The dollar/yen pair has been hovering around 159.42, flirting with the psychologically loaded 160 level that has historically triggered market interventions from Japanese authorities.
The core issue is deceptively simple. A stablecoin pegged to the US dollar is only “stable” relative to the dollar. If you’re a Japanese business settling invoices in a USD-pegged token while the yen gyrates by several percent in a week, the word “stable” starts doing a lot of heavy lifting.
Yen stablecoins enter the picture
Japan has been building its answer to this problem. JPYC, the country’s first FSA-compliant stablecoin, launched in October 2025 with full backing from yen reserves and Japanese Government Bonds. It operates under Japan’s amended Payment Services Act, which provides a regulatory framework for licensed issuance of yen-pegged tokens.
The token has already attracted institutional interest. AZ-COM Maruwa Holdings poured a ¥1 billion investment into JPYC’s enterprise use case in July 2026.
