What does it mean this kanji from Kong movie?


sorry, I am curious about what does this Japanese symbol represents. It's from
the latest Kong's movie, Skull Island , and I believe it is taken from the
fight airplane of a Japanese pilot during second world war.

It is not a Japanese symbol or character including Katakana, Hiragana and
Kanji. I think that the movie producer wanted to express Japanese exoticism
and independently designed the symbol or character similar to Japanese
imaginary symbol or character.
