I found out about the Akaviri, who live in a continent just east of Tamriel called Akavir. I heard they had something to do with the Blades, a group of warriors who used to fight dragons and protect the Emperor. When I looked up the continent, it had provinces with Japanese names such as Tang Mo. I also looked up the people themselves and they look like Japanese samurai. Are the Akavir really like the Japanses people or not?
While there isn't any official statement supporting this, the Skyrim wiki states that Akaviri people resemble China and Japan.
On a personal note, I checked the names and pictures of Akaviri NPCs and they really do look/sound like Japanese people/places.
Also, the pictures of Tang Mos resemble Japanese macaques.
