Hondo-Cit

The island nation of Japan exists in the world of judge dredd and has become a giant mega-city called Hondo Cit. Many of the stereotypes of today's Japan are present in Hondo Cit, like the institutional organized crime, the degradation of women, the obsessive cleanliness, the pop-culture, but this has been mixed with much more traditional tropes like samurai, ritual suicide, martial arts and medieval weaponry.

The occasional giant robot or reptile makes an appearance too.

Hondo cit is also famed for its high tech gadgets and weapons, much of which ends up on the black market in other mega-cities.

It must be mentioned that the Hondo cit judges are issued Tendo Staves and Hover Bikes, which actually work as they're supposed to.

Stories set in Hondo city have the Manga feel without the "Anatomically Incorrect Schoolgirls". I approve.
