This is not a very interesting picture and therefore I have used Photoshop to play around the colour to make it look more interesting. Indeed the place itself is not too interesting either as it’s just a small cape facing the sea. What makes it interesting, or I should say, famous, is its location: It’s the easternmost point in Japan.
Geographically it actually isn’t the easternmost point in Japan. Even if we don’t count the disputed islands in the north between Russia and Japan, there is still another Japanese small island lying to the east of Cape Nosappu. Yet that island is inaccessible by public and so Cape Nosappu is indeed the publicly accessible easternmost point.
There are two things that you can see a lot around this small area. The first one is lots of buildings claiming to be “The Eastern XXX in Japan” where XXX can be a school, a restaurant or even a police station. Indeed we read that in some souvenir shops you can buy “certificate” of being to Japan’s easternmost point (we did not see any though).
The other things you can see are monuments or plaques about the dispute between Russia and Japan on the northern islands. There is also a museum there about the history of the dispute.
