Gakken Stayful Launches Collectible Mojojojo Character Bath Bombs for Fans

Gakken Stayful released its new Mojojojo Mascot Bath Bombs on March 24, 2026, bringing character-shaped bath fizzies into a product category that Japan has long made its own. The bath bombs retail for 594 yen, putting them squarely in impulse-buy territory for collectors and gift shoppers alike.

The character-shaped bombs feature the cute Mojojojo mascots, pitched at both collectors and bath lovers. Gakken Stayful, the stationery and lifestyle goods arm of the Gakken group, has built Mojojojo into a recognizable mascot brand, and the bath bomb line extends that character identity into a functional everyday product. It's a smart play: bath fizzies are already a natural fit for novelty packaging in Japan, where character-goods culture runs deep.

The bombs are available at stationery and goods stores across Japan as well as through the official Gakken Stayful online shop. They can also be found on the Rakuten official store and the Gakken Stayful Yahoo! Shop, which covers most of the major Japanese e-commerce channels and makes them easy to track down whether you're shopping in-person in Tokyo or ordering from abroad.

At 594 yen a piece, these are priced to collect multiples, and that's clearly intentional. Character bath bombs in Japan have a well-established collector dynamic, with buyers picking up extras to display or gift rather than purely to use. The Mojojojo line fits that pattern precisely: shaped to show off the mascot design, accessible enough to buy a handful at once, and recognizable enough to work as a gift for anyone already familiar with the character.

For further details and product updates, fans can check the official Instagram page or the Gakken Stayful website. Given the 594 yen price point and the character's existing fanbase, these are likely to move fast at retail before restocks catch up.
