More information than the need to be overflowing in the modern day, the warmth of the old days is missing.
The "101" depicts a culture that is not forgotten as a rule.
It is also an anti-thease aimed at a large amount of information digital culture.
HYAKUICHI pays homage to the spirit of always beginning, without being too dull and delicate, the spirit of exploration and pursuing the future.

Regarded as a "10 ATM water resistance = strong waterproof" which can be used for water sports such as swimming, competitive swimming, yachting, and even skin diving.It is completely unaffected in the event of submersion or downpours, and has unnecessary toughness under harsh environments.
Please refrain from using it in situations where water pressure is above 20 ATM, such as when using a high pressure washer or jumping in high places.

What is SIS ?
The "SIS" logo is designed with a bis-motif that looks like the "SIS" has been converted into hieroglyphics.
The two screws arranged as fractions, are 1/1 = 1, representing the importance of not standing on people, and the beauty of their thoughts.
The screws have the power to connect, but their existence is discreet and understated.
If you were able to perform the important role of connecting people to people without anyone knowledge.
There is no better joy if you could connect it to those who agree.
Explore the joy of choosing your own personality in the multitude of intersecting information.
Be yours!
You in your world, not you in someone's world.
You are the world.
The world is you.
The "SIS" has been thinking of this.
