According to TechFlow, Sony and Metaplanet strengthened their control over crypto assets in 2024 to cope with Japan's dwindling currency. Sony acquired digital asset trading service provider Amber Japan for $103 billion and renamed it S.BLOX. Amber Japan operates the "WhaleFin" crypto asset exchange, and the acquisition will provide the application with easier-to-use services and more supported currencies and features.

On the other hand, Metaplanet invested an additional $1.02 million worth of BTC on Monday, becoming the largest corporate holder of BTC in Japan. Metaplanet has also been gradually increasing its BTC holdings since April 2024. The company's basic policy is to hold BTC for the long term to reduce exposure to the yen, and hopes to provide Japanese investors with exposure to crypto assets with a favorable tax structure.

The moves by Sony and Metaplanet point to growing adoption of crypto assets in Japan, which is also facing concerns among officials about currency depreciation. The crypto asset landscape in Japan has undergone significant changes amid a sharp depreciation of the yen and some monetary policies of the Bank of Japan (BOJ).
