Metaplanet buys Siiibo Securities to expand Bitcoin product plans in Japan

Metaplanet has agreed to buy Japanese securities firm Siiibo Securities in a deal valued at about $13 million, marking a further step in its effort to build out a Bitcoin-focused financial business in Japan, according to reports from Decrypt and CoinDesk.

The acquisition gives Metaplanet access to a regulated securities platform that it can use to develop Bitcoin-linked investment products, including plans described by one report as Bitcoin yield products. The move appears designed to help the company extend its role beyond direct Bitcoin exposure and into a broader set of financial offerings tied to the cryptocurrency.

According to Decrypt, the acquisition also reflects a strategic attempt to position Metaplanet for Japan’s shifting macroeconomic backdrop. The report said the Siiibo Securities deal could allow the company to tap into a large pool of household savings as the country moves from a long period of deflation toward inflation. Decrypt cited the size of that household savings pool at $7.4 trillion.

CoinDesk reported that the purchase is intended to accelerate Metaplanet’s plans for a Bitcoin financial ecosystem. By acquiring a securities business already operating within the regulated market structure, Metaplanet gains a platform from which it can work on products linked to Bitcoin without having to build every piece from the ground up. The report put the deal value at approximately $13.1 million.

The transaction comes as companies tied to digital assets continue to look for ways to connect crypto-native products with traditional financial infrastructure. In this case, the acquisition of a securities firm suggests that Metaplanet is seeking a more formal route into investment products rather than relying only on corporate treasury-style Bitcoin holdings or direct market participation. The firm’s approach appears focused on creating a bridge between regulated finance and Bitcoin-based offerings.

The sources did not provide details on the structure of the transaction, the closing timetable, or the specific product lineup Metaplanet intends to launch. They also did not identify any immediate market reaction. Even so, the deal underscores how some market participants are trying to adapt to changes in Japan’s economic environment and the growing role that Bitcoin-linked products may play in that shift. By securing a licensed securities platform, Metaplanet has taken a step that could support future distribution of crypto-related investment products within Japan’s regulated financial system.
