Japan's Yen Stablecoin vs USDT: Which Should You Use?
Something historic happened in Japan's crypto market in October 2025. JPYC Inc. became the first company to launch a fully regulated yen-pegged stablecoin under the amended Payment Services Act. By December, SBI Holdings and Startale Group announced a second yen stablecoin (JPYSC) for Q2 2026, backed by SBI Shinsei Trust Bank. Japan's three megabanks (MUFG, SMBC, Mizuho) are piloting their own versions. For the first time, Japanese users have a choice: domestic yen stablecoins or global dollar stablecoins like USDT. The right answer depends entirely on what you are trying to do.
Japan's Stablecoin Landscape in 2026
Japan moved faster than most countries expected. The amended Payment Services Act (June 2023) created a legal framework requiring stablecoin issuers to be licensed banks, trust companies, or fund transfer service providers. Full fiat reserve backing and segregated custody are mandatory. This is the strictest stablecoin regulation in Asia.
By late 2025, the framework started producing real products. JPYC Inc., backed by investors including Circle (the company behind USDC), launched the first yen stablecoin on Ethereum. SBI Holdings and Startale Group signed an MoU for JPYSC, a yen stablecoin issued through SBI Shinsei Trust Bank and distributed by SBI VC Trade. In November, the FSA greenlit a pilot by three megabanks (MUFG, SMBC, Mizuho) using the Progmat platform.
As Kyle Ellicott of Stacks Asia Foundation told DL News: "The issuance of approved and licensed yen-denominated stablecoins will increase fivefold by the end of 2026." Japan's approach is regulation-first, innovation-second. Every yen stablecoin is supervised, institutionally backed, and closer to digital bank money than a crypto-native token like USDT.

When to Use Yen Stablecoins
Yen stablecoins make sense for domestic Japanese payments where regulatory compliance matters: business-to-business settlements, e-commerce within Japan, tourism-related transactions, and any use case where operating within the FSA framework is important. They are also potentially useful for yen-denominated cross-border settlements within Asia once liquidity grows.
The regulatory clarity is the key advantage. Companies dealing with Japanese banks and financial institutions will find yen stablecoins far easier to explain and justify than USDT.
When USDT Wins
For sending money to family in the Philippines. For receiving freelance payment from a client in the US. For moving funds to a P2P platform in Vietnam. For anything involving a destination outside Japan's regulated financial system, USDT on Tron remains the practical choice.
The reason is simple: liquidity. JPYC has a market cap in the tens of millions of dollars. USDT has $155 billion. When you need to convert stablecoins to local currency in Bangkok, Lagos, or Istanbul, there are hundreds of P2P traders offering USDT/local currency pairs. There are zero offering JPYC.
Japan's yen stablecoins will likely grow into significant domestic instruments. But USDT's network effect in international transfers is a decade ahead. For the foreseeable future, Japanese users who need to send value across borders will use both: yen stablecoins for domestic, USDT for international.
Cutting the USDT Transfer Fee
If you send USDT from a Japanese wallet (TronLink, Trust Wallet, or Bitbank withdrawal) via TRC-20, the standard network fee is 6.4 TRX. This applies whether you are sending to another Japanese user or to someone in Southeast Asia. With Energy delegation, the fee drops to 3-4 TRX.
