Hi, from what I could find the original title should maybe be changed to Russian. The movie was made in Japan, but the voice cast is mostly Russian. No sites lists the Japanese title as the original one. So with what I could find now we can stay with the current original title or add the Russian one. What is the best option for you?

Hi, indeed it's a co-production - I thought Japanese was best as the director is Japanese, and Wikipedia lists the Japanese title first, however I guess it's difficult to choose!

No objections for the Russian title as the original:

Пе́рвый отря́д

At this point I would add the Japanese title as an "Alternative Original Title".

Thanks!

I changed the original title to the Russian one and added the English as the translated English title. Thanks.
