does the Japanese Occupation 10 Pesos has a watermark?

so i accidentally found out that the 1942 Japanese Occupation 10 Pesos has a watermark, its this Flower looking pattern scattered across the banknote.. is this an actual thing we don’t know about or somethin? ive also tried the same on other pieces of my jim notes, they also had the same flower pattern like watermark. and some of it don’t have the flower pattern watermark and some also had the watermark but its faint to the point its less visible

first image for example that doesnt have a watermark 

The 500 pesos page states that it has a banana tree N#224518

Here is a picture I took in 2021, I probably wanted to add it but forgot about it somehow 😅

They look like stylized clouds, the kiri leave pattern like on other Japanese notes of that era or something similar.

It's Intresting learning further more about Japanese Occupation money ha!, I also wanted to add the watermark to its page but I got lazy so I'll maybe do it sooner if I can. Also thanks for maybe helping me know that they actually had these watermarks.
