The arrival of an era in which we inhale for health


KENCOS represents the start of an era in which we inhale hydrogen gas as a new custom for maintaining our health. It enables us to inhale hydrogen gas directly through our mouths no matter where we are.

KENCOS was conceived for the purpose of ensuring that inhaling hydrogen for health becomes a familiar new custom. It is of a compact size that enables it to be carried around everywhere and it allows hydrogen to be inhaled through the mouth to enable use as a part of your everyday lifestyle. This high-quality hydrogen experience can be enjoyed at home or in the office, and it supports a daily sense of positivity.
