Hello! This is just a quick list of mantises found in Japan. I will make it better after some time passes. Some of this stuff I list might be wrong. I saw this great post of Mantises of Japan here: http://m.blog.naver.com/eldkfnrk1/220618816567

==Hymenopodidae==
Acromantis japonica (found in mountains. I don't know if they are found at lower elevations. The Acro in this genus's name might mean high because they live in mountains?)
Acromantis australis (in Kyushu)
Acromantis satsumensis
==Mantidae==
Mantinae
Tribe: Mantini
Statilia maculata maculata
Statilia nemoralis
Statilia parva (in Okinawa)
Unknown species of Statilia from Okinawa
Statilia hyalina (doubtful if it's a real species; might just be a lighter color variant of one of Statilia listed above)
Mantis religiosa sinica (M. religiosa go up north to Hokkaido in Japan, along with the Tenodera sinensis(?))
Tribe: Polyspilotini
Tenodera sinensis or Tenodera aridifolia? Or both species? I am leaning toward Tenodera sinensis at least being the common ones in much of Japan, since they are so big and thick.
Tenodera angustipennis
Unknown species of Tenodera in Okinawa (Big in size and skinny)
Tribe: Paramantini
Hierodula patellifera (lives in trees and maybe bushes)
Hierodula venosa (non-native found in Nagoya and Tokyo)
Rhombodera valida (from this website said to be in Japan)
Amelinae
Ameles nawai
Orthoderinae
Orthodera burmeister (in Okinawa)
