MLB official “Happi” is sold in Japan.
I think that the combination of MLB and the tradition of Japan is interesting. However, I do not want to buy it. I do not hear the story that this sells well.
“Happi” is a kind of the kimono of Japan often puts on in the place where the festival and the sports watching, etc. which are lively and happy.
However, it is a coincidence that “Happi” and “Happy” look like, and it is unrelated.
