BT is seeking to build its own telecomms infrastructure in Japan.
The UK telco is applying for a type one carrier licence through BT Network Information Service (BT NIS), its joint venture with Japanese telco Marubeni.
BT already holds a special type two licence which allows it to resell voice, data and Internet services from type one carriers.
Japan has been a strong focus for BT ever since the UK telco announced its failed attempt to merge with MCI. During the time BT was engaged to MCI, BT was also wooing NTT, Japan's incumbent. Without MCI, BT is now thought to be a less attractive prospective partner for NTT.
BT NIS was formed last March. It aims to achieve revenues of $100 million in its first year, and already numbers 10,000 customers, 300 of which are among Japan's top 1,000.
BT's chief executive, Peter Bonfield, said: "We are moving quickly to bring benefits of liberalisation of the Japanese market to our customers. This latest move provides strong evidence of our growing commitment to this market."
