SUSHI TOP MARKETING INC. (Head Office: Chiyoda-ku, Tokyo; CEO: Daisuke Tokunaga; hereinafter “SUSHI TOP MARKETING”) has raised 100 million yen in its Series A 3rd round of funding, with Japan Post Capital Co., Ltd. (Head Office: Chiyoda-ku, Tokyo; President: Takaaki Adachi) as the investor.

　With this funding, SUSHI TOP MARKETING will further expand its initiatives in regional revitalization in collaboration with the Japan Post Group, connecting local cultures to the future through digital technology, and promoting regional economic support through blockchain across Japan.

A new way of engaging with local communities through blockchain.

We utilizes blockchain technology to digitally record and visualize local experiences, cultures, and economic activities, supporting a new model of regional revitalization.

In Ōda City, Shimane Prefecture — home to the World Heritage Site Iwami Ginzan — SUSHI TOP MARKETING has implemented a community co-creation digital stamp rally starting from local post offices.* By recording visitors’ activities as NFTs, the initiative contributes to revitalizing the regional economy through increased local circulation and helps preserve cultural assets. It has also led to higher foot traffic and retail performance at post offices, creating multifaceted synergies such as regional promotion in Tokyo utilizing the post office network.

In addition, SUSHI TOP MARKETING’s blockchain-based initiatives in the region have been selected for the Ministry of Land, Infrastructure, Transport and Tourism’s “Leading Project for Dual-Location Living Implementation Program” and the Ministry of Internal Affairs and Communications’ “Post Office Utilization Project.”

In Higashimatsushima City, Miyagi Prefecture, SUSHI TOP MARKETING is implementing a community co-creation NFT initiative utilizing the post office network. Serving as a regional digital infrastructure that connects tourism and local events, the project helps stimulate and revitalize the local economy.

*Following the positive reception of the Iwami Ginzan initiative, the third edition of the digital stamp rally is currently underway (Implementation period: October 15, 2025 – February 13, 2026).

These initiatives are attracting attention as a new model that visualizes the scale and depth of community engagement — previously difficult to measure — by recording regional activities on the blockchain through NFTs.

We are very pleased to have the opportunity to invest in such an outstanding company. SUSHI TOP MARKETING possesses innovative technology that allows anyone to naturally receive NFTs through an excellent user experience that doesn’t make users conscious of web3. This greatly enhances the value of our real-world customer touchpoints — the nationwide network of post offices. Going forward, we aim to further deepen our regional co-creation initiatives and expand this partnership across the entire Japan Post Group. Please look forward to the creation of a new customer experience that only our two companies — standing at the intersection of offline and online — can deliver.

We see this investment from Japan Post Capital as a ticket to the future we envision — a future where blockchain evolves from an advanced technology used by a few into a social infrastructure that anyone living in this country can use naturally. Through our collaborative projects centered around post offices in regions such as Iwami Ginzan and Higashimatsushima, we have become convinced of the immense potential when our technology connects with Japan’s extensive physical network. With this investment as a driving force, we will continue to create many real-world examples of how blockchain can enrich people’s daily lives. Please look forward to the quiet yet significant social transformation that SUSHI TOP MARKETING and the Japan Post Group will bring together.
