Bikkura Tamago Surprise Bath Bomb

Bikkura Tamago is a popular Japanese bath product that combines a bath bomb with a collectible figure. Produced by Bandai, this item is widely known in Japan for its “surprise” concept. Each unit contains a dissolvable bath ball with a hidden figure inside, which appears once the product fully dissolves in water.

Product Concept

The name “Bikkura Tamago” roughly translates to “surprise egg.” The idea centers on the combination of a bath experience and a collectible toy. When placed in water, the bath bomb fizzes and gradually dissolves. As a result, a small figure emerges from inside the ball.

The figure inside is random, which adds a collectible element. Therefore, users cannot choose which character they receive. This blind-box style makes the product especially popular among collectors and fans of Japanese merchandise.

Pokémon Version

The Pokémon versions of Bikkura Tamago feature characters from the Pokémon franchise. Each release usually includes a set of several possible figures. For example, a series may contain around five different characters to collect.

The figures are typically small, around 3 cm in size, and designed in a simplified or chibi style. In addition, the bath water may change color during use, which enhances the experience.

Because the contents are random, collecting a full set often requires multiple purchases. As a result, these products appeal both to children and adult collectors.

Materials and Use

Bikkura Tamago products are made using standard bath bomb ingredients such as sodium bicarbonate and citric acid. These components create the fizzing reaction when placed in water.

The product is intended for bath use only. It should not be ingested, and users should follow the safety instructions included with each item.

A Popular Japanese Collectible

Bikkura Tamago remains a long-running product line in Japan, with releases continuing since the early 2000s.

Because of its mix of surprise mechanics, collectible figures, and licensed themes like Pokémon, it has become a recognizable item in Japanese pop culture and merchandising.
