Capital Layer expands stablecoin settlement corridor to Japan with Green Monster Inc at WebX Tokyo

At WebX Tokyo on July 13–14, Capital Layer used the conference to push a simple pitch to Japanese and regional institutions: help build a cross-border stablecoin settlement corridor across Asia. For high-risk PSPs and banks, the useful part is not the stage language; it is the combination of a Japan–Taiwan institutional settlement stack, a listed local partner, and a live bank-side proof of concept in Taiwan.

1. Capital Layer, which describes itself as a digital asset orchestration layer for Asia, announced a partnership with Tokyo-listed Green Monster Inc. (TSE Growth: 157A) to build institutional stablecoin settlement infrastructure across Japan and Taiwan. Green Monster will support the Japan-side development, while its consumer-fintech and financial-education business adds more than 10 million app downloads to the mix.
2. The partnership is not staying inside Japan. Green Monster has also established a subsidiary in Hong Kong, which extends the structure’s reach across Asia and gives the project a broader regional footprint than a single-market pilot usually has.
3. The announcement followed a week of activity in Taiwan. Capital Layer co-hosted the Stablecoin Summit at the 2026 Taiwan VC & PE Summit in Taipei on July 8, described as Taiwan’s first public event dedicated to stablecoins after the passage of its Virtual Asset Service Act on June 30, 2026. Regulators, banks, and infrastructure builders were in the same room, which is the part that usually matters when a settlement model is supposed to move from slideware to compliance sign-off.
4. At that summit, Capital Layer and Taiwanese bank O-Bank (2897-TW) presented a cross-border settlement workflow in a live proof-of-concept (PoC) demonstration. The test ran in a fully simulated environment with no real funds, and showed a yen-stablecoin payment from a Japanese institution being received by O-Bank and settled into fiat inside the bank’s existing risk and compliance controls, with governance and an audit-ready record.
5. The scenario modeled JPYSC, a yen-pegged stablecoin issued by SBI Shinsei Trust & Banking and co-developed by Startale Group and SBI Holdings. Because JPYSC has not yet officially launched, the simulation was built and run by Capital Layer on Digital Asset Stacks (DAS), its bank-facing settlement platform; real JPYSC would be used only in a future production deployment once it is fully launched.

The timing is not accidental. The stablecoin market now exceeds US$300 billion in circulation, and Standard Chartered projects it could reach roughly US$2 trillion by 2028. Japan is already one of the more advanced regulated stablecoin markets, with its three largest banks — MUFG, SMBC, and Mizuho — reported to be working toward yen-stablecoin issuance under a regulatory framework shaped by recent Payment Services Act reforms.
