If you're after an awesome proposal or wedding jewelry set from Japan, it's hard to argue with Pokemon wedding rings with Pokeball ring cases, but for those with quirkier tastes, Japanese capsule toy maker Kitan Club may have just the thing. Riceball ring and case sets!

Kitan Club has a reputation for giving many of their capsule toys a cute food-related theme, most recently seen with their adorable "Hamster and Egg Ham and Egg" series. Now they've set their sights on perhaps Japan's most popular eat-on-the-run snack in onigiri, or riceballs. As a clever twist, these capsule toys don't have a traditional capsule--instead the "capsule" is the riceball itself, with the inside being a surprise ring modeled after popular onigiri fillings.

Ikura (salmon roe)

Mentaiko (spicy cod roe)

Grilled fish

Ume (Japanese pickled plum)

Konbu (kelp)

The onigiri ring and case sets are currently available where all Kitan Club capsules are available, as well as in surprise packs at toy stores for 300 yen.
