Unfortunately I cannot make out the wing venation because the essential part is blotted out by the darker background. Any chance it might be more clearly visible in the original image?
Further, it reminds me of
Trichopeza longicornis of the Empididae but I do not know if that species occurs in Japan or even related genera/species.
