Metaplanet Inc. agreed with Metaplanet Securities Inc., JPYC Inc., and Progmat, Inc. to commence a joint study in the digital credit domain utilizing Bitcoin, stablecoins, and security tokens on July 10, 2026.
Key Takeaways
- Metaplanet, Metaplanet Securities, JPYC, and Progmat agreed on July 10, 2026 to jointly study bitcoin-backed digital credit, security tokens, and stablecoin settlement.
- Siiibo Securities Inc. is scheduled to change its trade name to Metaplanet Securities Inc., effective July 13, 2026, tying the brokerage formally to Metaplanet’s bitcoin strategy.
- Under Project NOVA, Metaplanet treats Bitcoin not as a passive treasury holding but as productive collateral on the balance sheet, a step beyond the buy-and-hold Bitcoin Treasury model.
- The study names Japan’s Companies Act dividend and record date systems, shareholder registry administration, and book-entry infrastructure as the actual barrier to round the clock onchain bond settlement.
- The four parties stressed that nothing has been determined on issuance timing, terms, yield, product details, distribution methods, or the form of collaboration, and the notice is not a solicitation of any financial instrument.
What Happened?
Metaplanet, listed on the Tokyo Stock Exchange (TSE), published its joint study notice, in which Metaplanet Inc., Metaplanet Securities Inc., JPYC Inc., and Progmat, Inc. agreed to commence the joint study, according to Metaplanet. Progmat issued a matching notice the same day that confirms the same four-party arrangement signals across Japan’s listed bitcoin-treasury sector.
The study spans the digital credit domain broadly, from digital corporate bonds to other credit instruments. Each company brings a distinct piece: Metaplanet and Metaplanet Securities handle product design, structuring, and investor distribution; JPYC is exploring stablecoin issuance and redemption for the payment, distribution, and redemption of bonds; and Progmat supplies regulated infrastructure for security-token issuance, rights transfer, and holder management, connected to stablecoin settlement. Metaplanet Securities Inc. is the post-rename identity of Siiibo Securities Inc., joining the study days before its new name takes effect.
Today Metaplanet, Metaplanet Securities, JPYC, and Progmat announced a joint study in digital credit, combining Bitcoin, stablecoin settlement, and security token infrastructure.

From Passive Treasury to Productive Collateral
Metaplanet’s notice states it plainly: the Company treats Bitcoin not as a passive treasury holding but as productive collateral on the balance sheet. That single line is the study’s real substance.
Under Project NOVA, Metaplanet combines Bitcoin-linked financial products, credit products, digital securities, and stablecoin settlement, aiming to deliver new yield products and capital market access to retail and institutional investors in Japan.
That framing separates Metaplanet from the buy-and-hold treasury cohort: Bitcoin here backs and enhances a credit instrument instead of merely appreciating on the balance sheet.
Japan’s Companies Act Is the Real Bottleneck
Bitcoin-backed digital credit, the notice states, could evolve into instruments traded and settled globally on a 24/7/365 basis, with interest and distributions accruing daily according to the holding period. Daily-accrual instruments and supporting market infrastructure already exist in the United States as a reference point. In Japan, the dividend and record-date systems under the Companies Act, shareholder registry administration, and book-entry infrastructure constrain such designs.
The obstacle the study names is administrative law built for paper era shareholder registries: dividend cycles and record date rules that were never designed for daily, holder-level settlement. JPYC (Japan’s regulated yen-pegged stablecoin issuer) and Progmat (a security-token infrastructure venture) exist specifically to bridge that gap between conventional capital-markets plumbing and on-chain settlement.
Implications for Bitcoin Treasury Companies
The mechanics resemble a regulated cousin of decentralized finance. JPYC would carry the cash leg as a yen-denominated stablecoin, Progmat would carry the rights and holder-management layer for the security tokens, and Metaplanet’s Bitcoin would sit behind the credit as collateral. It is closer to the settlement logic of decentralized finance than to a conventional corporate bond desk.
The template on offer is a second business line. A treasury company that turns Bitcoin into credit-backing collateral is not limited to buying more coins as its only lever. Nothing here is close to that yet. The four companies have committed only to studying the idea, subject to regulatory consultation and their own internal approvals.
CoinLaw’s Takeaway
This is a memorandum stage study, not a product, and the release says so directly. No decision has been made on issuance timing, terms, yield, or structure, and the notice is not an offer of any financial instrument. What makes it worth tracking regardless is the specificity of the obstacle Metaplanet named: a decades old shareholder registry system built around fixed record dates, not an abstract reference to “regulatory uncertainty.“
The more durable signal is Bitcoin’s changing job description on a listed balance sheet. An asset backing credit does different work than one that only appreciates, and that is a different business model for a bitcoin treasury company to run. Whether Metaplanet, JPYC, and Progmat can actually clear Japan’s securities-law constraints, rather than simply naming them, is the question the next disclosure will have to answer.
