Metaplanet Buys Japan's Siiibo Securities, Rebrands Unit to Broaden Bitcoin Treasury Push

Metaplanet said it has acquired Japanese brokerage Siiibo Securities and renamed it Metaplanet Securities Co., Ltd., a move that gives the company licensed access to traditional securities services as it advances its Bitcoin treasury strategy, CoinDesk reported. Siiibo Securities is a licensed first-class financial instruments business operator in Japan and previously provided corporate bond subscription services to individual investors via an online platform. Metaplanet said it will fold the broker into its ecosystem to underpin future securities services and new financial product offerings, combining conventional securities infrastructure with its cryptocurrency-focused direction. CEO Simon Gerovich said the new Metaplanet Securities will operate under "Project Nova," an initiative aimed at bringing Bitcoin-related financial services to Japan's investment market. The report said Metaplanet plans to use Siiibo's regulatory licenses and digital securities infrastructure to develop Bitcoin-linked yield products for Japanese investors, signaling an expansion beyond simply holding Bitcoin on its balance sheet. Metaplanet is also targeting Japan's large pool of household liquidity. The report cited more than 1,190 trillion yen held in cash deposits and low-yield savings products, which the company hopes to channel into higher-yielding assets. Financial terms, settlement details, and the timing for an initial launch of Bitcoin-related products were not disclosed. The report noted that the information available so far is largely based on company statements and overseas media coverage, and described the deal as Metaplanet's first comprehensive acquisition aimed at expanding its Bitcoin treasury initiative.
