My main thing was that asian websites have more image-based content and their sentences and blocks of text look more blocky (due to uniformer characters and lack of spacing). I am not saying this is "shitty" - I am just saying that they have a different culture that makes these website the norm for them.
The rakuten looks quite busy, but at least it looks discoverable. I opened amazon and eBay and frankly they look hard to use since they hide some information.
But yeah the PS one looks more like a western page with a different language.
Also, if your ad blocker is on, you're probably not seeing these pages in their full glory.
JP Yahoo vs US Yahoo is a good contrast also, though the US site does smell of defeat as a portal (JP site is still dominant in Japan).
No no no... It's just that good web design is simply hard to find. No one is proud of these "asian websites". And it takes a while for updated good design practices to make it across the shore. Here is a decent site:

And for the record, a shitty "asian" one:
