⛩️ Welcome to Matsuri Coin (MTC)
A bridge of 和 (wa — harmony): from competition to co-creation.
Whether you experience Japanese culture, deliver it, or protect it — every form of involvement becomes economic value that sustains culture's future. That is Matsuri Coin (MTC): a utility token on Solana, woven through a platform you can download and use today.
One platform, four surfaces, one token
The Matsuri ecosystem ships as three native iOS apps plus a full web platform, built by Jon & Coo Inc. (Japan) and stitched together by a single token.
Book tours, events, meetups, and classes; pay with cards, Solana, or MTC; mine MTC at sacred sites with 参拝マイニング (sanpai mining — worship mining); and carry an offline Disaster Lifeline in your pocket. Live at matsuri.group.
Articles, podcasts, and video about Japanese culture. Reading, listening, and watching pay MTC through media mining. Live at j-times.org.
The operations app for GCF (Global Community Friends): guide dashboards, member management, and revenue tracking for the people who deliver culture. Portal at gcf.works — see GCF Membership.
The full platform in any browser: experiences, restaurant booking, the Matsuri Shop, crowdfunding, and live streaming — in six content languages.
A utility token on the Solana blockchain. More than a means of payment, MTC connects the people who come to Japan with the culture worth protecting — a co-created cultural economy where experience and commerce circulate together. Every surface above earns it, spends it, or both.

Built on Solana. Finality in roughly 0.4 seconds and fees around $0.0003 (about ¥0.04) per transfer (Q1 2026) make micro-rewards — a shrine check-in, an article read, a ¥300 tip to a guide — economically sane. The full rationale is in Why Solana?, and the architecture rule that keeps users safe (apps never touch the chain directly — always app → backend → Solana) is in Product & Technology.
📲 Shipping, not promising
This whitepaper describes software that already exists. All three iOS apps are released and live on the App Store — bookings, payments, the in-app wallet, worship mining, and the disaster lifeline are shipping today.
