Please note that the photo used to illustrate Japanese Unit # 372 is incorrect; the picture used shows the second version, the N1K2 which has been correctly used for Unit 376.
The N1K1 had the wings mounted much higher on the fuselage, betraying the aircraft's float plane ancestry, so that the long undercarriage legs needed to clear the huge propellor from striking the ground tended to buckle, snap or not function properly. The N1K2 had the wing repositioned at the bottom of the fuselage.
I attach a link to a not ideal photo, cluttered up by ground crew:
