Gardens that drink rain, not the mains

Where it started

A dry summer and a dead lemon tree

The company began with one failed lemon tree on a Jingumae balcony. Its owner — now our founder — kept missing the watering can during a long, hot Tokyo rainy-season gap, and the tree gave up. The lesson was simple: a garden should not depend on a person remembering. It should depend on a schedule, a sensor and a tank of rain already collected from the roof above it.

We spent the following seasons learning drip emitters, soil moisture, downpipe diverters and the particular habits of citrus, fig and plum in a humid city. What we learned turned into the service we run today.

What we believe

Less water, more garden

Drip irrigation delivers water to the root, slowly, with almost nothing lost to evaporation or runoff. Paired with a rainwater tank, a typical garden on our system draws a fraction of the treated water a sprinkler or hose would use across a year. That is not a slogan — it is the point. A healthy garden and a light water bill are the same project, approached from two sides.

• Rain caught from the roof instead of poured from the tap
• Water metered to each plant, timed to the weather
• Fruit trees pruned and fed for fruit, not just leaves

How we work

Audit, build, hand over, return

Every garden starts with a free audit. We measure the roof catchment, test the soil, read the sunlight and ask what the garden is for. From there we design the tank, the zones and the emitters, install in a day or two, and set the controller to the season. Then we come back — because a watering system that is never checked drifts out of tune within a year.

The people

A small crew of growers and plumbers

We are gardeners who learned irrigation and fitters who learned horticulture. There is no call centre — the person who audits your garden is usually the person who returns to prune the fig in winter. We keep the team small on purpose, because a water system is a long relationship and names matter more than scale.

What we tend

Fruit, first and foremost

Citrus, fig, persimmon, plum and blueberry all do well in the Tokyo climate when their water and their pruning are right. We specialise in the awkward cases: a lemon in a planter too small, a persimmon that fruits every other year, a fig overgrown against a wall. Getting the water steady is usually half the cure.

Our workshop sits in Jingumae, Shibuya, a short walk from the station. Bring photos of your garden or let us visit it — either way the first conversation is free, and it usually starts with the roof above your head and the rain it already catches.
