Metaplanet Inc., a Japanese company listed on the Tokyo Stock Exchange, announced in June 2025 the purchase of a new amount of Bitcoin as part of its strategy to adopt Bitcoin as a reserve asset for its treasury. This decision came amid inflation and fluctuations of the Japanese yen, as the company sees Bitcoin as a safe asset and a hedge against monetary erosion. This move recalls the actions of MicroStrategy in the United States. With this announcement, Metaplanet's stock rose significantly, reflecting increased investor interest in the institutional shift toward digital assets. The company plans additional purchases in the future and is among the first Japanese companies to boldly adopt Bitcoin in its financial strategy.
