So JCB controls the exchange rate in this case, not Discover? Is it the same case for UnionPay in China? We've had discussions on here before that Discover and AmEx typically have poorer exchange rates for non-pegged currencies, but I wouldn't expect it to be 11% higher.
It's not an issue of DCC, but if that's the exchange rate it's 3x what you'd typically see for a DCC markup. With exchange rates this bad I too would rather take the DCC hit. (...even though I've never seen DCC in Japan.)

Please report back, but is it also possible to show the UNIQLO receipt? I'm curious to see the posted transaction amount.
