Akihabara is the place to be if you love Electronics, Gadgets and Anime stuff. Another thing to enjoy are Itasha’s which are often parked or driving around Akihabara. Itasha’s are cars, decorated with stickers or painted with Anime or Game characters. You don’t see this often outside of Japan, which makes it exciting to see for tourists. Most Itasha owners are ok with taking photos of their car, but it’s always polite to ask first.
There are often Itasha events around Tokyo where you can make lots of photos and enjoy all kind of Itasha!
