Points & rewards glossary: key Japanese terms
Plain-language definitions of the terms you meet across Japanese points programs — from limited-time points to SPU, tsumitate and touch payment.
This glossary defines the recurring terms in Japanese rewards — ordinary vs limited-time points, base vs effective rate, ecosystem, stacking, tsumitate and mileage transfer — so the rest of the hub reads clearly.
Key points
- Ordinary points last longer; limited-time points expire fast — spend them first.
- Base rate is advertised; effective rate is what you keep after caps and fees.
- “Ecosystem” ties a bank, card, wallet and phone plan into one point currency.
- Stacking layers card, code-payment and store points on one purchase, legitimately.
- Tsumitate is card-funded monthly investing that can also earn points.
Point types and value
Ordinary points (通常ポイント) are the standard balance, usually valid one to two years and redeemable across an ecosystem at roughly ¥1 each. Limited-time points (期間限定ポイント) are campaign points that expire within weeks to months and sometimes redeem only in narrow services — always spend these first. Base rate is the advertised earn (often 1% on cards), while effective rate is what you actually keep after caps, rounding, exclusions, fees and realistic redemption. Devaluation is when a program quietly lowers the value or raises the price of a redemption over time, which is why hoarding points is risky.
Ecosystems, stacking and payments
An ecosystem (経済圏) is a linked group of a bank, card, wallet, shopping site and phone plan that share one point currency — Rakuten, PayPay, d POINT and V Point are the big four. Stacking (二重取り・三重取り) means legitimately earning two or three rewards on one purchase by paying with a rewarding card, through a code-payment app, while presenting a store point. SPU (Super Point Up) is Rakuten’s tiered program that raises your rate as you use more services; PayPay Step is the equivalent for PayPay. Touch payment (タッチ決済) is contactless card or smartphone payment, and eligibility rules often distinguish smartphone contactless from physical-card touch and from iD/QUICPay.
Travel and investment terms
Miles (マイル) are airline loyalty currency in ANA Mileage Club or JAL Mileage Bank; a mile transfer converts ecosystem points into miles at a set ratio, and value per mile varies widely by redemption. An award flight (特典航空券) is a seat booked with miles rather than cash. Tsumitate (積立) is monthly accumulation investing; card-funded tsumitate lets a credit card pay for monthly fund purchases and earn points on that spend. Furusato nozei (ふるさと納税) is the hometown-tax donation scheme that returns goods and, on ecosystem platforms, points, while offsetting resident and income tax.

Frequently asked questions
What are limited-time points?
Limited-time points have a fixed, often short deadline and sometimes narrower redemption options than ordinary points. Rakuten, d POINT, and PayPay all distinguish some form of ordinary and limited-use rewards. Always check whether a headline bonus is ordinary or limited, spend limited-time points first, and set a reminder before they expire.
Can I stack store points and card points?
Frequently yes, when membership presentation and payment rewards are independently eligible. Scan the store loyalty card or app, then pay with a rewarding card or QR wallet. The key is that each layer must be eligible for the exact payment source — a wallet accepting a card as funding does not prove the charge earns points, and you must not add two rates that both include the same base.
How much is a point actually worth in Japan?
Most major points (Rakuten, PayPay, d, V) are worth about ¥1 each when spent on everyday purchases, which makes them easy to value. Some points are worth more when converted to airline miles under the right redemption, and less when locked to a single store or close to expiry. As a rule, treat ¥1 as the baseline and be skeptical of “inflated” valuations that assume perfect redemption.
