Join mymizu’s Arakawa River Cleanup!

🌊 Join mymizu’s Arakawa River Cleanup! 🌊

🎉🌍 Celebrate 6 Years of mymizu, launching a new campaign, and participate in World Cleanup Day!

On Sept 20th, we’re joining millions of people worldwide for World Cleanup Day and rolling up our sleeves for a community river cleanup at Arakawa 🌍✨ This day is extra meaningful for us, because we have a couple of reasons to celebrate together:

🎉 mymizu turns 6 years old!

🚰 We’ll be launching a brand-new, participatory campaign (details coming soon 👀)

Over the past six years, mymizu has grown into a global community, inspiring hundreds of thousands of people to refill their bottles instead of buying single-use plastic ones. Now, as we enter our 6th year, we’re taking the next step together - and this cleanup is the perfect way to kick it off.
