Makuake Project Page

As we reach this milestone of our 92th anniversary, we began questioning whether it was time to reevaluate the meaning of 'manufacturing.'
This reflection led us to a strong conviction: 'As a partner supporting daily life, we want to help our customers become the protagonists of their own lives and shine in their own unique way.'
Born from this vision, our new products embody what we call our 'second founding'—a renewed commitment. We aim to deliver the surprise and comfort of one-touch opening, along with the excitement of choosing your own style through the bottle’s material and color, directly into your everyday life.
