Sony Group has acquired Amber Japan, marking its official entry into the crypto exchange market. Amber Japan, formerly DeCurret, is the Japanese subsidiary of Amber Group and offers regulated digital asset trading services. This acquisition is part of Sony's strategy to diversify its portfolio, which includes ventures into NFTs and blockchain technology in gaming. Amber Group had previously faced financial troubles due to exposure to the collapsed crypto exchange FTX and raised $300 million in a Series C round to stabilize its operations.
