In Japan, tattoo is the symbol of Japanese mafia (yakuza).
Decent people never try to make tattoo in Japan.
And police would not allow people with tattoo to swim in a pool or bathe in a spring.
The mayor of Osaka city doesn't allow people with tattoo to word at the city office.

Old days, a round tattoo in one's arm was the proof that he has a criminal record.

Now in younger generations think not much about tattoo, but old Japanese decent people hate to see tattoo.

You may do tattoo, but I strongly advise you not to show it to Japanese people.

Hope this helps.
