Understanding the Okumidori Cultivar
Okumidori is a Japanese tea cultivar developed in 1974 through a cross between the Yabukita cultivar and Shizuoka Zairai No.16. The name translates to “deep green,” reflecting its vibrant color when processed into matcha.
This cultivar was specifically bred to extend the harvesting period and improve flavor characteristics. Okumidori is a late-budding variety, maturing approximately 8 to 11 days later than the widely grown Yabukita cultivar.
Cultivation occurs primarily in renowned tea regions like Uji and Shizuoka. Its development addressed practical agricultural needs while enhancing the diversity of flavor profiles available to matcha producers.
Flavor Profile and Sensory Characteristics
Taste and Aroma
What makes Okumidori distinctive among matcha cultivars? The answer lies in its harmonious balance of taste elements that appeal to both traditional and modern palates.
The flavor delivers strong umami with mellow sweetness and remarkably low astringency. This creates a well-rounded taste experience without the harsh bitterness that can characterize some tea cultivars.
Visual and Textural Qualities
Okumidori matcha exhibits a bright, intense green color that signals its high chlorophyll content. The powder has a fine texture that whisks smoothly into a frothy consistency.
The aroma is notably strong and pleasant, contributing to the overall sensory appeal. This combination of visual vibrancy and aromatic intensity makes Okumidori immediately recognizable to experienced matcha enthusiasts.
How Okumidori Compares to Other Matcha Cultivars
| Cultivar | Harvest Timing | Flavor Profile | Key Characteristics |
|---|---|---|---|
| Yabukita | Early | Balanced umami and astringency | Most widely grown, reliable standard |
| Okumidori | Late (8-11 days after Yabukita) | Strong umami, low astringency | Frost-resistant, harmonious taste |
| Samidori | Mid-season | Mild sweetness, minimal bitterness | Deep green color, gentle profile |
| Asahi | Early | Creamy richness, outstanding fragrance | Rare, premium pricing |
The comparison reveals that Okumidori occupies a unique position. It offers intensity without harshness, making it versatile for various applications while maintaining distinctive character.
Cultivation Requirements and Growing Characteristics
Agricultural Advantages
Okumidori demonstrates several practical benefits for tea farmers. The cultivar produces high yields and features a strong, upright tree shape that simplifies maintenance and harvesting.
Its cold resistance makes it particularly suitable for mountainous and frost-prone areas. This expands the geographic range where quality matcha can be produced reliably.
Cultivation Considerations
- Soil requirements: Okumidori prefers acidic soil with pH levels between 5.5 and 6.5 for optimal growth and flavor development.
- Shading protocol: Plants undergo shade cultivation before harvest to enhance chlorophyll and amino acid content, critical for premium matcha quality.
- Disease management: The cultivar shows vulnerability to anthracnose disease and requires careful monitoring in susceptible regions.
- Harvest timing: Collection occurs 6 to 8 days after Yabukita, allowing producers to stagger harvests and extend processing periods.

What does Okumidori mean in Japanese?
Okumidori translates to late-budding green in Japanese. The name breaks down into two parts: oku meaning inner or late, which refers to the cultivar’s characteristic of budding about one week later than standard varieties, and midori meaning green, describing the vibrant jade-green color of its leaves and the matcha powder produced from them.
How does Okumidori's flavor profile differ from other matcha cultivars?
Okumidori offers a mellow, savory taste with low astringency that sets it apart from other cultivars. You’ll notice:
- Delicate sweetness with subtle notes of green pea and mango
- A hint of coconut aroma that adds complexity
- Rich umami character without the sharpness found in Yabukita
- Well-rounded flavor that blends smoothly with other cultivars
This balanced profile makes it popular for ceremonial grade matcha.
Why was Okumidori developed in Shizuoka?
Growers in Shizuoka created Okumidori in 1974 by crossing Yabukita with a native Shizuoka cultivar called Shizuoka Zairai #16. The goal was extending the harvesting season and improving frost resistance. Since Okumidori buds later than standard varieties, it avoids damage from early spring frosts that can devastate tea crops. This late-budding trait also spreads out the harvest window, allowing producers to manage labor more efficiently across different cultivars.
Where in Japan is Okumidori grown for matcha production?
While Shizuoka Prefecture remains the primary growing region where Okumidori originated, this cultivar has expanded to the Uji and Wazuka regions near Kyoto, which are famous for premium matcha production. Specific fields include Erioshi, Aoi Mori, Monzen, and even the uniquely named Prison Tea Field. Its frost-resistant nature makes it adaptable to various climates throughout Japan’s tea-growing regions.
Can Okumidori be used for teas other than matcha?
Yes, Okumidori wasn’t originally bred specifically for matcha. Producers first cultivated it for sencha production, taking advantage of its mellow flavor and vibrant color. Today, tea makers use Okumidori for three main applications:
- Sencha – its original purpose, producing smooth leaf tea
- Gyokuro – shade-grown premium tea with intense umami
- Matcha – increasingly popular due to its jade-green color and balanced taste
This versatility makes it valuable for producers who want flexibility in their product lines.
What makes Okumidori matcha appear so vibrantly green?
The striking jade-green color comes from high chlorophyll content in Okumidori leaves. This cultivar produces a pure green liquor with minimal yellow tint, unlike some varieties that develop yellowish hues. When shade-grown for matcha production, the plants boost chlorophyll levels even further as they compensate for reduced sunlight. The combination of Okumidori’s natural pigment production and proper shading techniques results in that eye-catching emerald color that signals quality matcha.
