Tokyo Banana is a famous Tokyo snack, and is one of the most popular souvenir gifts purchased when people visit the city. It is a small, banana-shaped sponge cake filled with creamy banana custard. Other flavors feature hints of honey, coffee milk, or maple in the custard. These are often decorated to look like cute little bears, otters, and pandas.
Like Kit Kats, Tokyo Bananas are used as omiyage, as some varieties can only be found at certain locations, like major Japanese airports.
Though this Japanese cake is incredibly popular, it can be difficult to find outside of Japan because its fresh custard filling requires refrigerated shipping and it has a very short shelf-life.
One way to get a taste of this iconic snack is with Kit Kats! There was actually a crossover between Tokyo Banana and Kit Kats, where both banana and banana caramel Kit Kats were made.
