Diagnosis. Tachinus (Tachinus) japonicus can be distinguished from other members of the subgenus Tachinus from Japan by the combination of the following characters: body large, almost dark brown; male tergite VIII with four lobes, outer lobes undefinite; female sternite VIII with three lobes, each lobe broad and separated by very narrow incisions. This species is similar to T. (Tachinus) obesus , but can be distinguished by slenderer parameres of aedeagus and broader lobes of female tergite VIII. For detailed redescription, see LI (1995a: 64).

Biology. This species is commonly found around mushrooms in montane zones.

Distribution. Japan (Hokkaido, Honshu incl. Sado-ga- -shima Is., Awa-shima Is., Oki Isls., Shikoku, Kyushu). This species is distributed in montane to subalpine zones in mainland Japan.

Remarks. Tachinus japonicus and T. obesus were confused before ITO (1993) explained the difference between these species.
