El riego de cobre de cuello largo puede

This is a professional-grade watering can used by bonsai artists. It is designed specifically for bonsai, with a handle that maintains balance even when at maximum capacity, allowing for large and precise watering. The copper watering can enhances plant growth through the antibacterial properties of copper, making water less prone to spoilage and benefiting plants with the effects of dissolved copper ions. A mesh filter is attached to the spout to prevent leaves and debris from entering when drawing room-temperature water from containers like rainwater jars. Extending the length of the watering can's spout allows for controlled water pressure, ensuring steady and uniform watering.

NEGISHI

"We invigorate all plants with our watering cans, inheriting and preserving traditional craftsmanship."

Copper watering cans feature the antibacterial properties of copper, which make the water less susceptible to spoilage. The effect of copper ions dissolved in the water also promotes the growth of moss on bonsai. To prevent leaves and debris from entering while drawing room-temperature water from containers like rainwater jars, a mesh filter is attached to the spout. By extending the length of the watering can's spout, we provide a watering can that allows for controlled water pressure, ensuring a steady and uniform watering experience.

ARTISAN STORY

Yoichi Negishi / Negishi Industry
Negishi Industry was founded in 1944 by a first-generation roofing craftsman who specialized in shrine and temple roofs. He established the company to produce horticultural metal goods using tinplate. In 1966, the second generation introduced the idea of applying techniques from Sendai to create copper, brass, and stainless steel watering cans, specifically designed for bonsai. He also proposed these to bonsai associations. Since then, Negishi Industry has specialized exclusively in the production of watering cans, dedicating itself to perfecting this craft.

ACHIEVEMENTS

・The copper watering can was selected as a trend at Ambiente 2016.
・The copper watering can was chosen for the 2016 Golden Tin Design Award.

JORO / JAPANESE WATERING CAN

About 150 years ago / 1870s / Meiji Period (1868–1912)

Japanese metal watering cans became increasingly specialized with modern horticulture and bonsai culture. Copper, brass or stainless steel sheets are formed into bodies with long spouts and finely perforated roses, designed to deliver water like gentle rainfall rather than a heavy stream.

For ordinary households a watering can may seem simple, but bonsai growers treat it as a precision tool. A long spout stabilizes pressure, while fine droplets protect moss and soil. High-quality handmade cans therefore remain valued by serious gardeners.

The tiny holes in the rose determine droplet size, spread and pressure. Their number, angle and diameter turn what looks like a simple container into something close to a fluid-control instrument. Copper versions add antibacterial properties and develop a distinctive patina through use.

Individual Differences

As each piece is individually handcrafted, slight variations in color, pattern, shape, and texture may occur. These subtle differences are a natural characteristic of handcrafted works, making each piece truly unique. We hope you will enjoy these individual variations as part of the beauty and character of Japanese craftsmanship.

Production Time

If an item is not currently in stock, it may be made to order by the artisan. As each piece is carefully handcrafted, production may take several months depending on the item and the artisan's schedule. We appreciate your patience and understanding.
