Dream Background

When we see news about the "100-year life era," it makes us reconsider the need to extend our healthy lifespan, but honestly, most of us want to avoid strenuous exercise.

Also, we hear voices from people who want to do something for environmental protection but don't know what to do.

To address these desires simply and without overthinking, we developed "SESUJI," a balance exercise tool that uses recycled plastic as its core material.

Current Initiatives

"SESUJI" has a regular tetrahedral shape, which allows for forced balance exercises utilizing its instability, enabling core training for all ages.

Use with the apex of the triangular pyramid shape facing downwards.

The recycled plastic used for the core material is polyethylene, a resin widely used in various containers, miscellaneous goods, packaging materials, and automotive parts. It is made by collecting scraps and surplus materials discarded during manufacturing, as well as polyethylene that has completed its first mission, then finely crushing and regenerating them.

The core material uses 100% recycled polyethylene.

Furthermore, the core material is hollow and floats in water, so it can also be used as a flotation device in times of disaster.

K-Tool's Dream

"SESUJI" has completed design registration as an exercise tool with a regular tetrahedral shape in major countries, and we plan to disseminate it worldwide as a unique Japanese product.

By changing the cover design, it can be customized not only with the long-tailed tit (Shimaenaga) but also with appearances preferred by users.

Starting with this product, our company aims to develop tools that slightly assist people's lives worldwide, making them more enjoyable and convenient, and to see as many smiles as possible.
