TLDR:

• Quant brings proven technology from Bank of England and European Central Bank pilot programs to Japan.
• Dentsu Soken’s StreamR system compatibility with BOJ-NET positions partnership for institutional adoption.

• Industry executives identify 2026 as pivotal year for stablecoin evolution and digital money implementation. 

Quant and Dentsu Soken have formed a strategic partnership to advance Japan’s digital money infrastructure. 

The collaboration will focus on tokenised deposits, institutional stablecoins, and programmable settlement systems for Japanese financial institutions. 

This partnership combines Quant’s proven interbank settlement technology with Dentsu Soken’s extensive experience in Japan’s payment systems. 

The move signals Japan’s shift from pilot projects to production-ready digital money solutions.

Building Programmable Settlement Infrastructure for Japanese Banks

Quant brings established credentials from multiple regulated pilot programs to this partnership. The company has worked with the Bank of England and Bank for International Settlements on Project Rosalind. 

Additionally, Quant participated in trials with the European Central Bank and the UK Regulated Liability Network. 

The Great Britain Tokenised Deposit project also utilized Quant’s programmable settlement and orchestration infrastructure.

Dentsu Soken contributes deep technical expertise in Japan’s financial ecosystem to the collaboration. The company has developed mission-critical payment and settlement systems for leading Japanese banks. 

Its StreamR settlement management system operates with BOJNET, the Bank of Japan’s Real-Time Gross Settlement system. 

Dentsu Soken has also built global core banking platforms, internet banking systems, and cash management solutions.

The partnership will address four key areas identified through industry and policy discussions. Programmable settlement will coordinate money and asset flows across legacy systems and new tokenised rails. 

Banks will implement tokenised deposit logic including conditional payments and synchronisation with existing ledgers.

Treasury automation will help institutions optimise intraday liquidity and reduce manual reconciliation processes. 

The companies will also deliver interoperability solutions using Quant’s ISO 20022-native architecture tailored for Japanese requirements.

Quant announced the partnership on social media, noting that digital money has moved beyond theory. The company stated Japan is transitioning from pilot to production with regulatory experience and implementation expertise. 

Both firms will execute a joint go-to-market plan combining Dentsu Soken’s implementation teams with Quant’s settlement technology.

Japan’s Financial Sector Prepares for Digital Money Evolution

Japan’s tokenised financial ecosystem has developed rapidly as institutions evaluate digital money frameworks. 

Banks and payment networks are examining how these systems fit within existing settlement and compliance structures. 

The partnership addresses this evolution by merging local implementation capabilities with proven programmable settlement infrastructure.

According to Gilbert Verdian, Founder and CEO of Quant, Japan stands at an important turning point. “Banks are preparing for tokenised deposits, new forms of digital money and more interoperable settlement systems,” Verdian explained. 

He added that partnering with Dentsu Soken enables support for Japan’s transition with technology that is proven and compliant.

Lenna Russ, Chief Commercial Officer at Quant, noted Japan’s emergence as a forward-looking market for tokenised deposits.

“Over recent months we have built strong alignment with Dentsu Soken on how institutions can introduce these capabilities safely,” Russ stated. She expressed excitement about supporting the next phase of this transition together with their partner.

Chie Ito, Executive Officer at Dentsu Soken, expressed appreciation for the collaboration with Quant. “We are honoured to collaborate with Quant; an organisation with a proven track record through projects such as the UK’s GBTD initiative,” Ito remarked. 

She identified 2026 as a pivotal moment for stablecoin evolution and committed to supporting safe implementation of programmable payments.
