In my experience Rakuten represents a more extreme example and isn't representative of "modern" Japanese UI/UX as a whole. Companies started in the last 10 years are abandoning what we might deem as a cluttered aesthetic and moving towards something which wouldn't look out of place in the west. In fact my current company ended up going with the same UI when they launched in the US with minimal modifications.
