Until now, we have been building the business out of Japan, but we believe that Singapore is now becoming the center of Web3 in Asia, and it was inevitable for us to launch our subsidiary there. double will continue to support the Oasys gaming chain as the primary developer, and it made sense for us to set up an office in Singapore, where Oasys is headquartered.

With Ryo Manzoku as the joint representative director and responsible for our blockchain game business, we will work together to accelerate business growth across Asia and globally.
