Where to get tattoo in Japan?

Who are the best tattoo artist and where can I find them? Preferably in Tokyo or Kyoto.

From what I understand, the best Japanese style tattoo artists have waiting lists that are years long, and some require referrals to even get an appointment. So you may need to do a lot more research depending on what you are looking for.

I have not been to any, but these are the ones that usually get recommended here and on other forums.

The artisits Gotch and Gakkin at http://www.harizanmai.jp/
in Kyoto are often recommended. You can see galleries of their work on the website. Google them for some more information/ recommendations. You will probably need to make a booking to see them, so I suggest you do that well in advance, either via e-mail or by phoning them. Also try and determine if what you want can be done in one sitting or not.

Chopstick Tattoo in Osaka

are another popular choice and have been around for a long time. Again, google is your friend.

Other options include Finleine in Yokohama.

or Rat Tattoo in Tokyo.

Good luck!
