Walking through Tokyo Station it is hard to miss the booths selling Tokyo Banana. It’s a very omiyage. I’ve received it as a gift twice in the last few months.
The banana-shaped cakes are individually wrapped.
It’s a soft sponge cake filled with a banana cream custard.
New flavors are introduced from time to time. Currently Tokyo Banana is celebrating their 20th anniversary and are offering a caramel banana version. You can see a list of their many different sweets here.
