Practical guide to obtaining
and redeeming JPYC

This guide is built primarily on official public information from jpyc.co.jp↗, ex.jpyc.co.jp↗, the JPYC official FAQ, and public materials from the Financial Services Agency↗ and the National Tax Agency↗. As supplements, we used Japanese-language articles from major domestic crypto exchanges and crypto media to fill in alternative routes and market-side practice.

For unspecified items, the assumptions are: the user is an individual resident in Japan; no specific exchange or wallet is preferred; the account is not corporate; and the user is not a US tax resident. Corporate use brings beneficial-owner and contact verification into the picture. US tax-resident users currently cannot open a JPYC EX account.

The official FAQ does carry articles on items such as "minimums and maximums for issuance and redemption" and "issuance / redemption / refund fees", but for some of those we were unable to fully retrieve the body text from the surveyed snapshot. Where we could not confirm a specific number from official body text, the section below marks it as unconfirmed.

Redemption requires more careful adherence to the rules than issuance does. The two most important points are: create the redemption reservation first, and send only from a registered wallet. The official FAQ instructs that you must complete a redemption reservation in advance whenever you want to redeem your JPYC into yen.

On the redemption reservation screen, you enter the JPYC amount you want to send. The snapshot shows that as you enter the amount, the equivalent yen amount is displayed automatically — redemption also runs on the 1 JPYC = ¥1 basis. You then send the JPYC from a registered wallet under the conditions shown.

The operational risk here is significant. The official FAQ states that transfers from a wallet address that has not been registered will not be processed, and that transfers from any address other than the designated wallet may not be identifiable as the redemption transfer — and may therefore not be eligible for compensation or return. In practice, this means: if you send JPYC you received via DEX or P2P from a wallet you have not yet registered with JPYC EX, you can get stuck.

Once the on-chain transfer is confirmed, JPYC EX initiates a yen bank transfer to the registered bank account. The official top page explains that after the transaction confirmation completes, the funds are wired to the registered bank account. Here too, banking, network conditions, and AML/CFT monitoring can introduce delay.

Note that the current JPYC and the older JPYC Prepaid are different tokens. The issuer's public material states that they are different and that the issuer does not accept exchange between them. Before any redemption, verify whether what you hold is current JPYC or the legacy JPYC Prepaid.

The frame to keep in mind: obtaining JPYC on the market and having the issuer redeem it 1:1 are different things. Current official JPYC is issued on Ethereum, Polygon, and Avalanche; the older JPYC Prepaid lives on a wider set of chains (Ethereum, Polygon, Gnosis, Shiden, Avalanche, Astar, etc.). The two are different tokens, and the issuer does not accept exchange between them. Confuse the two and you can end up on the right chain with the wrong token, unable to redeem.

Centralized exchanges (CEX)

In practical terms, centralized exchanges aren't currently the place to buy JPYC itself — they're the place to buy gas and bridging assets that get you to JPYC. Coincheck↗, for example, has explicitly stated that it does not support JPYC. The typical flow is: buy ETH / AVAX / POL on a Japanese CEX → withdraw to a self-custodial wallet → swap into JPYC on a same-chain DEX. Going back to yen is the reverse: JPYC → DEX swap into a major crypto-asset → deposit to the Japanese CEX → sell and withdraw. Convenient, but the price isn't 1:1 — spread, liquidity, gas, and additional taxable events all enter.

DEX / in-wallet swap

DEX or in-wallet swaps are a fairly realistic way to obtain JPYC. As the educational material from Japanese exchanges notes, DEX trades are crypto-to-crypto, generally don't require KYC, but cannot bridge directly to fiat and don't come with support. So you can't go straight from yen to JPYC inside a DEX — you need a CEX or already-held crypto upstream.

On the wallet-integrated path, Japanese reporting describes HashPort Wallet↗ integrating 1inch↗'s Swap API and using Kana Labs↗ to enable cross-chain direct swaps including JPYC. If that performs as described, the experience of "bring an asset from another chain and turn it into JPYC" is meaningfully better — but it remains a market trade, not official redemption.

P2P

P2P is the simplest technically: someone who already holds JPYC sends it directly to your wallet. The catch is that you have to verify what you actually received — is it really current JPYC, is it a counterfeit, is it on a supported chain, is it the official contract? The official FAQ explicitly warns about counterfeit tokens, which cannot be redeemed for yen. And if you intend to redeem later, that receiving wallet has to either be registered with your JPYC EX account, or the JPYC has to be moved to a registered wallet first.

OTC

OTC can be useful in size, but in this survey we could not confirm a publicly published OTC offering from the issuer for general counterparties. Under Japanese law, buying or selling, exchanging, and providing yen on-/off-ramps for electronic payment instruments as a business generally implicates the registration regime for electronic-payment-instrument-related business. So it's not "this is a large trade so we'll just do OTC" — it's "is the counterparty a registered, compliant operator? how is price set? is the final yen settlement official redemption or a market sale?" For corporates, the safer order is to default to the official route, or to a clearly compliant counterparty, before considering OTC.

Legally, JPYC is not itself a crypto-asset — it is treated as an electronic payment instrument under the Japanese Payment Services Act. The Financial Services Agency↗ support-desk Q&A explains that to issue an electronic payment instrument domestically, you generally need fund-transfer service registration, or a trust-based legal structure. Buying, selling, and exchanging electronic payment instruments as a business — including operating yen on- and off-ramps — falls under registration as an electronic-payment-instrument-related business. JPYC, Inc. appears on the public list of registered fund-transfer operators and is referred to as such in FSA communications.

On AML/KYC, JPYC EX is on the strict end of the spectrum. Per the official FAQ, individual eKYC requires a My Number Card and a dedicated app. Account opening collects declarations of US tax residency, foreign-PEP status, nationality, and country of residence. US tax residents currently cannot open an account. The FSA also formally recognizes online identity-verification methods using public personal authentication and IC-chip data.

Tax treatment differs for corporations and individuals. For corporations, the National Tax Agency↗ FAQ is relatively clear: electronic payment instruments are treated as something close to a monetary claim similar to a demand deposit. Acquisition is recorded at face value, gain or loss is recognized against book value when transferred to a third party, and no period-end mark-to-market is required. If a corporation uses JPYC for everyday settlement and remittance, that treatment is meaningful.

For individuals, within the official material we surveyed there is no concise individual-income-tax FAQ written specifically with JPYC in mind. Separately, the NTA notes that crypto-assets generate taxable events on sale, exchange, and use for settlement. Practically, that means: if you cycle JPYC purely through 1:1 official issuance and redemption, price gaps are minimal; but routes that involve selling or swapping ETH or AVAX to obtain JPYC, or unwinding JPYC through a crypto-asset back to yen, can trigger taxable disposals on the crypto side. This is not about JPYC's price — it's about the disposal of the crypto-asset used along the way. The transfer of an electronic payment instrument is consumption-tax-exempt.

A handful of operational rules can also stop a redemption cold, and they should be internalized before the fee schedule. First, an inbound transfer without a reservation will not produce JPYC. Second, the katakana sender name must exactly match the registered account name. Third, redemption transfers must come from a registered wallet — non-registered or wrong-source addresses risk failed settlement. Fourth, counterfeit tokens cannot be redeemed. Fifth, legacy JPYC Prepaid is a different token from current JPYC. Treat these as the stuck-points before you worry about fees.
