Okay kiddo, so hajichi is a special tattoo that some women in Okinawa, Japan, get on their hands and arms. They use a needle to poke ink into their skin, which can hurt a little bit but they do it because it's a tradition that's been around for a long time.
The designs of the tattoos are like secret codes. They can represent things like the woman's family and hometown, or they can be symbols that only other women with hajichi would understand. The tattoos used to be a way for women to show that they were part of a group or community, and that they had their own language and culture that wasn't controlled by men.
But hajichi isn't as popular as it used to be, and now only a few women still get them. Some people think that's because of changes in society and culture, but others say that women aren't getting them because they don't want to deal with the pain or the negative stereotypes that come with being a tattooed woman.
