Huh. Weird. In twenty years in & out of Japan and seven years living there, I can't recall seeing Rimowa more than a handful of times. LV, however....

Personally, seeing as I don't tend to check luggage and carry on simply doesn't take the battering that checked luggage can/will, I don't see the value: I spend ~$50 for something like a Lucas 21 inch carry on and it lasts 5-10 years easily enough. The cost/value ratio simply isn't there for spending large amounts of money. $400+ for something that will last 20-30 years is still a bad deal IMO. Obviously, YMMV & it's your money so have at it.
