There is a discussion in the comments regarding the 934Ku "Rufe" with the inazuma (lightning) on the fuselage. There is a series of good photos in the fairly recently published "Nankai no Umiwashi" by Dai Nippon Kaiga, available from our on-line bookstore here.
Unfortunately I can't scan the photo without destroyng my copy so instead I'll post the artwork by Nishikawa Yoshinobu which is accurate in every respect except perhaps the hues of each color.
As you can see the tail marking is in yellow, the fuselage hinomaru have a darker surround, the wing top hinomaru have a white surround, the wing undersurface hinomaru have no surround.
It has very narrow IFF stripes on the wing leading edges.
