Summary
Mitsui & Co. Digital Commodities (MDC), a subsidiary of Japan's Mitsui & Co., has launched Zipangcoin (ZPG) onto Optimism's OP Mainnet, executing a strategic migration of its tokenized precious metals asset from a proprietary private blockchain to public infrastructure. Since its 2022 inception, ZPG—backed by physical gold, silver, and platinum reserves—operated exclusively on Miyabi, a private blockchain developed by crypto exchange bitFlyer. The April 17, 2026 deployment marks the first time the asset will be issued in a public blockchain ecosystem, significantly expanding distribution channels and global accessibility.
The timing positions ZPG for immediate institutional adoption: Japanese exchange GMO Coin will list the token on April 20, 2026, enabling regulated trading within Japan's established cryptocurrency framework. MDC's leadership emphasized the asset's compliance pedigree, with Representative Director & Sho Miichi stating that "Zipangcoin's strength lies in the safety and transparency we have built since 2022 under Japan's rigorous regulatory framework." Kyle Jenke, Chief Business Officer at OP Labs, characterized Japan's regulatory environment as "one of the most compelling markets for on-chain finance," signaling institutional confidence in the jurisdiction's approach to digital assets.
The selection of Optimism reflects deliberate infrastructure evaluation. MDC highlighted that OP Stack chains processed over 6 billion transactions in 2025—representing 29x growth over two years. The network currently supports $1.1 billion in bridged TVL, a $538 million stablecoin market cap, and $165 million in weekly DEX volume, demonstrating sufficient liquidity and ecosystem maturity for regulated commodity issuance. This deployment aligns with broader institutional momentum: on-chain tokenized real-world assets (RWAs) tripled to approximately $18.6 billion during 2025, with industry analysts projecting the market could reach $2 trillion by 2030.
Mitsui & Co.'s involvement elevates the deployment's institutional credibility. As a Fortune Global 500 trading conglomerate with a $94 billion market cap and Berkshire Hathaway as its largest shareholder, the parent company provides significant capital and operational backing. The move reflects accelerating convergence between commodity trading, financial infrastructure, and blockchain settlement systems, positioning tokenized metals as an emerging asset class for diversified institutional portfolios seeking regulated, physically-backed digital exposure to precious metals.
