Id badge - help

[garde]

Hello is there anyone can help me identify the helmet badge in this photo?

Is it star, anchor, sakura anchor, round snlf badge or somekind of badge made by the indonesian?
This helmet was worn by the indonesian guerrilla during the battle of surabaya in 1945.
Thank you in advance.
