In Tokyo, Accuphase is all over the place. Even in the huge electronics retail chains. I didn't see many integrated amplifiers, however.
Interestingly, in 2011, Accuphase launched the wonderful T-1100 FM tuner. A follow up to the excellent T-1000 tuner. Some consider the T-1100 to be the very best tuner ever made. Sounds absolutely wonderful.

US new price is probably north of $5k now but I have no idea. A couple of years ago, used Japanese T-1100 and T-1000 sold pretty cheap but prices seem to have risen. Grey market units can be imported from Japan to Europe & the US. However, you would be stuck with Japanese tuning scheme (Accuphase told me a few years ago that they will not modify JDM units, although maybe that has changed or someone has figured out how to do that).
There are still some fantastic classical and college FM radio stations in Japan, Europe and the US. If a $5k Accuphase is a bit out of the budget, there are plenty of 1970s FM tuners that can be purchased and aligned by a good tech for less than $500.
Apologies for the tangent.
Out of curiosity, what is a “Japanese tuning scheme”? Somehow adapting to smaller room sizes and the typical construction of Japanese abodes?
