Reviewed assessment
Identity and current state
This summary reports reviewed facts and uncertainty. It is not a rating or recommendation.Ethereum ERC-20 token targeting 1 JPY per JPYR. Current JPYR first-party materials make conflicting backing descriptions: the project site says JPYR is 100% backed by reserves, while the whitepaper describes issuance matched to Ethereum deposited in DeFi. No independently reviewed reserve series or direct holder redemption right is established. Market access materially tightened in September 2026 when BTSE delisted JPYR and IZAKA-YA announced a Japan-facing service exit; these restrictions do not by themselves establish a depeg, reserve impairment, or global token shutdown.

- Classification notes
- JPY-referenced ERC-20 stablecoin classification. Public backing descriptions remain materially inconsistent, direct issuer redemption is unresolved, and no independent reserve-assurance series is established. Lifecycle is restricted because BTSE delisted JPYR and disabled deposits/trading on 2026-09-15 and the IZAKA-YA ecosystem announced a Japan-facing service exit on 2026-09-17; this does not imply depeg, reserve failure, or global termination.
Reserve and redemption
Reserve and redemption
Recorded components, disclosures, reports, and redemption conditions remain explicit.Reserve components
- Backing composition unresolved: current first-party project sources conflict between generic reserve backing and Ethereum-in-DeFi collateral, and no independently assured token-specific reserve composition is establishedUnknown after review · This explicit unknown component preserves the unresolved reserve boundary. The homepage reserve claim and whitepaper Ethereum/DeFi collateral claim are both first-party statements and are not reconciled by inference. SOG does not invent cash, bank deposits, crypto allocation, custody, reserve shares or assurance facts.

| Backing types | Unknown after review |
| Summary | Current JPYR first-party sources do not establish a single consistent backing model. The project homepage says JPYR is 100% backed by reserves, while the project whitepaper says issuance is managed to match Ethereum deposited in DeFi. No independently assured token-specific reserve series, liability matching, custodian statement or audit opinion is established in the reviewed record. |

- Notes
- Ethereum contract identity is published by an IZAKA-YA-affiliated MetaMask guide and corroborated by Etherscan. Affiliated material states that mint, burn and transfer-stop functionality exists and also states that no formal third-party audit had been completed as of June 2026. Current role-holder addresses, upgradeability, pause/freeze state, mint policy, burn policy and first on-chain issuance date remain unresolved.

Missing or disputed facts remain visible instead of being converted into certainty.| Topic | What remains unclear | Value state | Priority | Last checked |
|---|---|---|---|---|
| Legal Issuer and Redemption Obligor | Affiliated public material names a JPYR Organization, but reviewed sources do not establish the exact incorporated legal issuer, jurisdiction, holder legal claim, direct redemption obligor, or bankruptcy priority. | Unknown after review | High | 2026-09-20 |
| Backing Model and Independent Reserve Assurance | Current JPYR first-party sources materially conflict: the project homepage says JPYR is 100% backed by reserves, while the project whitepaper says issuance is managed to match Ethereum deposited in DeFi. No complete independently reviewable reserve series, liabilities matching, custodian statement or assurance opinion was identified. | Unknown after review | High | 2026-09-20 |
| Direct Redemption Right and Terms | Reviewed public material still does not establish who can redeem JPYR directly with the issuer, whether par redemption is a contractual holder right, minimums, fees, settlement timing, eligible jurisdictions or the settlement counterparty. BTSE's withdrawal window after delisting is an exchange custody exit path, not direct issuer redemption. | Unknown after review | High | 2026-09-20 |

| Regulatory Status and Market Liquidity | JPYR-affiliated material previously stated that JPYR was not registered with Japan's FSA and described liquidity as limited. By 2026-09-15 BTSE had delisted JPYR and disabled deposits/trading; on 2026-09-17 IZAKA-YA announced a Japan-facing service exit.
