I'll keep it short: I bought chop sticks, sake cups, good luck charms, candies, toys ..... the list goes on. But your name as a kanji is the best souvenir which I could get!
And it is also suited for a dear friend/your girlfriend/wife, even if she is not here.
A kanji name is based on your original name, but it also incorporates various hobbies, skills and personality traits of the person. To simplify it: let's say you are Steven, and you like hiking (and various other hobbies/traits). The staff will look for syllables based on your name (St- for example) and your trait. So the first kanji of your name is St- with the meaning of mountain for example.
It was easily the best experience in Tokyo! Don't miss out!
PS: the staff is super friendly!
Purchased an authentic Japanese scroll with my name in Kanji which was awesome. So awesome we came back a second time to get more as presents.
I'd like to add the atmosphere was traditional and relaxing and we were able to have a few laughs and get some cultural insight into Japan. I have been learning Japanese and Minami made it easy for me to practice, with her knowledge of both Japanese and English. We finished by getting a selfie with the staff so all in all MUST VISIT.
My wife and I took a guided tour of Asakusa with Rena from Kanji house and it was an awesome experience. She was genuinely interested in conversing with us as well as telling us all about Senso-ji temple. She gave us a choice of several types of food we would like to try on our way through the area as well.
We would have gladly paid for just the tour and the lovely conversation but the amazing personal touch of the calligraphy just made it so memorable. Rena sat with us personally for quite a while asking my wife and I about one another before she chose the kanji that best represented us. And of course the calligraphy was a work of art.
We would recommend Kanji House to absolutely everyone visiting Tokyo! Rena was an amazing hostess and based on the reviews here I can assume everyone else at Kanji House is too! No matter your age this can't be missed. Easily one of the highlights of our trip.
And if you meet Rena don't forget to ask her about the Tanuki war!
