 Yoshimoto solicited Kumano Gongen.The mountain is called Mt. Ishizuchi, and Tianhe Temple prospered as a special case.Then, in 828, Kamegamori moved Mt. Ishizuchi to the current Mt. Ishizuchi.MitsudaMoved by (from Kazahaya-gun, Iyo Province) and became known as Mt. Ishizuchi[7].

Heian periodIn the first halfGod Buddha practiceIs said to have been done, peculiar to mountain worshipKongo Zao GongenAnd was enshrined.Then, when Emperor Kanmu (782-805) fulfilled his prayer for healing his illness and the gratitude for Heiankyo, he ordered the Kokushi to build the Shichido Garan as a permanent residence and made it the title of "Golden Temple". Was given.TenshoIn the yearToshinao Kono, Is the company territory,1610 (Keicho15 years)Hideyori ToyotomiDonated the shrine to Maejinji.KanbunIn the yearKomatsu DomainmainMr. Ichiyanagi,Saijo clanmainMatsudairaThe shrine was improved by the devotion of[8][9].

Edo PeriodIn the early days, as the number of believers increased, Maejinji set up a branch office at the foot of the temple, and then the permanent main temple was called Okuzenjinji, and the branch office at the foot was called Satozenjinji.After that, the main temple function moved to the village.And over the estate of Betto and OkuzenjinjiSaijo clanA dispute arose between Maejinji Temple in the territory and Yokomineji Temple in the Komatsu Domain.From ancient times, Maejinji used to be the exclusive name for Ishizuchiyama Zao Gongen Betto.1729 (KyohoIt is said that Yokomineji used the seal of "Ishizuchiyama Zao Gongen Betto Yokomineji" in 14), and both sides said that it was the beginning.京都 OfImperial PalaceI came to file a complaint.Therefore, the estate is the Sensokuyama village of the Komatsu domain, the management right and the exclusive name of "Ishizuchiyama Zao Gongen Betsuto" are changed to Maejinji, Okuzenjinji is renamed to Permanent Shrine, and Yokomineji is "Fukoyama Ishizuchisha".[Annotation 1]It was decided to call it "Betto"[1].

1871 (Meiji4 years)Divine Buddha separationAs a result, Ishigane Zao Gongen became Kuebiko Ishido, and all the temples of Maejinji became Ishitetsu Shrine, Maejinji became an abandoned temple, and Yokomineji became Yokominesha.Both temples were reconstructed soon afterwardsShingon sectI will belong to. In 1902 (Meiji 35), it was decided to change from Ishizuchi Shrine to Ishizuchi Shrine.[10], Mt. Ishizuchi Komei (Mt. Ishizuchi), Mt. Ishizuchi.After the middle of the Meiji era, Ishizuchi Shrine, Maejinji Temple, and Yokomineji Temple attracted even more believers.

Every year,May 7から10 daysIn the meantime, "Oyama opening"ShintoismWas carried out, and many believersWorshipVisit for mountaineering.During the period of mountain opening from ancient timesFemale ProhibitionIt has been said, but now only July 7stFemale ProhibitionIt became.On the day of the event, women cannot climb to the summit until they reach the office or reach the Tsuchiya Harukaden.[11].


The top of Mt. Ishizuchi usually refers to Mt. Tengudake, but due to the rocky area from Mt. Misen to Mt. Tengudake and the lack of space for many people to stay in Mt. Tengudake, just before Mt. Tengudake. There are many climbers up to Mt. Misen (about 200m before).On Mt. Misen, there is a mountaintop hut in addition to the seat of Ishizuchi Shrine.

There are three chains up to Mt. Misen, from the bottom, "one chain" (3 meters), "two chains" (33 meters), and finally "three chains" (65 meters).DetourThere is also. In front of the "first chain", there is a "trial chain" (1,592 meters) over the rocky peak of Maesagamori (74 m), which is the steepest slope.To MisenlockIs said to have been hung since the early modern period1779 (Ernst & Young8 years), the chain broke, the next1780 "Ishizuchi Mt. Misen Chain Muscle Nokaku", which is a record that the chain was changed in (Anei 9), is left in the old record of Maejinji Temple.From the summitSeto Inland Sea,andTosa Bay, On a clear dayMt.

Directly below Mt. Tengudake, there is a steep and overhanging north wall, which provides a rock climbing field that can be said to be the best in Shikoku.Sawanobori and Minamizawa on the southwestern slope are known as Sawanobori routes.In addition, it should be notedDogamoriからNinomoriThere is also a vertical route on the main line of the Ishizuchi Mountains that leads to Mt.
