Chinese smartphone vendor Oppo said its 5G smartphones will officially be sold from Japan's leading telecom operators - KDDI and SoftBank - in the Japanese market.

The move is seen by the company as a milestone for its 5G expansion into the Japanese market. It signifies Oppo's first steps into Japan's mainstream market, where telecom carriers play an important part in selling handsets.

Starting Wednesday, Oppo's first 5G flagship, Find X2 Pro, will be sold from KDDI. And starting July 31, Oppo's Reno3 5G will be sold from SoftBank.

Alen Wu, vice-president of Oppo, said: "Japan has always been an important market for Oppo. For two years, we have continued to localize our products and marketing to meet Japanese consumers and carriers' high standards and unique needs. In the future, Oppo plans to work closely with leading local partners like KDDI and SoftBank and continue to introduce leading 5G products, technologies, and services to more Japanese consumers."
