About Our Tea: The Best Japan Can Offer

Like a fine wine, high-quality tea depends on more than pretty packaging. The age of the leaves, their growing conditions, and even soil fertility all impact the final flavor. For us, how tea is grown and processed is the secret to crafting a sweet, nutritious tea like no other.

We Strive for Sweeter Soil Cultivation with the Chagusaba Method

Chagusaba (茶草場) is an ancient farming method that uses human-made and natural grasslands to enhance soil fertility. This labor-intensive process takes thousands of hours every season, but tea farmers find it worthwhile for the crop quality it produces.

Practiced by Shizuoka farmers for centuries, grasses are grown throughout tea plantations in the summer months and later cut down to form an insulating layer to prevent the ground from freezing. Sugar cane and syrup are also added to the soil to enhance its sweetness.

By enriching, protecting, and revitalizing the soil beneath each tea tree, the chagusaba method sweetens the taste of each tea leaf by keeping plant roots warm and well-nourished throughout the winter. As the mulch breaks down in the spring, it adds much-needed silicic aid to the base of each tree, enriching the soil and preventing roots from getting burned from too much nitrogen.

‘Dusty’ Tea is A Sign of High Quality, Really!

At first look, our deep steamed tea leaves appear broken down, even dusty. This is because the longer processing time breaks down the tea leaves, especially at their tips. This leads to powdery tea that many compare to ceremonial matcha in taste, texture and nutrient levels.

Drinking tea leaves directly actually enhances the nutrition for your body. However, if you’re bothered by these fragments, a specially designed fukamushi teapot provides a finer mesh to filter them out.

Our Teas Contain Better Flavor with Deep Steaming Technology

After they are picked, steaming tea leaves is necessary to stop the oxidation process. Most green tea is steamed for just 30 seconds before being rolled and dried, which creates a brew that leaves you with a bitter taste.

In contrast, the sunny, yet foggy conditions throughout the Shizuoka region where it grows creates a firmer tea leaf, which needs longer steaming to release the complex flavors contained within. This means that our tea undergoes ‘deep steaming’ (aka fukamushi method 深蒸し) for almost two minutes - four times longer than regular tea!

Only thick, sun-soaked leaves benefit from deep steaming. The proprietary steaming machine used for every batch was developed specifically for our tea after years of research and study. Today, it is the leader in steaming technology in Japan, and the world.

Longer processing leads to a bolder flavor filled with the health-enhancing amino acid theanine. Every cup provides a robust taste, a smoother mouthfeel, a subtle hint of sweetness, and far less astringency.

About Our Tea Farm: Arahataen

Japanese Green Tea Co. is the only US-based company to source tea directly from Arahataen Green Tea Farms in the Shizuoka prefecture in Japan. Shizuoka has been the center of green tea cultivation in Japan for centuries, and the region’s intense sunlight and intermittent fog give each batch of tea its distinctive flavor.

Naturally fertile soil combined with a flat landscape free from sunlight-blocking mountains also contributes to the ideal growing conditions for robust tea plants.

On the farm, each leaf is harvested when it is thicker than usual resulting in higher amounts of catechins and chlorophyll from its longer sun exposure.

Humble Beginnings and a Bright Future

Arahataen Green Tea Farms was founded in 1948 by Mr. Arahata Eizo. Today, the 17-acre farm is managed by 55 employees who handle the cultivation, processing, and packaging of their award-winning tea right onsite.

Since 1969, Arahataen has been both the founder and leader of the Fukamushi Research Group (深むし研究会 天狗会), which developed better steaming technology for enhanced taste. The farm is also the first company to introduce clean room techniques for pu-erh tea, ensuring that unwanted bacteria stay far away from the fermenting tea leaves.

Arahataen Green Tea Farms received the Japanese National Tea Award, the most prestigious award for tea in all of Japan, in 1974, 1975, 1979 and 2010. The farm has also been awarded the National Quality of Tea Award, the Shizuoka Furusato Prize, and more, earning it the distinction of being one of the oldest and most respected tea companies in the region.

Today, the Japanese Green Tea Co. is proud to be the farm’s only distributor outside of Japan.

A Lasting Passion for Better Dirt

Arahataen Farms believes that the best tea begins with high-quality dirt. Through the Chagusaba method, the farm carefully cultivates crops of thick grasses around its tea trees like a compostable blanket to provide added nutrients directly to the soil every winter. The farmers also collaborate with researchers from Shizuoka University to study soil and the impact of its sweetness on the taste of the tea it cultivates.

This labor-intensive process protects the plant's delicate roots while giving each tree the nutrition it needs to grow, ensuring that only the best leaves make it into the company's tea.

A Note from Kei Nishida:

Though I’ve lived in the US for over 20 years, every time I visit Japan, I make it a priority to bring Japanese green tea back with me. Finding quality green tea outside Japan is difficult, and the mass-produced teas available in the states just don’t taste like ones I used to drink back home.

Little wonder. Just 7 percent of Japanese green tea is exported from Japan.

I’m not the only one who’s noticed what difference high-quality tea can make. Every time I went back to Japan, people asked me to bring them the same tea back, Arahataen’s Tea. Once they tried this tea, going back to other options was unbearable.

Truly, Arahataen tea takes different than any other I’ve tried. The farm uses sugarcane in their soil to make the tea taste sweeter while reducing its astringency (a deal breaker for many would-be tea drinkers).

Unfortunately for my newly-addicted friends, Arahataen didn’t export their tea outside of Japan. Suddenly, I knew there was a market ready to enjoy their tea, and I contacted Arahataen to see if I could distribute their tea outside of Japan. Thankfully, they said yes!

That is how our journey began.

Now, I’m happy to report that I can interact with tea lovers online and in person. Additionally, I feel fortunate and proud to bring one of the best Japanese teas into the greater world. The taste of Chagusaba method tea is loved by many tea specialists now, and our tea blend won the Global Tea Championship in 2017, 2018 & 2019. (Since 2020, the championship has been halted due to COVID.)

Our customers just keep coming back, and from the first sip, you’ll understand why. If you’re afraid to commit, we offer sample sizes for most of our products so that you can give them a try.

With Japanese Green Tea Co., I hope that you enjoy the best of what Japan can offer; green tea harvested with care and love.
