Demonstration Experiment of Corporate Settlement withthe Digital Currency DCJPY (tentative name)- Smart contracts linked to DCJPY aiming to improve the efficiency of corporate settlementrelated operations and to digitally integrate transactions and settlements. DeCurret DCP Inc. (HQ: Chiyoda-ward, Tokyo Japan, President: Satoshi Murabayashi, hereinafter"DeCurret DCP") is pleased to announce that Mitsubishi Corporation ("MC") and Nippon Telegraphand Telephone Corporation ("NTT") have conducted a demonstration experiment using the digitalcurrency DCJPY for the settlement of overdue shipping fees and other charges incurred in marinetransportation at the Digital Currency Forum, for which DeCurret DCP serves as the secretariat.
The Digital Currency Forum is an initiative to study the practicality of digital currency in Japan,
with the participation of over 80 companies, banks, local governments, organizations, experts, andrelevant ministries and central banks as observers from a wide range of fields including leading
Japanese banks, retail, transportation, information and communications.

Background
The Settlement in Industrial Distribution Subcommittee is working as a member of the Digital
Currency Forum to plan and promote demonstration experiments to gain a wide range ofknowledge on digital currency and smart contracts employing blockchain. In the settlement ofvarious fees in trade transactions, there are various issues such as duplication of work between
contracting parties, complicated operations from billing to settlement, and long time lags until
funds are made available. In this initiative, MC conducted a demonstration test of automatedcontract execution using digital currency for the settlement of overdue shipping charges andother charges related to trade transactions. The company conducted technological verificationand confirmed the effectiveness of the introduction of the technology. The implementation wascarried out in cooperation with Industry One, Inc. (Industry One), a joint venture established by
MC and NTT for the purpose of promoting industrial DX.

About the Digital Currency DCJPYThe Digital Currency DCJPY is designed as a "yen-denominated" digital currency that is fully
linked to the yen, and it is assumed for the time being that it will be issued as debt bycommercial banks. We are also considering the assumption that such obligations will bepositioned as "deposits".
The "Two-tier Digital Currency Platform" is a mechanism that links two areas, called the"Common Area" and the " Business Process Area," for issuing, remitting, and redeeming theDigital Currency DCJPY. The additional area can be programmed to meet various needs,
enabling the Digital Currency DCJPY to be used for settlement in a form linked to the flow ofgoods, for example.

Industry One: Overall planning, establishment of smart contract infrastructure, promotion andevaluation of verification experiments
DeCurret DCP: Provision of system for Two-tier Digital Currency issuance4.

Results of the demonstration experiment and future plans
This verification experiment proved that a mechanism for executing payments in the Digital
Currency DCJPY using smart contracts is effective in MC's trade transactions. It was also
confirmed that the Two-tiered Platform can be used in cooperation with businesses that wish toprogram and utilize the system in additional areas. The results showed that the automatic
execution of trade contracts using smart contracts enables consistent execution from deal
registration to settlement in a single system, and that it is expected to reduce the workload
related to business-to-business settlements by up to 80%.
We believe that a system like this one, which uses smart contracts to make payments in theDigital Currency DCJPY, will be effective for business-to-business settlement operations
common to small, medium, and large companies in Japan, and will be particularly effective forcompanies with a large number of settlements and highly complex operations.
In addition, digital payments using existing electronic money, etc., have often been limited ininteroperability because they aim to expand their own economic sphere and increase customer
loyalty within that sphere. In contrast, DCJPY, a Digital Currency, ensures interoperability
through a common domain, thus increasing convenience for customers and functioning as an
infrastructure for companies to build new services offered across economic zones.
Furthermore, by incorporating Digital Currency DCJPY functions into some of theapplications developed by the company and linking them to the common domain in a form thatcan be called "Digital Payment as a Service," digital currency payment services can beprovided as if they were part of the company's own broad range of services. The Digital
Currency DCJPY can be linked with companies in various ways.
The Digital Currency Forum will actively engage in discussions and initiatives from various
perspectives toward the realization of the private-sector-issued Digital Currency DCJPY.
