History of Asanoka Cultivar

Asanoka cultivar was grown by crossing two different tea varieties: Yabukita and a Chinese variety known as Hiramizu. There isn’t much information present on this Chinese variety, but after doing some research, we found that it comes from Pingshui Town in the province of Zhejiang, China. This town is quite famous for producing green tea in the form of gunpowder.

The two tea varieties were first intermingled at the Tea Research Institute in Chiran (Kagoshima) in 1994. After successful trials and testing, the cultivar got registered in 1996 under the Seed and Seedling Law with the number 5013.

Asanoka cultivar has been one of the most important parts of the Japanese green teas since 1996, and, as mentioned earlier, its production may even be increased due to its high yield, taste, aroma, and some other unparalleled benefits.

Characteristics of Asanoka Cultivar

Asanoka cultivar buds early and forms strong resistance to cold the minute after budding. The color of the leaves appears to be yellow-green, and the leaves are quite elliptical in shape with some luster. The young leaves are also soft and slightly thin.

When the Asanoka cultivar gets harvested, it shows a high yield. The cultivar not only contains a fruitful amount of amino acids but is also quite resistant to the novel gray blight. The aroma of this cultivar is quite different from that of Yabukita, but it is quite pleasant and appealing.

Of course, everybody wants a good start to the morning or the perfect end to a hectic day.

The blend of the sweetness with that of the grassy taste brings out more of a subtle flavor. Due to this balanced flavor and taste, the Asanoka cultivar is utilized as a base for a variety of tea blends.

Other than this, this cultivar also contains a tinge of caffeine that provides a boost of energy to the human body. So, if you want something sweet but strong, the Asanoka cultivar is the one you should start your day with.

Asanoka — Frequently Asked Questions

What is the Asanoka cultivar?

Asanoka (あさのか / 朝の香) is a Japanese tea cultivar whose name translates to "fragrance of the morning." It is mainly grown in Kagoshima Prefecture and currently accounts for about 1% of total Japanese tea production. Although that share is small, the cultivar's high yield, sweet flavor, and unusually rich aroma have given growers reason to expand its cultivation in recent years. Asanoka is often used as the base for premium tea blends, where its naturally sweet umami balances out sharper component cultivars.

Where does Asanoka come from?

Asanoka was created by crossing the dominant Japanese cultivar Yabukita with a Chinese variety called Hiramizu, which originates from Pingshui Town in Zhejiang Province. Pingshui is best known for producing green tea in the gunpowder style. The first crosses were made at the Tea Research Institute in Chiran, Kagoshima, in 1994. After successful trials, Asanoka was officially registered under the Seed and Seedling Law in 1996 as cultivar number 5013.

What does Asanoka taste like?

Asanoka has a naturally sweet, umami-forward flavor with notes of chestnut and sweet potato — flavors that emerge clearly in the first sip. The sweetness is balanced by a soft grassy undertone, which keeps the cup from feeling cloying. The aroma is unusually fragrant — distinct enough from Yabukita that experienced drinkers can identify it. The high amino-acid content is what produces both the sweetness and the rich aroma in the brewed cup.

How is Asanoka cultivated?

Asanoka is an early-budding cultivar that develops strong cold resistance shortly after budding — a useful trait given that spring frosts are a common risk in Japanese tea growing. The leaves are elliptical, yellow-green, slightly lustrous, and somewhat thin when young. The cultivar produces a high yield at harvest and shows strong resistance to novel gray blight, a fungal disease that can damage other Japanese cultivars. The two non-negotiable conditions for good Asanoka growth are abundant sunlight and good ventilation in the field.

Why might Asanoka become more popular?

Asanoka combines several traits that make it commercially attractive: a high yield at harvest, strong disease resistance, and a sweet, fragrant flavor profile that fits modern consumer preferences for less astringent green tea. The current 1% production share is a function of cultivation history rather than the cultivar's quality. As growers expand into warmer regions and look for alternatives to Yabukita, Asanoka is being trialed more widely. Many tea industry observers expect its production share to grow in the coming decade.
