For me, the OP looks like a typical nominate
cristatus, the combination of warmer, rufous-toned cap and rump/utc's, narrow white supercilium and apparent reduced warm tones to underparts are compelling. Japanese Brown ssp.
superciliosus is typified by more uniform intense rufous-toned upperparts
i.e with little or no contrast in head and rump, a broad white supercilum including forehead and more saturated warm buff underparts with a white throat.
Japanese Brown has by far the most restricted range of the 4 taxa (S Sakhalin, C & N Japan) appears to be in serious decline, in Japan at least, as a result of habitat loss.
