What about a bit of Japanese green tea with the senbei you just toasted?
As an option for the senbei toasting activity, you can enjoy some Matcha tea at the shop, although a simple version. Not only Matcha tea but barley tea and regular green tea are available.
Attention. It is not a traditional tea ceremony preparation. You won’t sit on tatami and wear a kimono. You will just be seated at the shop and have a taste of Matcha tea to just give you a general idea.
If you wish to do this, let us know when applying for the senbei toasting activity that you want also want to have the Japanese tea option.
