I know it's a weird question, but I was recently watching Pornographer (2018) and I think they were both filmed in the same town/city.

Ive looked literally everywhere and I cant find anything on filming locations but ive asked around and i'll let you know if i find anything.

From what i've read, UK was mostly filmed in Uenohara and Tokyo.

The shrine is Ushikurajinja, the river Katsuragawa, in Uenohara. The family house, university, café-théâtre (season 1) and the shops they visit during their "date" (season 2) are in Tokyo.

Pornographer however was filmed in Hino (someone did an amazing job here).

They're not that far (in distance, but also from an architecture and history's point of view) from each other, but it's not the same cities. :)
