Leave it off if you want. German crosses, IMHO, are OK.

Japanese markings: as far as I'm concerned, copy them 100%. I seriously
doubt there are going be many people concerned about it, other than the
PC types who think the Japanese were "victims" because of the the nukes.
For them, I give a eye roll.

Some things, like the swastikas, can offend a race of people, even if
its historically correct, becasue of its connections.

OTOH, I know of no markings from the Japanese that would be offensive.
The rising sun, maybe, but I doubt it.

I suppose China, Burma, Korea and the like would not be a good place
to fly your airplane if it has Japanese markings.
