Japan\'s Siiibo Securities will change its name to Metaplanet Securities

Siiibo Securities will officially change its name to Metaplanet Securities on July 13, after Metaplanet completed the acquisition for 2.1 billion yen. The licensed broker will become the group\'s platform for bitcoin-related investment products and regulated financial services. The move advances Metaplanet\'s \"Project Nova\", a strategy that aims to leverage Japan\'s 1190 trillion yen (US$7.4 trillion) low-yield savings market using bitcoin-driven financial instruments.

Japanese brokerage firm Siiibo Securities will officially change its name to Metaplanet Securities Co., Ltd. on July 13. This marks the latest step in Bitcoin depository company Metaplanet\'s strategy of building a regulated Bitcoin financial ecosystem in Japan. The news was confirmed by Siiibo Securities and Metaplanet CEO Simon Gerovich on Platform X. Gerovich welcomed Siiibo Securities to join the Metaplanet Group. The name change follows Metaplanet\'s agreement to acquire the licensed securities company for approximately 2.1 billion yen (approximately US$13.1 million), which is expected to close on July 13.

Gerovich posted on platform X today: \"We welcome all colleagues from Siiibo Securities to join the Metaplanet Group. On July 13, we will embark on a new journey under the name of \'Metaplanet Securities\'. Together, we will bring unprecedented income-generating products to investors across Japan. This is the next step in building a financial ecosystem with Bitcoin at its core.\"

What is Metaplanet\'s new subsidiary Siiibo Securities?

Siiibo Securities said that after joining the Metaplanet Group, it will accelerate various measures to meet investors \'growing demand for income-based products. Founded in 2019, Siiibo operates an online platform that connects companies and investors seeking to issue private equity firm bonds. The company currently supports approximately 40 corporate issuers and has facilitated more than 100 bond issues. In addition, Siiibo holds a Japanese Class I financial instruments business license, allowing it to provide securities products under Japan\'s regulatory framework.

Siiibo CEO talks about becoming Metaplanet Securities

After the acquisition was completed, Siiibo CEO said that the company plans to use Metaplanet\'s expertise in Bitcoin treasury management to expand its business beyond traditional risky debt products. The brokerage aims to create a \"BTC× Finance\" platform. Siiibo Securities will launch bitcoin-based investment products and other innovative income-based tools tailored specifically for Japanese investors. The acquisition also gives Metaplanet regulatory capabilities it previously lacked, allowing it to directly build and distribute bitcoin-related securities through its own licensed brokers.

What exactly is Metaplanet\'s \"Project Nova\" strategy?

The name change of Siiibo Securities is a key milestone in Project Nova. The plan is Metaplanet\'s long-term strategy to transform the company from one of the world\'s largest corporate Bitcoin holders to a native Bitcoin financial platform. The company recently purchased Bitcoin for the first time after April, adding 2823 BTC. Today, with 40177 BTC holdings on its balance sheet, Metaplanet is committed to initiating, distributing and managing bitcoin-backed financial products. As of June 2026, the company is Asia\'s largest holder of corporate Bitcoin and ranked third in the world.

According to its shareholder documents, Metaplanet\'s \"Project Nova\" strategy targets Japan\'s approximately 1190 trillion yen (approximately US$7.4 trillion) pool of low-yield household assets, including cash deposits, government bonds, money market funds and corporate bonds. Through the soon-to-be-established regulated entities such as Metaplane Securities, the company plans to provide bitcoin-related revenue products and targets areas such as asset management services, tokenized securities, digital credit instruments, lending, custody, and stablecoin payment infrastructure. These initiatives aim to create new sources of revenue beyond simply holding Bitcoin, similar to the ongoing business expansion of other digital asset custodians.

Therefore, the establishment of Metaplanet Securities on July 13 marked the official launch of Metaplanet\'s larger and more ambitious \"Rising Star Project.\"
