Costco Japan: Can You Use Your Membership From Home? Cards, Warehouses and Access (2026)

Japan · shopping · what works from home

By Nobu · membership terms, payment rules and warehouse data checked on Costco’s own sites on 19 October 2026 · Sources at the end

A Costco membership from the United States, Canada, the UK or Australia gets you into Costco in Japan: each of those countries’ membership terms says the card is valid at any Costco warehouse worldwide. Paying is different: Costco Japan lists cash, Mastercard credit cards, its own Shop Card and its co-branded card. Visa and American Express are not on that list. Its warehouse finder listed 37 warehouses on 19 October 2026, and only one has a Tokyo address.

The short answers

Your membership from home

The Costco US member conditions (updated 30 March 2026) say: “Your membership card is valid at any Costco warehouse worldwide and is not transferable.” Costco Canada and Costco UK use the same sentence; Costco Australia says the card “can be used at any Costco Warehouse worldwide”.

Costco Japan’s membership terms, last updated on 8 September 2025, describe its own cards: they are valid at any Costco warehouse worldwide, must carry a membership number and a full-face photo, and must be shown when you enter and when you pay. Copies are not accepted. They do not address cards issued abroad; your own country’s terms are the basis for using yours here.

If you have no membership, Costco Japan’s terms say anyone aged 18 or over can join. Gold Star costs ¥5,280 a year and Gold Star Executive ¥10,560, tax included. What identification a short-term visitor needs to join was not stated on the Costco Japan pages checked; ask at the membership counter.

Paying at Costco Japan

Section 5 of Costco Japan’s terms accepts “cash, Costco Shop Cards, Costco Global Cards (co-branded) and all Mastercard credit cards (some exceptions may apply)”.

• Mastercard credit card: listed; the terms do not address foreign-issued cards.
• Visa, American Express, JCB, debit cards: not named in the terms; do not rely on them.
• Cash: listed. See when banks close in Japan.
• Costco Shop Card: the Japanese Shop Card terms say it can be used only by members with a valid membership at warehouses and gas stations in Japan.

Bringing someone without a membership

Each member may bring up to two guests aged 18 or over, plus any number of children under 18. Only the member may buy. Costco Japan’s terms also cover a One-Day Pass (and Invitation Card) issued by Costco Japan: it is not a membership card, and anything bought with it is charged at the non-member price, 5% above the price displayed in the warehouse. The terms do not say how to get one, but a pass is invalid without an expiry date and issuing warehouse, or if bought from a reseller; a member may give a properly issued pass to a non-member free.

Warehouses you can reach by train or bus

Costco Japan’s warehouse finder listed 37 warehouses on 19 October 2026, all open 10:00–20:00 daily. Holidays normally follow those hours, though the finder notes that on holidays the opening time may change with crowding. The year-end exceptions are 31 December (7:00–18:00) and 1 January (closed). Every warehouse in the finder lists a food court. The access lines below are from each warehouse’s finder entry; none of the entries mentions a Costco shuttle bus, and a few give only a taxi ride from the nearest station.

Tokyo and around

Tamasakai, in Machida, is the only warehouse with a Tokyo address; the others below are in Chiba, Kanagawa and Saitama.

Osaka, Kobe and Kyoto

Izumi (Osaka) is the exception in this region: its finder entry gives only a 10-minute taxi ride from Izumi-Chuo Station on the Semboku Line.

Sapporo, Fukuoka, Hiroshima and Nagoya

Outside these tables, the finder entries for Maebashi, Gunma Meiwa and Kaminoyama give only a taxi ride from the nearest station. Hokkaido also has a warehouse in Ishikari, and Fukuoka Prefecture has Kitakyushu and Ogori; Okinawa’s is in Nanjo. Around Hiroshima, see Hiroshima and Miyajima in one day.

What to know before you shop

Tax-free. The Costco Japan pages listed in the sources made no mention of tax-free sales when checked on 19 October 2026. Read Japan tax-free shopping in 2026 for the rules.

Food court. All 37 warehouses in the finder list one, open 10:00–20:00. The Costco Japan pages checked do not publish the menu or prices. The sign photographed at Hamamatsu asks customers not to eat or drink on the sales floor.

Electronics. Check the packaging of electronics: the boxes below read “Console Language: Japanese only”.

Pack sizes. Costco sells many items in large packs; check what you can carry and store during your trip, and if you are moving on by train, read the shinkansen luggage rules before you add a large box to your bags.
