This place is as genuine as it gets! I came here one evening with my bear after seeing their post on instagram, and it blew me away.
Having been to Japan, I have tried the most authentic japanese daifuku that I could find. The mochi is very similar in texture and taste - it is not overly sweet like the supermarket ones.
I highly recommend this place if you want to try something different. At a price of $2.50 a piece, I for one actually think its worth it. The person working at the store took her time to explain all the different flavors and recommended popular ones (such as sakura). She also explained that they import their mochi from Japan, which speaks volumes for itself.
I ended up purchasing a package of 4 for my family to try. I highly recommend the houjicha flavor!
Overall a very pleasant experience, would come again!
