double jump.tokyo buys crypto accounting SaaS RIKYU to complete its on-chain stack
What's the deal? Tokyo-based blockchain firm double jump.tokyo (DJT) has agreed to acquire all shares of RIKYUDealroom has a profile for this one. Try Dealroom →, making the crypto and stablecoin accounting SaaS provider a wholly owned subsidiary. The two companies signed a share transfer agreement dated July 10, 2026. Terms were not disclosed.
What does RIKYU do? RIKYU runs a cloud service that automates profit-and-loss calculation, journal entries, and accounting-system integration for crypto and stablecoin holdings. It connects to more than 66 exchanges, blockchains, and accounting tools, and offers three products spanning individuals, businesses, and tax accountants.
What's the endgame? DJT already supports corporate on-chain activity through its business wallet OS, N Suite, and a stablecoin payments business, covering custody and settlement. Adding RIKYU brings accounting into the fold, giving DJT an end-to-end offering from storing on-chain assets to paying and booking them.
Why now? Corporate use of crypto and stablecoins is spreading across payments, treasury, and token businesses. That growth is making on-chain profit-and-loss calculation, valuation, and internal controls a shared headache for companies and the accountants who serve them.
What changes? RIKYU keeps its name, and existing customer contracts are unchanged. It will survive as a DJT subsidiary, with DJT chief operating officer Koki Matsutani set to become representative director after the deal closes. Founders Kenta Takase and Masahisa Abe will stay on as advisers to support product development and handover.
What's next for the product? DJT plans to revise pricing and expand enterprise-focused delivery to reach companies holding crypto and stablecoins. It also wants to extend RIKYU beyond profit-and-loss into an "on-chain log" for stablecoin payment records and audit compliance, and eventually into a service where AI agents handle accounting tasks.
The signal: The deal reflects consolidation in Japan's Web3 back office, bundling wallets, payments, and accounting under one roof. "By joining the double jump.tokyo group, as the only group in Japan with both a wallet service and a crypto accounting system," said RIKYU representative director Kenta Takase, the combined company aims to support corporate on-chain adoption end to end.
