BT and KDDI have formed a joint venture to promote global managed services to Japanese multinational companies.

The venture, which will begin operations in August, will employ about 100 people and offer products from both BT, of the UK, and KDDI, the number-two fixed and mobile carrier in Japan.

BT once had a similar arrangement with Japan Telecom, in which it owned a stake, but it largely departed the Japanese market when it sold its shareholding in that company in 2001. The British carrier first entered Japan in 1985.
