This place had some pretty cool matcha items for sale. I found and bought some matcha butter which I'm looking forward to trying.
There are two options of matcha soft cream: mild and rich. We went rich and weren’t disappointed: intense matcha taste, and not too sweet. Grab yours and head to the temples. They also offer other matcha sweets, like matcha warabi mochi, which we didn’t try. Service is a bit slow.
Ice cream + warabi Mochi are both rich taste of matcha
2nd reason to be in Narita.
Sorry for the dirty photo.
