Three Japanese Banks to Test Stablecoins Complied with Domestic Law on ‘Japan Open Chain’

G.U.Technologies Inc. (CEO: Daimei Inaba, CTO: Hidekazu Kondo), developing and offering web3 business infrastructure, has announced that it has been testing the use of issuing stablecoin that complied with Japanese law on public blockchain “Japan Open Chain”, fully Ethereum compatible chain operated by Japanese companies.

Banks that will participate include the Tokyo Kiraboshi Financial Group, Minna no Bank, and The Shikoku Bank. The test will focus on the issuance and remittance of stablecoin-type e-money on Japan Open Chain using our stablecoin issuance/management system.
We are committed to implement the stablecoin system that meets the legal requirements as well as promoting business-to-business remittance and the general use of stablecoin.    


■ Contents of the Test

There are various types of stablecoin issued around the world. The problem, however, is that some of those are actually algorithm types in which the value fluctuates or false stablecoin with no backed assets.

This test will use the stablecoin issuance system for financial institutions developed by G.U. Technologies, to verify that each bank can issue its own stable coins on the Japan Open Chain, a fully Ethereum-compatible public blockchain that is backed and compliant with Japan's new fund settlement laws.

Our goal is to issue the legally-supported stablecoin in cooperation with the testing and production environment of the banking system.


■ Use Cases of Stablecoin and the Benefits of its Use

Currently, there are approximately 20 trillion U.S. dollar-pegged stablecoins circulating worldwide. Revised Payment Services Act, the law regulating stablecoins, is scheduled to be enforced in Japan by June this year, ahead of the U.S. and the EU, and since stable coins can be issued not only in Japanese yen but also in other currencies around the world, this is considered to be a great business opportunity for Japanese financial institutions, including the possibility that Japan will be responsible for global settlements. 

G.U.Technologies Inc. is developing the stablecoin system that can be easily introduced by financial institutions and fund transfer operators, with placing importance on practicalities such as legal compliance and payment processing speed, hopefully supporting the world where various financial institutions issue their own stablecoin.

■ ”Japan Open Chain”, a public blockchain fully compatible with Ethereum and compliant with Japanese law


There are several blockchain networks in the world. The actual operating body, however, is unclear and there are many legal and technical problems that make it difficult to promote web3 business on such blockchains.
While various problems such as fraud occur, there is a need for blockchains that complies with the laws of each country and allows businesses to operate with peace of mind.

Therefore, Japan Open Chain was established to promote web3 business for people around the world by providing the necessary decentralization, high security performance and stability, and by ensuring that reliable Japanese companies operate in compliance with Japanese law.

Currently, it is jointly operated by six companies within the Sony group: Corgear Corporation, Dentsu Inc., G.U.Technologies Inc., Minna-no Bank, Inc., Pixiv Inc. and Kyoto University of Art and Design, and will eventually grow to 21 companies.
