Where It’s Grown

KOTOSHINA Kyoto Uji Green Tea

At KOTOSHINA, we enrich our products with premium tea leaves cultivated in the certified organic tea gardens of Uji, Kyoto. Blessed with an ideal climate and nutrient-rich soil, Uji is a historic region renowned for producing exceptional green tea, deeply rooted in the tea culture of Japan's ancient capital. Nurtured with meticulous care, KOTOSHINA’s green tea delivers a remarkably fresh aroma and a clean, beautifully balanced flavor. 

Our Philosophy

The Benefits of Green Tea

Beyond its delicious taste, green tea brings rich beauty benefits to the skin. While many associate green tea with "catechins," these powerful antioxidants offer a protective strength two to three times greater than vitamins C and E. By effectively neutralizing free radicals that can lead to signs of aging, they are highly recommended for caring for skin concerned with wrinkles and loss of firmness.

Additionally, green tea is naturally rich in vitamin C, which helps refine skin texture and gently works to fade the appearance of dark spots and hyperpigmentation. Infused with these skin-loving nutrients, KOTOSHINA skincare harnesses the pure essence of green tea. Welcoming tea into your daily routine helps maintain, nurture, and promote a healthy, radiant complexion.

Organic

JAS Certified Organic

From cultivation in the fields to the final processing, KOTOSHINA's tea is produced under a consistent system free from chemical fertilizers and harmful synthetic substances, fully meeting the strict Organic JAS certification standards.

To qualify for Organic JAS certification, the soil must be cultivated without chemical pesticides or fertilizers for a minimum of three years. The Organic JAS logo—inspired by the sun, clouds, and plants—is a protected seal of assurance. Only products that meet the rigid organic standards set by Japan’s Ministry of Agriculture, Forestry and Fisheries, and bear this mark, are legally permitted to be labeled as "organic."
