It's because of the association between tattoos and a mafia-like group called the yakuza - which has operated in Japan for hundreds of years.
"The tattoos are crucial to yakuza members," according to Anton.
They're instead a "very personal depiction" of a scene from the yakuza member's life, or something symbolically important to them - which is meant to show people the attributes that person is known for.
'It's about respect'Anton says the yakuza keep their tattoos covered up in public because they're very aware that tattoos are frowned upon.
So they would say in a very opaque way 'We don't allow tattoos', because hundreds of years ago only yakuza people had tattoos."
