This design was inspired by an old song that I like. It's played a lot on my twitch channel. It's just nice to look at the moon with your boys after a war.
The song is called:
The song of the South Manchuria Railway
(南満州鉄道愛唱歌)
It's an old Gunka (軍歌) or military song written by Imperial Japan long ago. The song I believe was made around 1904-1905.
Regardless of history, it's a nice song to listen to, and you'll hear it on my twitch a lot.
