No, it's really not fine at all. It's not just websites, it's electronic devices in general. The UIs are very complicated with every conceivable function right in your face. My Japanese girlfriend even complains about it. Things like washing machines and microwave ovens even are needlessly complicated to use. (Younger) Japanese people love western web sites/services such as Instagram, Twitter, Google Maps, etc., and don't insist on a Japanese UI-style version of any of these.

Don't even get me started on how well Japanese websites handle non-traditional-Japanese names, or how banking apps that supposedly support English actually display most text and dialog buttons in Japanese.

There's a lot of great things about Japan, but the UX/UI here is absolutely terrible.
