Transition of investment company

Vodafone's acquisition of Jayphone

Japan Telecom (JT), the parent company of J-Fon, was liable for a debt of 8000 billion yen due to capital investment that the company had guaranteed debt due to the withdrawal of capital from Nissan Motor Co., Ltd., a co-sponsor of digital tu-car companies. It was refraining from capital investment for W-CDMA. In 1999, it raised funds by accepting 15% each from the former AT & T in the United States and BT in the United Kingdom. Was the parent company of JTJRSince each company held 33.8% of JT shares, management rights were secured, but for JR who was focusing on debt reduction from the JNR era, JT was only a costly company, and JT became JR Since we decided to introduce foreign capital without notice, our relationship with JR was getting worse.

In 1999, US Airtouch Communications, which had a direct investment in the operating company J-phone, was acquired by Vodafone Group (VFG) in the UK (in 2014Verizon wirelessVFG participated in the management (the president of J-Fon Hokkaido was from Air Touch. Thompson later became Senior Managing Executive Officer and General Manager of Technology Headquarters). VFG aims to enter the Japanese mobile phone market with the acquisition of J-Fon, and in 2001 AT & T / BT andJR Tokai-JR West JapanPurchased the shares of Japan Telecom that were released. TOB implementation in September of the same yearJR EastAlso acquired Japan Telecom shares and raised its stake to 66.73%, making it a subsidiary of VFG.

Immediately after making Japan Telecom a subsidiary, the brand was quickly launched in October 2001.VodafoneDecided to move to.J-PHONEToVodafoneThe dual logo, which is also used, was adopted to improve brand recognition. In addition, in order to further raise awareness, liking, and preference, we forced to change the domain of the email address, but this caused a great deal of disagreement and caused confusion. For this reason, even if it becomes SoftBank, unless you change the e-mail address of the assigned Vodafone domain in the initial state, you can receive it even if you send e-mail to the e-mail address using the domain of the J-phone era. There is.

In the Jayphone era, the net number of contracts increased steadily by developing services such as copy mail, and at the end of March 2002, au, which had been deciding a strategy, overtook by the overall share, the total number of subscribers was only one month Was also second place[29].. But with JapanEuropeDue to the "convergence terminal" strategy of releasing terminals with the same specifications as above, we were unable to provide the service that became a hot topic following "Sha-mail". as a result,QualcommWith the evolution of chipsRinging songOther carriers such as au who have released services such as "will lose their share.

In addition, many of the measures are backfires, such as the fact that after 10 "promises from Vodafone," it became a breach, the price was revised for most users, and the attractiveness was reduced by narrowing down the terminal procurement. Came out to.

For this reason, VFG was forced to reassess its Japanese business, and former NTT DoCoMo Vice PresidentShiro TsudaTheHead huntingOr took some action, such as increasing capital investment. However, due to pressure from shareholders to secure profits, failure of Verizon to become a wholly owned subsidiary in the United States, concentration of capital in growth markets, etc. Decided to withdraw. Thus the history of Vodafone in Japan came to an end.

Capital structure before the acquisition of Vodafone

Prior to the integration of the Japon regional companies in East Japan, Tokai, and West Japan (February 2001), the investment ratio of Jayphone Co., Ltd. was as follows.

  • Japan Telecom Co., Ltd.-54%
The legal personality goes back to railway communication, and after the acquisition of VFG, Japan Telecom Holdings → Vodafone Holdings → Vodafone → Softbank Mobile → Softbank.
