Taiyaki are Japanese fish-shaped (sea bream, to be exact) cakes usually filled with red bean paste, but custard and chocolate varieties are also popular. Sweets maker Meito offers a mochi monaka wafer version of taiyaki filled with an airy mousse chocolate called Puku Puku Taiyaki, and it's new flavor seems to be a taiyaki first: salty watermelon!

The new release sandwiches pink salty watermelon-flavored chocolate in between two green monaka wafers for a very reasonable 60 yen treat.
