No membership needed!
Try Costco for a day with the One-Day Pass
If you’ve seen this ad, you can shop at Costco for a full day without a membership during the campaign. Join the same day and unlock bonus perks. Here’s exactly how it works — steps, conditions and annual fees.
Curious about Costco but not ready to pay the annual fee just to look around? Good news: until Sunday, August 30, 2026, Costco’s “One-Day Special Invitation” lets non-members shop for a full day — no membership required. Just show this campaign screen at the membership counter to get in, and if you like it, you can join on the spot. Sign up together with a friend and you’ll each get a ¥1,000 coupon plus more. Below, we break down how to use it, who’s eligible, the annual fees and the fine print.
What is the One-Day Special Invitation?
Costco is normally a members-only warehouse store — only members who pay the annual fee can enter. This campaign, the “One-Day Special Invitation” (One Day Shopping Pass), opens the doors to non-members for a limited time.
It’s wonderfully simple: just show the campaign ad screen at Costco’s Membership Counter, and you can enter and shop for that one day without signing up. It’s perfect if you want to look inside before deciding whether to become a member. The campaign runs until Sunday, August 30, 2026.
Why Costco is worth it
Costco’s policy is to keep offering carefully selected, high-quality products from around the world at the lowest possible prices. Shopping there feels like a treasure hunt you won’t find anywhere else.
Bulk sizes, low prices
From groceries and household items to jewelry, electronics and clothing — large packs at the lowest possible prices. Buying in bulk lowers your unit cost.
Kirkland Signature
Costco’s own private brand — nuts, water, household goods and more. High quality at outstanding value, and hugely popular.
Food Court
The famous ~20cm hot dog, pizza and more — a fun part of every visit, and a great break after exploring the aisles.
Two-part guarantee
Not satisfied with your membership? Fee refunded. Not happy with a product? Purchase refunded. Try it with low risk.
There are also specialty areas: optical (glasses, sunglasses, contacts), hearing aids, pharmacy, a tire center, jewelry and more. Just walking the floor is an experience in itself.
How it works on the day (3 steps)
- Experience the floor with the One-Day Invitation. At the Membership Counter near the exit, show the campaign ad screen to complete the process. First-timers can relax — it’s easy.
- Take in the huge warehouse. With products stacked to the ceiling, the floor feels like a treasure hunt — you never know what’s in the next aisle.
- Like it? Join the same day. Signing up on your visit day is the best value. Come with a friend for even more perks (below).
Sign up with a friend for extra perks
If you and a friend both sign up as new members on your visit, you’ll receive the “Refer a Friend” campaign perks.
¥1,000 coupon for each of you
When you and your friend each newly join, you each get a ¥1,000 coupon usable on purchases of ¥10,000 or more.
Exclusive shopping bag
You’ll also get a not-for-sale, specially designed Costco shopping bag — big enough for bulk groceries and a shopping essential.
Membership types & annual fees
If you decide to join, the annual fees are as follows (tax included). First, find the plan that fits you.
| Membership | For | Annual fee (incl. tax) |
|---|---|---|
| Gold Star | Individuals | ¥5,280 |
| Business | Self-employed / companies | ¥5,280 |
| Executive | Upgraded membership | ¥10,560 |
That works out to about ¥440/month for Gold Star / Business and about ¥880/month for Executive. Executive members get exclusive services and coupons, and you can upgrade from Business or Gold Star. Anyone 18+ living at the same address as the primary member can get one free household card, plus access to the members’ newsletter and online shopping.
Eligibility & things to note
Conditions for the One-Day Invitation can differ each time it runs. Here are the general terms and cautions. Always check the official Costco page for the conditions that actually apply.
- A photo ID showing your current address is required to enter (driver’s license, My Number card, etc.).
- Households that were previously Costco members, or that have used a one-day invitation before, may not be eligible (typically for first-time households only, once per household).
- Paying as a non-member usually adds a 5% surcharge to listed prices — but if you join the same day, that 5% is generally refunded.
- You can usually bring up to 2 guests aged 18+ (children under 18 are often not counted).
- Fees, perks and conditions may change, and opening hours may change without notice.
