I'm looking for different Japanese flavored Kit Kats Especially the "cherry blossom & Sake" is there a big variety on chocolate would I have luck finding this or some here?

Amazon has Sakura sake Kit Kats if you check. If you can't wait, Tokyo Central had a large selection of Kit Kats and other chocolates there last time I went two weeks ago. It would be best to call them and ask. Daiso is another good place to go. I think Mistuwa may also have it. Otherwise do a search for the flavors you want. Some online stores in Japan will skip them for you

The last time I was there they didn't have the matcha flavor anymore. I've never seen those other flavors there either.

Yes, also Amazon has it to.

There or Daiso would be the best place to look.
