01 About mymizu


mymizu ('mizu' means 'water' in Japanese) is an award-winning movement to tackle plastic waste and promote sustainable living.

The free mymizu app is a crowd-sourced platform connecting people to 12,000+ free water refill stations (water fountains and partner stores) across Japan and 200,000 globally.

At these locations, you can refill your water bottle for free, instead of buying plastic water bottles - it’s good for the planet, your body and your wallet!

Since 2019, mymizu’s plastic-free hydration network and movement have been co-created with 200,000+ people through crowdsourcing and the voluntary participation of 2,400+ partner stores (“Refill Partners”) across Japan and the world, saving millions of PET bottles from going to waste.

The mymizu community - app users and contributors, stores, partner schools and universities, companies, and so on - is the driving force behind the platform’s growth and impact.

mymizu is operated by nonprofit organisation Social Innovation Japan.
