Sakushima, Aichi
Eelgrass meadow アマモ場
For 22 years, the island’s schoolchildren have replanted this meadow by hand. It is the nursery where young fish shelter before they ever reach open water.
4.9 t CO₂ per hectare each year · eelgrass average
Golden Coastal IPL · Brewed on the Chiba coast
波々 Nami Nami is a crisp Japanese lager. Every can locks 1 kg of CO₂ into the seafloor for 100+ years and brings back 0.2 m² of living coast. Real, and traceable to the exact coastline.
What every can funds
Traceable & verified, every can back to its source
The beer
Bright gold and easy to love. Four hops (Citra, Mosaic, Chinook and Liberty) sit over a clean pilsner malt for citrus and tropical notes with a light lift of pine, then finish crisp and dry the way a proper lager should. Five percent, and built for a second round. Brewed by Kaigan Brewery in a renovated 1898 farmhouse in Minamiboso, Chiba, a few hundred metres from the water this beer helps restore.

How it works
STEP 01
Nothing to sign up for and nothing to add. The impact is funded the moment the beer is brewed, built into the price like the hops and the malt.
STEP 02
Each batch backs one named coastline and the community already bringing it back. Eelgrass at Sakushima, tidal flats at Onomichi, kelp at Erimo.
STEP 03
Scan the can. Follow it through PocketSeed to the exact credit retired and the coast it funded. Under a minute, all the way to the source.
Where the carbon goes
Tap a marker to explore
CO₂ is absorbed as the meadow grows. 0.2 m² of living coast per can above the seabed line, and 1 kg of CO₂ locked in the sediment for 100+ years below it.
You did not donate. You just had a beer. Japan’s coast is a little more alive because a lot of people did the same thing.
The coast
The impact is never abstract. It lands on a named stretch of Japan’s coast, chosen with the people already in the shallows bringing it back. Here are a few of them. The map grows with every batch.
One coastline per batch, in rotation.

Onomichi, Hiroshima
Tidal flat 干潟
The Seto Inland Sea’s own filter, and the birthplace of the clams and oysters a whole coast’s food is built on.
2.6 t CO₂ per hectare each year · tidal flat average
Erimo, Hokkaido
Kelp forest コンブ場
Kombu is the soul of dashi. Local fishermen are turning barren isoyake seabed back into forest, the strongest carbon habitat in the whole scheme.

Carbon is only where it starts. A restored coastline pays the people around it back in food, clean water, wildlife and pride. JBE certifies the carbon; the coast gives back the rest.
Seagrass nurseries and tidal flats raise the fish, clams and kombu behind Japan’s food culture. A restored coast is a working kitchen.
Meadows and flats filter the sea as it moves through them: clearer bays, healthier shellfish, better days on the water.
Fish shelter in the blades, birds return to the flats. Restored habitat means biodiversity you can actually see.
School replanting days, fishing co-ops, local stewardship. These projects run on community, and fund it back.
The art
The art is not decoration. Each edition, an artist answers one coastline in their own way, a real response to a real place. Their work rides wherever the can goes, into hands that do not always visit galleries, and stays on the record long after the batch is gone.
Community
This is not one brand doing good. It is thousands of people doing it together: every venue that pours it and every person who drinks it is part of the same coastline coming back.
What one round does
Every can locks 1 kg of CO₂ and brings back 0.2 m² of coast. Slide a night out.
A round with friends. About a bath towel of living seabed, funded.
Verified
Most good-for-the-planet claims ask for your trust. This one hands you the receipts. Every can opens a public record: the exact credit bought and retired for its batch, checked by an independent third party and certified by JBE, Japan’s blue carbon certification body. You can trace it all the way to the science, in under a minute.
100+ years
Only carbon that stays locked away for over a century even qualifies.
Independently checked
Every credit is verified by a third party, then registered and published.
