Why Bonsai Culture Took Root in Kagawa

The Kinashi and Kokubunji areas of Takamatsu, Kagawa Prefecture, are the largest pine bonsai producing area in Japan, accounting for roughly 80% of the country's pine bonsai (according to materials from Kagawa Prefecture and the Ministry of Agriculture). It is also unusual in being able to handle everything from raising seedlings to finishing a tree within one area. This article explores the historical background behind how bonsai culture took root in Kagawa, and what makes it so special.

A Climate Shaped by the Seto Inland Sea

Kagawa Prefecture, facing the Seto Inland Sea, enjoys a mild climate with relatively little rainfall. With minimal risk of severe frost or heavy snow, and a fairly stable climate year-round, the region has long been recognized as ideally suited to growing pine and other bonsai trees. Well-draining soil combined with a gentle climate provides the foundation for the beautifully shaped trees that emerge from years of careful cultivation.

The History of Kinashi and Kokubunji

According to Kagawa Prefecture, bonsai growing in Takamatsu began about 200 years ago, in the Bunka era (1804–1818), when black pines growing wild on islands in the Seto Inland Sea were lifted into pots. Since the Meiji era, the town of Kokubunji has also been known as the birthplace of the nishiki pine, a black pine variety whose bark swells into wing-like ridges. Generation after generation, local growers have passed down their techniques, building the region into the major production area it is today, from young pine stock to finished bonsai.

Why Kagawa Is Known as the "Home of Bonsai"

Kagawa's pine bonsai make up roughly 80% of the national total. What sets Kagawa's bonsai culture apart isn't just a handful of individual growers, but an entire regional system of cultivation, shaping, and distribution. With so many growers raising pines in the same area, skills have been handed down and the region has built real depth as a producing area.

The Value of One-of-a-Kind Craftsmanship

Shaping a bonsai's form over decades, starting from a single seed or sapling, is an accumulation of time and skill. Through years of careful pruning, pinching, and repotting, each tree develops its own character and form. Even among trees of the same species, no two bonsai ever share the exact same shape. As a black pine ages, its bark grows thick and deeply cracked, as in the photo below.

For example, our Japanese Black Pine (Thick Trunk, Grand Form) shows the time spent caring for it in its thick trunk and broad, spreading form.

Frequently Asked Questions

Can a bonsai grown in mild Kagawa be kept in a colder region?

Pines such as black pine are fairly cold-hardy and can be enjoyed in many regions when kept outdoors in a sunny, well-ventilated spot. In areas with hard frosts or persistent cold winds, a general guideline is to move the tree under the eaves or to another sheltered spot in winter. See Winter Care and Cold Protection for details.

Can I buy another bonsai with the same shape?

Every bonsai at Kagawa Bonsai is one of a kind, so no two trees are the same. You can look for trees of the same species or a similar style in our product list. If you have any questions, please ask us through our contact form.
