Stay hydrated all summer long, without the plastic.
Until now, staying safe and avoiding heatstroke has meant buying lots of plastic bottles to stay hydrated and cool.
This summer, we’re changing that. We’re creating a ‘new normal’ for hydration.

Through a combination of initiatives with city governments and global brands, we’re ushering in a new era of #PlasticFree hydration. Uncover our network of tens of thousands of refill spots with your reusable bottle.
With mymizu, you’re always One Tap Away From Water.

Nike x mymizu

We are very excited to be teaming up with Nike this summer to create a new era of sustainable sports! Join our challenge to run 2.5 million kilometers - the length of all PET bottles used in 6 months in Japan - via Nike Run Club until 20th August.

As you are running or walking, Nike and mymizu will increase refill spots across Tokyo to help athletes hydrate and refuel on the go - without the plastic.

More details & sign up for the challenge is here (Japanese only).


Kobe City x mymizu: Campaign



This summer, we’re partnering with Kobe City on the "Let's Drink Water Campaign", an initiative to encourage people to stay hydrated and avoid heatstroke in the summer heat - something that’s especially important when we’re wearing masks.

Shops and businesses across the city will join the mymizu network, providing people with free, convenient hydration, wherever they are!
