When I open the OP's link, it shows me the B-3 priced at 3,931.88 USD, which is 2,981.25 GBP today.
As Mich486 says, Japan retail price equates to 2,622 GBP, to which you must add 22.5% import taxes and VAT (589.95 GBP) for a total of 3,211.95 GBP.
That's only 230.70 GBP extra markup. Not a big deal if you don't want to spend a couple of grand flying out to Japan. Not a big deal if you don't want the hassle of dealing with a Japanese website and international shipping if you have to send it back coz it doesn't fit. And RMC has to cover the overhead of having English speaking staff who can handle all of this.
If you can afford a 3000 GBP jacket, 200 GBP is nothing, surely.
Next case.
