Chrome auto translates into decent Engrish and converts Yen into USD, boiiiiii. Scams, you say? I figure it's not as airtight as purchasing from domestic eBay, but it's a pretty well established site. I'd say it's closet to purchasing from brick and mortar stores via Amazon. Sure, you could get scammed but don't those stores face losing their ability to do business if they freely scam several buyers?
Also, I've noticed that one seller I've been watching on eBay crossposts his Rakuten sales, albeit at much higher prices. Everyone thinks Japanese brands are some sort of unicorn, but they're plentiful and affordable over there. Shipping is the real bitch, though. EMS is fast, and expensive.
