Do you know about otaku?
Otaku is a Japanese term for people with obsessive interests, commonly the anime, video games and manga fandom.
Nowadays Japanese anime is popular over the world such as One Piece, Dragon Ball, Gundam, Evangelion, Attack on Titan etc...
So otaku culture became world famous and many otaku people over the world come to Japan.
If you are otaku and come to Osaka, you should visit "Den-Den Town"
"Den-Den Town," Nipponbashi is known for its many shops which specialize in furniture, tools, and "otaku" interests such as electronics, animation, manga, and collectibles. Nipponbashi is often compared to Akihabara Electric Town, its equivalent (in terms of focus) in Tokyo.
