Stablecoins are a category of crypto assets designed to maintain a stable value by being backed with fiat currency, real-world assets (RWA), or cryptocurrencies. Their main purpose is to avoid the high volatility of the crypto market while keeping a one-to-one value peg with fiat currencies. The primary types include fiat-backed, crypto-backed, algorithmic, and commodity-backed stablecoins.
In recent years, Japan has moved forward with stablecoin regulations. The enforcement of the revised Payment Services Act has heightened interest in stablecoins. USDC, a dollar-backed stablecoin, is expected to become available through partnerships with SBI and Coincheck. If stablecoins see widespread adoption, they could streamline corporate settlements—worth up to ¥1,000 trillion annually—and boost transparency in areas like tax auditing.
Fiat-backed stablecoins are issued against collateral in fiat currencies, such as the US dollar or euro. These coins aim to maintain parity with their underlying currency—e.g., 1 coin = $1.
This type is highly trusted and carries low price volatility, making it a popular and stable choice in the crypto market. USDT and USDC are prime examples, available across many exchanges. Fiat-backed models are supported by real currency reserves, offering the highest level of stability.
Crypto-backed stablecoins are issued using cryptocurrencies—such as Bitcoin or Ethereum—as collateral. To address price volatility, issuers typically hold more collateral than the value of stablecoins in circulation.
For example, DAI is managed by smart contracts and is widely used in the DeFi market. Because these coins operate without centralized oversight, they play a central role in decentralized finance (DeFi) ecosystems.
Algorithmic stablecoins do not use fiat or cryptocurrencies as collateral. Instead, they stabilize value by dynamically adjusting supply through algorithms. These systems automatically manage supply and demand to keep prices near $1, but full stability remains a challenge.
While theoretically efficient, this model is vulnerable to extreme market swings. There have been instances where algorithmic stablecoins lost their peg, so users should proceed with caution.
Commodity-backed stablecoins are issued against RWAs such as gold or oil. Some offer price stability by linking directly to RWAs. These coins especially appeal to users seeking long-term value preservation or inflation hedging through investment in physical assets.
Gold-backed stablecoins, which track the price of gold, are attractive to investors seeking to avoid fiat currency risk.
Hybrid stablecoins combine multiple assets—fiat, cryptocurrencies, or commodities—as collateral to diversify risk and enhance price stability. By mixing various asset types, they reduce exposure to a single market and are designed to adapt to diverse conditions.
This approach can deliver more resilient price stability than models that rely on a single collateral asset.
Security token-backed stablecoins use tokenized financial assets—such as stocks or real estate—as collateral. As digitization of financial products and real estate progresses, security tokens are expected to see increasing use as new collateral assets.
Blending traditional financial assets with blockchain technology is expected to bring greater transparency to asset management.
The following table compares the main features of leading stablecoins. Each uses different mechanisms and collateral strategies, so users can choose based on their preferences.

Stablecoins and Bitcoin are both crypto assets, but their use cases and characteristics are distinct. The following table highlights the main differences.
| Feature | Stablecoin | Bitcoin |
|---|---|---|
| Purpose | Means of payment and settlement with stable value | Decentralized digital currency and investment asset |
| Price Stability | Pegged to fiat currencies or assets; price is stable | Highly volatile, driven by market supply and demand |
| Collateral | Backed by US dollars, euros, gold, crypto, etc. | No collateral; supported by Proof of Work |
| Issuance | Centralized or decentralized protocols | Fully decentralized, capped at 21 million BTC |
| Use Case | Ideal for payments and settlements due to stability | Used for investment, store of value, and trading—but price is volatile |
Stablecoins are pegged to fiat currencies like the dollar or euro, making their prices stable and suitable for day-to-day payments and remittances. Bitcoin is highly sensitive to market trends, leading to large price swings—making it more suitable as an investment or store of value.
This difference means stablecoins are practical for payments, while Bitcoin serves a distinct role as an investment asset.
Stablecoins are issued by central entities or smart contracts and backed with fiat or other assets. Bitcoin is fully decentralized with a fixed supply cap.
This difference allows stablecoins to flexibly adjust supply, while Bitcoin’s scarcity remains preserved.
Stablecoins are ideal for remittances and business transactions. Bitcoin is often seen as "digital gold" and mainly used for investment and value preservation.
The two types complement each other, so users can select according to their needs.
Stablecoins offer a range of advantages, but also have some drawbacks. Here’s a closer look at their main pros and cons.
Stablecoins leverage blockchain technology to enable international transfers and payments in near real time. Compared to the traditional banking system, fees are lower and transactions are faster.
International remittances that once took days can now be completed in minutes or hours using stablecoins.
Many stablecoin issuers regularly disclose collateral details and holdings. USDC and TrueUSD, for example, undergo external audits to strengthen trust.
This transparency allows users to verify that stablecoins are properly backed and use them with confidence.
Stablecoins include options pegged to the dollar, euro, gold, and other cryptocurrencies, allowing users to select the best fit for their needs.
For example, those seeking to avoid dollar volatility may choose a gold-backed coin, while DeFi-focused users may prefer a crypto-backed stablecoin for use cases like DeFi.
In Japan, Progmat and JPYC are among the companies advancing stablecoin issuance. This is particularly appealing for domestic and international businesses seeking yen-denominated digital assets.
As yen-based stablecoins become more widespread, domestic payments and remittances will become more efficient and drive improvements in B2B transactions.
Japan is standardizing tax rules for stablecoin transactions, but processing can still be complicated.
In particular, exchanging between stablecoins or converting to fiat currency may be taxable, requiring careful record-keeping and reporting.
Using stablecoins demands a basic understanding of blockchain and crypto assets. For beginners, this can be a barrier, and users must understand how to use them safely and correctly.
Proper wallet management, private key storage, and transaction verification are all required, making education and outreach critical.
Stablecoin acceptance remains limited, and most retail businesses and services do not yet support them. While widely used in crypto markets, they are not common as a daily payment method—at least not yet.
However, more businesses and services are starting to accept stablecoins, and broader adoption is expected.
Stablecoins are pegged to fiat or assets, but market volatility or lack of issuer transparency can cause the peg to break. Algorithmic stablecoins are especially prone to price swings.
There have been cases of stablecoins losing their peg and causing major losses, so it’s important to check issuer credibility and collateral status before use.
Stablecoins come in various forms—fiat-backed, crypto-backed, algorithmic, and commodity-backed. Each type has its own risks and benefits, so users can choose according to their objectives.
Fiat-backed stablecoins like USDC and USDT offer strong price stability and are ideal for business payments and remittances. Crypto-backed models like DAI are popular among users seeking decentralized alternatives.
Stablecoins also provide a hedge against crypto market volatility, including Bitcoin. In Japan, yen-based stablecoins like Progmat and JPYC are set for launch, expanding use cases locally and abroad.
With more options, users can manage assets and transact efficiently while minimizing risk. Continued regulatory improvements and innovation are likely to make stablecoins even more important in the years ahead.
A stablecoin is a crypto asset tied to the value of a fiat currency like the US dollar. Regular crypto assets can experience large price swings, but stablecoins are designed for price stability, making them suitable for payments and remittances.
DAI, USDT, and USDC are recommended in Japan. DAI is a crypto-backed, dollar-pegged stablecoin with strong stability. USDT and USDC are fiat-backed, widely used globally, and offer ample liquidity. The right choice depends on your needs.
Stablecoins include fiat-backed, crypto-backed, algorithmic, and commodity-backed models. Fiat-backed coins use currencies like the dollar as collateral; crypto-backed coins use cryptocurrencies; algorithmic models have no collateral and rely on algorithms; commodity-backed coins are linked to physical assets such as gold.
A stablecoin’s safety depends on the issuer’s credibility. Key risks include lack of reserve transparency, regulatory uncertainty, liquidity issues, and the ability to maintain value during market volatility. Always choose reputable issuers.
Stablecoins are mainly used for fast, low-cost international remittances and payments, as base currencies in DeFi platforms, and as an on-ramp/off-ramp for crypto trading due to their stable value.
You can purchase stablecoins at major Japanese crypto exchanges. DAI and ZPG, for example, are available domestically and can be bought easily through each platform. Check exchange websites for the latest supported assets.
Overseas stablecoins (USDT, USDC) are dollar-pegged and aimed at international use. USDT is highly liquid and widely adopted but has transparency concerns. USDC is strong on regulatory compliance and transparency. Japanese stablecoins are yen-pegged, focused on domestic payments, and comply with Japanese regulations.
Stablecoin tax treatment depends on the type. Crypto-backed coins are taxed like other crypto assets, with gains taxed upon sale. Digital-money-type coins are treated more like cash, using fiat rates. Gains must be reported at the time of transaction.
Yes, stablecoins are designed for price stability and are suitable for long-term holding. However, verify issuer reliability, regulatory changes, and collateral transparency before holding.
In 2024, JPYC is a standout in Japan. It is yen-pegged, backed by assets like bank deposits and government bonds, and expected to play a major role in instant, low-cost international transfers and cross-border payments.
