SASSEN(サッセン)イベント in 秋葉原 Akihabara

What is SASSEN
[Image 3

All you need is a smartphone.
The tools are only a 70 cm long polyethylene foam sword “SASSEN Katana” with built-in sensors and a smartphone (tablet). If you hit the body other than the head, it will become one, and the application will perform the hit judgment.

The SASSEN sword was patented on December 22, 2016 (No. 6062592 “Sports Engagement Device”)
The winner will be either “best two” or “the one with the highest number of runs within the 60 seconds of competition time”. Attacking is up to 5 swings (5 strokes) per person, and after that you can only defend, so it also has the aspect of a brain battle to think about how to make the most of the limited attack opportunities.

It was born from the desire to create an event that everyone who participates, spectates, and supports can understand and enjoy.

Since I only use the SASSEN sword, it doesn’t interfere with cosplays such as Annihilation Blade and STARWARS. Parents are also attracted to the “appearance”, such as holding a shining sword and taking pictures. A lifelong sport that can be enjoyed by men and women of all ages [Image 8

The rules are simple, so everyone from children to the elderly can participate. Because it can be enjoyed regardless of age, gender, or disability, it is a new sport in which disabled and able-bodied people can compete under the same rules and conditions.
Nationwide expansion and competitive population

Further evolution of competition precision and expansion of the competition population. Even now, development is underway with the aim of creating a Japanese lightsaber.

SASSEN is a non-contact sport that can be done even during the COVID-19 pandemic, which is a major reason why it continues to expand despite the coronavirus crisis. Click here for details about SASSEN What is SASSEN →
