Caffeine in Japanese Green Tea


Japanese green teas are popular for their rich flavors and aromatic brews, providing a unique experience in each cup. Each type of tea ranges in caffeine content, depending on how the tea leaves are processed after being harvested. In comparison to other green teas, Japanese green teas often have higher caffeine content due to the gentle steaming process.

However, the effects of caffeine from green tea are different from those in coffee as caffeine from tea is metabolized differently by the body. While caffeine in coffee gives you a quick, short jolt of energy, the caffeine in tea is bound to antioxidants which slows absorption by the body. In return, you receive a steady and even supply of caffeine for a longer period of time. This allows the body and mind to enjoy long lasting, health alertness without the jitteriness often experienced from coffee.

There are also Japanese green teas and herbal teas known to have low or no caffeine. Read below for our recommendations on the best tea for you, based on your personal caffeine needs and preferences.

High Caffeine Green Tea

For those who may need an early morning energy boost, both Gyokuro and Matcha green tea are the best options. Since both teas are grown in the shade, they naturally contain a higher caffeine content. Gyokuro shade-grown green tea is best enjoyed steeped in tempered warm water, while Matcha powdered green tea is best enjoyed whisked.

Due to its versatility and abundant health benefits, matcha green tea has become one of the most popular Japanese green teas available. Additionally, matcha green tea can easily be incorporated into mixed drinks such as matcha lattes, matcha cocktails, and matcha popsicles. Thanks to this, matcha has become a daily staple in many morning routines, especially for those in need of a caffeine boost to start the day and prefer a healthier alternative to coffee.

Medium Caffeine Green Tea

Sencha green tea is a classic choice if you’re looking for a pick-me-up during the day or after a meal. It offers a moderate caffeine boost but much lower than caffeine from coffee or the shaded green tea options like Gyokuro and Matcha. Variations of Sencha include Fukamushicha, which is a deeply steamed green tea. Generally, this process produces a non-astringent, full-bodied and vibrant brew since the tea leaves soften from the longer steaming. Regardless of which type you choose to drink, sencha green tea is an ideal option for a moderate caffeine boost.

Low Caffeine Green Tea

If you prefer lower caffeine content in your tea, or you want to have a cup with your dinner or before bed, Hōjicha is the perfect choice. Hōjicha tea leaves are roasted after the steaming process, while other green teas are only steamed. The high temperature burns away most of the caffeine within the leaves. The toasty aroma and flavor is quite popular especially with new tea drinkers. Hojicha has risen in popularity around the world due to this unique flavor profile.

No Caffeine

For those who prefer to avoid caffeine altogether, there are also Japanese teas which are completely caffeine-free. Herbal teas are great for those sensitive to caffeine. Herbal teas are good to drink at any time of day. Mugicha (Barley Tea), Sobacha (Buckwheat Tea), and Kuromamecha (Black Soybean Tea) are Japanese herbal teas that can be enjoyed hot or cold—each with its own set of unique health benefits and no caffeine content.
