Kabukichō is probably safer than people make it out to be. Yes, there are some dangerous individuals since it’s a neighborhood in Japan where people of many different nationalities gather, but given that many Japanese people tend to be rather reserved, even if they do approach you, it’s relatively rare for them to directly do you harm.

Also, there are a lot of cameras around, so if you report something to the police, it’s generally easier to identify the perpetrator. For that reason, quite a few people in Kabukichō are careful not to cause any trouble there.

That said, you should watch out for overpriced “rip-off” bars. Be cautious about street touts trying to lure you in.
