A promise not to pollute the sea. A magic detergent that needs zero rinses.|Ganko Hompo

Being kind to the environment doesn't have to mean enduring more.
Cut down on rinsing — save time and water.
Ganko Hompo's tools build kindness to the planet and free time for you, at the same time.

You can let yourself off the hook a bit more

Founded in 1992. Based in Chigasaki City, Kanagawa, "Ganko Hompo" began with research on tanker oil-spill cleanup. From the wish "not to pollute the sea any longer," the laundry detergent "Umi e..." (To the Sea...) was born — an earth-friendly detergent that removes dirt with a small amount and is quickly broken down by microorganisms. Even more revolutionary: laundry is finished with "zero rinses." Protecting the environment also makes housework easier. They keep proposing this kind of new daily life.

Ganko Hompo

Why "Ganko Hompo" Is Chosen | 3 Reasons

0 1

The "zero rinse" that overturns common sense

Thanks to an anti-redeposition agent, dirt that has come off once does not return to the clothes. So even using leftover bath water, you can spin-dry without rinsing. Not only does this save water and electricity — it also greatly reduces the damage (friction) to your clothes.

0 2

Overwhelming biodegradation speed

Under the international DOC test method, more than 70% degradation in 21 days qualifies as "readily biodegradable." "Umi e... Step" records an astonishing 94% degradation in just 24 hours and 100% in 7 days.

0 3

The "power of rubber" — no detergent needed

Although they're a detergent maker, they also advocate "cleaning that uses as little detergent as possible." "Ganko Cross," processed with rubber latex, lifts off oil stains and water scale like an eraser — just wet it and rub.

Editor's Note

📝 User Perspective

Since I started using "Umi e... Step," my whole idea of laundry has changed. With no rinsing required, laundry time has been cut in half and the water bill has dropped visibly. Above all, the fact that wool, silk and down jackets can be washed with this one bottle is just too easy! It finishes fluffy without fabric softener, and the faint lavender scent is comforting. I'm also happy that the laundry area is tidy because I don't need lots of different detergent bottles.

Earth- and Wallet-Friendly Masterpieces | 5 Editor's Picks

From the "Umi e..." series with many repeat buyers, to magic cloths that clean without detergent. Items you can't go back from once you've used them.

Revolutionary

Laundry Detergent "Umi e... Step"

Zero rinses, no fabric softener. Laundry, finished with this one bottle.

A highly biodegradable laundry detergent born from research into tanker oil-spill cleanup. It dissolves easily in water and produces little foam, so rinsing isn't needed. A neutral detergent that can wash wool, silk and down, letting you care for dry-mark clothing at home. Lavender essential-oil scent.

💡 Recommended Usage

For daily laundry, delicate-wear washing and down jacket washing. Diluted and sprayed, it also works for wiping rooms.

Magic Cloth

Maki-Maki Ganko Cross

No detergent needed. Lifts stains off like an eraser, with the power of rubber.

A cleaning cloth made of cotton fabric soaked in rubber latex (natural rubber). Just wet it and rub — oil stains on the stovetop, water scale around the sink, tea stains and more come off remarkably well. A roll type you can cut to the length you need with scissors.

💡 Recommended Usage

For oil stains around the kitchen, tub scale, and to remove black scuffs from sneaker rubber. Also for inside the microwave, where you don't want to use detergent.

Multi-Use

Mori to... (Dish Detergent)

From dishwashing to face washing. A versatile detergent with a forest scent.

A dish detergent — the sister product of "Umi e...". Excellent at finely breaking down oil stains, and it keeps oil from coating the drainage pipes. So gentle on skin that it can even be diluted and foamed for use as "face wash" or "body soap." A scent like an Aomori hiba forest.

💡 Recommended Usage

For dishwashing, wipe-style face washing and window glass. Ideal where drainage facilities are not available — at campsites and the like.

Stain Remover

Shacchitto Spray

For stains you'd given up on. A bleach-free stain remover that doesn't damage fabric.

A spray that targets food drops on clothes and sebum on collars and cuffs. The cleaning power of "Umi e..." in a concentrated form, with no bleach or fluorescent brighteners — so it's safe on colored prints. Just spray it before washing, as pre-care.

💡 Recommended Usage

For shirt collar stains, food drops and blood stains. Also excellent as a detergent when washing sneakers.

Returns to Earth

Korekara no Fukin (Sponge Wipe)

Outstanding absorbency. A sponge wipe you can bury in soil at the end to return to nature.

A 100% natural-material wipe made from fiber (cellulose) from wood off-cuts and cotton. It absorbs more than 10 times its own weight in water and dries quickly, so it stays hygienic. Once it's worn out, bury it in soil — microorganisms break it down and return it to the earth.

💡 Recommended Usage

As a dish-drying mat, a wipe for the table, or for water droplets in the washroom. Also handy for wiping down after a car wash.

Summary: Beyond the drainpipe is the ocean.

The household wastewater we send down the drain every day eventually reaches the ocean.
