Tea-Growing Region in Japan | Kagoshima Prefecture

When the first-flush tea season begins in Japan each spring, it starts in Kagoshima. The warm southern climate of Kyushu allows Kagoshima farmers to harvest their earliest tea in late March — weeks before the famous tea regions further north. This early-harvest advantage is part of what has driven Kagoshima's rise to become Japan's largest tea-producing prefecture by volume.

Kagoshima tea covers Sencha, tamaryokucha (a distinctive curled-leaf green tea), and several other styles grown across the southernmost point of Japan's main islands. For an overview of all the tea-growing regions in Japan, see our hub article.

Kagoshima: Japan's Largest Tea Prefecture by Volume

Kagoshima has grown to become Japan's largest tea-producing prefecture by volume. According to crop statistics from Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF), it produced about 30,000 tonnes of aracha (crude, unrefined tea) in 2025, about 40% of Japan's estimated 75,100 tonnes, having overtaken Shizuoka in 2024 (27,000 tonnes against 25,800) — a remarkable climb for a region that only developed serious commercial cultivation after World War II. The late start was actually an advantage: Kagoshima could adopt mechanization and large-scale farm management from the beginning, without the legacy infrastructure of older regions. Minamikyushu City is now the top municipality in Japan for tea production, exceeding any single city in Shizuoka.

Kagoshima tea is often described as milder and less astringent than Shizuoka Sencha — a character that makes it particularly well-suited for cold brewing. The softer flavor profile comes from the warm, consistent climate, which produces leaves that develop more rapidly but with lower astringency than teas grown in cooler highland conditions. Compare this with the rich, rounded character of Shizuoka Sencha, where volcanic soils and cooler seasons concentrate different flavor compounds.

What Kagoshima Tea Tastes Like

The dominant style is Sencha — bright, clean, and accessible. Many Kagoshima producers use fukamushi (deep-steam) processing to manage the bitterness that the long sunshine hours can produce, and some also use shading before harvest to soften the leaf character, resulting in a very dark green liquor with concentrated umami and minimal astringency. Cold-brewed Kagoshima Sencha is particularly smooth.

The main cultivars include Yabukita (the national standard), Yutakamidori (Kagoshima is Japan's largest producer of this cultivar), Saemidori, Asatsuyu, and Okumidori. Each cultivar produces a slightly different flavor profile even within the same region and season.

Climate: Southern Japan's Volcanic Terrain

Kagoshima sits at the southern tip of Kyushu, directly facing Sakurajima — one of Japan's most active volcanoes. The volcanic soil is mineral-rich and well-draining, supporting vigorous root development in tea plants. The warm, humid climate from the East China Sea brings consistent rainfall and avoids the frosts that limit cultivation further north.

The long growing season — tea can be harvested from first flush in late March through autumn Bancha in October — means Kagoshima produces more harvests per year than most other prefectures. This volume, combined with mechanized cultivation on relatively flat land, makes Kagoshima tea accessible and competitively priced.
