American Express Japan’s point program: how transfer partners rather than gift cards set the real value, and how expiry depends on enrolment.
Membership Rewards points are earned on American Express Japan cards; their value depends almost entirely on which transfer partner you use, and the expiry treatment depends on programme enrolment and activity.
Membership Rewards is the point program behind American Express Japan cards, from the Green Card through Gold Preferred and Platinum to the ANA co-brand products. Unlike a ¥1-per-point program, the earn rate tells you very little on its own: the same balance can be worth a modest amount as a statement credit and considerably more transferred to an airline partner and redeemed for a seat you would otherwise have paid cash for. That makes “which partner, at what rate, for which flight” the question that decides the program’s value, and it is why a Membership Rewards balance should be valued against a fare you would actually buy, minus award taxes and surcharges, rather than a fixed yen figure. Merchant-specific rates, bonus programmes and acquisition campaigns each carry separate conditions and should not be folded into the base rate.
Point-expiry treatment under Membership Rewards is not a single fixed rule: it depends on the programme options you are enrolled in and on account activity, and the terms have been revised over time, so the current member terms are the only safe reference. The same applies to transfers. Moving points to ANA miles at the favourable rate has historically depended on a paid enrolment, and annual transfer caps have applied — conditions that materially change how much of a large balance you can actually use in a year. The ANA co-brand Amex cards approach this differently by folding mile transfer into the product itself, with the gold tier including it rather than charging for it as an add-on, and the Diners-issued ANA card sits in a similar premium space with its own point rules. Before choosing a card on the strength of a transfer ratio, confirm the current enrolment requirement, rate and cap in the issuer’s own terms.

No. Most major points redeem near ¥1 when spent in-store or on the operator’s marketplace, but transferring to airline miles, merchandise, or another currency can yield well under ¥1. A store-locked balance like nanaco is less flexible even at the same nominal rate. Value each point at the redemption you will actually use.
