The 37th Japan National Ninja Championships were held on 11 October 2020 at the Koka Ninja Village in Shiga, Japan.

86 ninjas from around Japan competed on the following 5 ninja techniques/skills:
*... in the above video.

1. 手裏剣(Shuriken)*
2. 石垣&塀越え(Ishigaki&Horigoe)* - cross over the stone wall & fence
3. 塀飛び(Horitobi) - jumping over the fence
4. 水上走り(Suijohashiri/Suijobashiri)* - running on the water
5. 水蜘蛛(Mizugumo)* - means 'water spider'; a water crossing device

What is 3. Horitobi like? I've found a video on Horitobi - jumping over the fence at the 32nd Japan National Ninja Championships in 2015.
