There are a few other competitors in the market, but none of them really come close to the Kasugai either flavor- or texture-wise. Plus, each pack comes with its own description, written in quirky Japanese-English idioms. Like this, from the strawberry bag:
Kasugai's strawbery gummy, made from fresh strawberry juice is a very delicious gummy. Please have a fun time with this strawberry gummy.
Thank you, I will!
Do you guys have a favorite flavor of Japanese gummy?
