How to Buy Tether (USDT): A Beginner’s Guide to Purchasing and Network Management

Tether (USDT) is one of the most widely used stablecoins in the world, with a market capitalization exceeding $60 billion as of 2025. Backed 1:1 by U.S. dollars and issued by Tether Ltd., USDT offers price stability, making it a preferred choice for cryptocurrency trading, NFT purchases, and cross-border transactions.

However, many beginners face a common challenge: Tether is not available on Japanese domestic exchanges, meaning users must turn to overseas platforms to buy and manage USDT. This guide walks you through everything you need to know — from how to buy USDT on international exchanges like Binance and Bybit, to managing blockchain networks for NFT transactions, and key considerations before investing.

Whether you're new to crypto or expanding your digital asset toolkit, this step-by-step breakdown ensures clarity, safety, and efficiency.

Where Can You Buy Tether (USDT)?

Only Available on Overseas Exchanges

As of 2025, Tether (USDT) cannot be purchased directly on Japanese domestic exchanges such as CoinCheck or GMO Coin. Instead, it's primarily traded on major international platforms like Binance and Bybit, which support high-volume USDT trading pairs.

Among these, Binance stands out due to its massive liquidity, low fees, and user-friendly Japanese-language app — making it ideal for beginners.

Step-by-Step: How to Buy USDT from Japan

Since direct yen deposits aren’t supported on most overseas exchanges, you’ll need to transfer crypto from a domestic exchange first. Here’s the full process:

Step 1: Open an Account at a Japanese Exchange

Start by registering with a regulated Japanese exchange like Bitbank or SBI VC Trade. These platforms allow you to buy major cryptocurrencies using JPY.

• Account verification typically takes 1–3 business days.
• You’ll need identification documents (e.g., driver’s license or My Number card).
• Once verified, deposit JPY and purchase a transfer-friendly coin like XRP (Ripple) or ETH (Ethereum) — XRP is popular due to low network fees.

Step 2: Transfer Crypto to an Overseas Exchange

After purchasing crypto domestically, send it to your overseas exchange wallet:

1. Log into your overseas exchange (e.g., Binance or Bybit).
2. Copy your deposit address for the specific cryptocurrency (e.g., XRP).
3. On your domestic exchange, initiate a withdrawal and paste the address.
4. Confirm the transaction.

⚠️ Always double-check addresses. Sending funds to the wrong network can result in permanent loss.

How to Buy USDT on Binance

Once your crypto arrives at Binance, converting it to USDT is simple.

Option 1: Convert Crypto to USDT (Recommended for Beginners)

This method uses Binance’s built-in “Convert” feature — fast, easy, and doesn’t require using the trading interface.

Steps:

1. Go to Wallet > Overview.
2. Click Convert.
3. Select the cryptocurrency you sent (e.g., XRP).
4. Choose USDT as the target.
5. Enter the amount and confirm.

The conversion completes instantly at market rate, with minimal slippage.

Option 2: Buy USDT with Credit Card

You can also buy USDT directly using a VISA or Mastercard:

1. Navigate to Buy Crypto > Credit/Debit Card.
2. Select USDT and enter the JPY or USD amount.
3. Complete KYC if prompted.
4. Register your card and confirm payment.

💳 Note: Credit card purchases carry a ~2% fee, higher than crypto conversion, but eliminate the need for domestic transfers.

👉 Skip intermediate steps and buy USDT directly with flexible payment options.

How to Buy USDT on Bybit

Bybit offers a similar workflow with slight interface differences.

Option 1: Convert Crypto via Derivatives Wallet

Due to platform structure, you may need to move assets before conversion:

Steps:

1. Transfer crypto from your domestic exchange to Bybit.
2. Tap Assets > Spot.
3. Click Transfer → Move funds to Derivatives Wallet.
4. Go to Derivatives > Exchange.
5. Select your crypto and swap it for USDT.

Option 2: One-Click Purchase with Credit Card

1. Go to Buy Crypto > One-Click Buy.
2. Choose USDT, input amount.
3. Select Credit Card as payment method.
4. Add card details and complete purchase.

Same as Binance, expect fees around 2–3%.

Understanding USDT Blockchain Networks (Chains)

One critical aspect often overlooked: USDT exists across multiple blockchains, such as Ethereum (ERC-20), TRON (TRC-20), and Polygon.

🔗 Example:

• USDT on Ethereum → Higher fees (~$5–$50)
• USDT on TRON → Low fees (~$1)
• USDT on Polygon → Ideal for NFTs and DeFi apps

If you're using USDT for NFT purchases, ensure it's on a chain compatible with the marketplace (e.g., OpenSea supports Polygon).

How to Change USDT Chain Using Polygon Bridge

To switch networks, use a bridge tool like Polygon Web Wallet:

Step-by-Step Guide:

1. Install MetaMask (browser extension or mobile app).
2. Securely back up your recovery phrase — never share it online.

3. Add Polygon Network to MetaMask:

   • RPC URL: https://polygon-rpc.com
   • Chain ID: 137
4. Add your MetaMask address as a withdrawal destination on Bybit or Binance.
5. Send USDT from exchange to MetaMask (ensure correct network!).
6. Visit Polygon Bridge and transfer USDT from Ethereum to Polygon.

This process enables low-cost NFT transactions and access to decentralized apps.

How Much Does 1 USDT Cost in JPY?

As of 2025, 1 USDT trades around ¥158–¥162, closely pegged to the U.S. dollar. Minor fluctuations occur due to supply/demand but rarely exceed ±1%.

You can buy fractional amounts — even $1 worth of USDT — on both Binance and Bybit, making it accessible for all budget levels.

Key Tips & Risks When Buying USDT

Before diving in, consider these essential points:

1. Use Only Surplus Funds

While USDT is stable, it’s not risk-free. Regulatory changes or issuer issues could impact its peg. Only invest money you can afford to lose or lock up temporarily.

2. No Domestic Regulation in Japan

Japanese financial authorities do not regulate Tether or overseas exchanges. While convenient, this means less consumer protection compared to domestic platforms.

3. Keep a Domestic Exchange Account Ready

Overseas platforms don’t support JPY withdrawals. To cash out:

• Convert USDT → XRP/ETH/BTC on Binance/Bybit.
• Withdraw crypto to Bitbank or SBI VC Trade.
• Sell for JPY and transfer to your bank.

Choose exchanges with low or zero deposit fees for smoother exits.

What Is Tether (USDT)?

A Dollar-Backed Stablecoin

Tether (USDT) is a stablecoin pegged 1:1 to the U.S. dollar, issued by Tether Limited. Each USDT token is theoretically backed by equivalent reserves in cash or cash-like assets.

Unlike Bitcoin or Ethereum, USDT has no fixed supply cap — new tokens are minted as demand increases.

It serves two primary purposes:

• A stable store of value during market volatility.
• The base trading pair on most international crypto exchanges.

Future Outlook for Tether (USDT)

Continued Dominance in Crypto Markets

Despite competition from other stablecoins like USDC and DAI, Tether maintains the largest market share due to its early adoption, wide availability, and deep liquidity.

As global crypto trading volume grows — especially in Asia and emerging markets — demand for USDT is expected to remain strong.

Risks Depend on Tether’s Transparency

The biggest threat? Loss of trust in Tether Ltd.'s reserves. In 2019, concerns arose over whether Tether held full backing. While audits and settlements since then have reassured markets, ongoing scrutiny remains.

Always monitor official announcements from Tether for any changes in reserve composition or regulatory status.

Frequently Asked Questions (FAQ)

Can I buy USDT on Japanese exchanges?

No. As of 2025, no regulated Japanese exchange offers direct USDT trading pairs. You must use overseas platforms like Binance or Bybit.

What’s the best wallet for storing USDT?

MetaMask is highly recommended — especially if you plan to use USDT for NFTs or DeFi applications. It supports multiple chains including Ethereum, Polygon, and BSC.

Can I earn interest on USDT?

Yes. Platforms like Binance and Bybit offer flexible staking or savings programs where you can earn yield on idle USDT — typically between 3%–8% APY depending on market conditions.

Is USDT safe?

USDT is generally safe for short-term use and trading due to its stability and widespread acceptance. However, long-term holding carries counterparty risk tied to Tether Ltd.’s financial health.

Why does my NFT marketplace reject my USDT?

Most likely because the blockchain network doesn't match. For example, if your USDT is on Ethereum but the NFT platform uses Polygon, you’ll need to bridge it first.

Are there cheaper alternatives to Binance/Bybit?

MEXC and KuCoin also offer competitive rates and lower withdrawal fees (e.g., TRC-20 USDT at ~$1). However, they may have less robust security or limited Japanese support.

Final Thoughts: Getting Started with USDT

Buying Tether (USDT) from Japan requires using overseas exchanges like Binance or Bybit, transferring crypto from domestic platforms such as Bitbank, and understanding blockchain networks when using USDT for NFTs or DeFi.

With careful planning and awareness of risks, USDT becomes a powerful tool for participating in global crypto markets — offering stability, speed, and broad utility.

Whether you're trading altcoins, collecting digital art, or exploring Web3 opportunities, mastering USDT opens doors across the decentralized ecosystem.
