FamilyMart’s “Buy One, Get One Free” Festival is Back! A Complete Guide to Eligible Products

FamilyMart, one of Japan’s leading konbini chains, has launched its highly popular “Buy One, Get One Free” campaign again. This is an incredible deal where purchasing one eligible item gets you a voucher printed on your receipt for a free item in the same category, redeemable at a later date.

The campaign is simple, but there are a few details to note. First, purchase an eligible item between Tuesday, January 6, 2026, and Monday, January 12. A voucher for a free item will be printed on your receipt. This voucher cannot be used immediately; it must be redeemed for an eligible product during the redemption period the following week, from 7:00 AM on Tuesday, January 13, to Monday, January 19. Be careful not to accidentally throw away your receipt!

Now, let’s take a closer look at the products eligible for this campaign.

[FamilyMart Exclusive] Asahi Wilkinson Tansan Extra

First up is the “Wilkinson Tansan Extra,” available exclusively at FamilyMart. “Tansan” is the term for sparkling water, a widely popular beverage in Japanese konbini and supermarkets. When you buy either the Pink Grapefruit or Grape flavor, you’ll receive a voucher for another free bottle of either flavor. This is a great chance to get two bottles of this popular sparkling water, which pairs well with any meal, for the price of one.

Coca-Cola Georgia Black & Caffè Latte

“Georgia,” one of the brands that has been a driving force in Japan’s canned coffee culture, is also part of the campaign. Purchase a 500ml bottle of the crisp-tasting “Georgia Black” or the smooth “Georgia Caffè Latte” and receive a free voucher for the same item. It’s a great way to stock up on coffee, an essential for refreshing breaks during the workday. Please note that products sold hot are not eligible for this offer.

Megmilk Snow Brand Megumi Gasseri SP Strain Yogurt Drink

Products like this, designated as “Foods with Function Claims,” are popular among health-conscious consumers in Japan. This yogurt drink, containing “Gasseri SP strain,” is an item many people include in their daily health routine. Since you can buy one and get another one free, it’s a perfect chance for those who want to make it a regular habit.

Toyo Suisan Hot Wonton

“Hot Wonton” instant soup, perfect for a light snack or for warming up on a cold day, is also on the list. Purchase either the “Whole Chicken and Egg Soup with Kelp Umami” or the classic “Soy Sauce Flavor” and get a voucher for one “Wonton Soy Sauce Flavor,” “Wonton Tonkotsu,” or “Wonton Seafood Soup Flavor.” It’s great that you can pick a different flavor for your free item. There’s also an interesting regional touch: in the Hokkaido area only, “Soup Curry Wonton” is also included as a redemption option.

Morinaga Ramune Bar

The “Ramune Bar” is an ice cream bar that recreates the flavor of “Ramune,” a classic soda pop from Japanese summer festivals. It’s a long-loved treat known for its refreshing soda flavor and the crunchy bits of Ramune candy scattered within. You can get one free when you buy one, so why not take this opportunity to try a nostalgic taste of Japan?
