My Aunty returned last week from a 2 week visit back to Tokyo. She and my Uncle and their family finally migrated here. They were waiting for their visas for over 20 years! It's pretty much been a lifelong goal for their 4 children (my cousins).
She brought me this "Tokyo Banana" as omiyage (gift or souvenir). They gave me this before when they visited Honolulu. It's a tasty packaged cake with a banana cream filling. It is something like a Banana Flavored Twinkie, but much higher in quality. Unlike the Banana Flavored Twinkie, the Tokyo Banana's cake doesn't have a strong banana taste. The cake is a simple yellow cake much like the normal Twinkie. The Tokyo Banana's banana filling is where the banana taste is present. It's a consistency of like a banana puree and tastes like it is real banana. I don't know if it is 100% banana puree of some sort, but it definitely isn't like a banana flavored cream in a Twinkie.
If you like bananas and cakes or Twinkie type snacks, try this out some time!
