I remember having fantastic home-cooked Japanese curry when I was in Osaka. It is a bit like the best casserole you've ever had, though, so I see the Brit-link....Yeah kinda, but this was at Central World Mall and the price discrepancies aren't always quite what you'd think for non-Thai food. Mostly I ate Thai style curry from street guys or the cheaper food courts.
Yeah fair enough, I do just kinda feel that Japanese curry can be largely replicated by buying a katsu sauce from the supermarket and a trip to the chicken shop. Obviously it makes sense that we've taken to Katsu, but generally Brits have better access to cooking facilities than students in Asia and can knock their own simple grub together. Admittedly we've largely forsaken deep fat fryers thanks to public safety announcements during the 1980s, but most of those dishes can be replicated with relative ease.
