About Biwa Cha

cup of Biwa cha (Japanese Loquat leaves tea)

Biwa Cha is made from dried leaves of Japanese Loquat tree, a large evergreen shrub native to subtropical southern Japan. It is a mild and pleasant beverage, with numerous health benefits. It is quick and easy to prepare at home, as Japanese have done for centuries. You can serve it hot or cold.

The glossy leaves are picked green, after which they are thoroughly washed and cleaned. After a period of drying, the leaves are chopped into small pieces and become ready for brewing.


For higher quality, Japanese cut the dried leaves in ribbon-shape strips, in a style called Tanzaku-kiri (短冊きり). The larger cut Tanzaku-kiri leaves remain closer to their original, natural form, at the same time minimizing oxygen exposure along the cut edges.

How to Prepare

Japanese Senjiru Method

Senjiru (煎じる) brewing in essence is a rapid boil, followed by simmer and then cool down period. It is a time-tested Japanese method for extracting the maximum goodness locked deep in the leaves, and to deliver the optimum combination of aroma, flavor and color.

About Water Quality

Biwa Cha is a mild and subtle tea. If your tap water tastes bad, then so probably will your tea.

You should use fresh, good quality water without a lot of minerals (but not distilled water) to get the best flavor out of your tea. If using tap water, let it run cold for at least 10 seconds before using it.

Using a Non-reactive Kettle

Herbal teas, and indeed all teas, should be prepared in kettles made from a material that is as non-reactive as possible. The material your kettle is made of can chemically react with water, and cause contamination.  

Aluminum kettles should definitely to be avoided. Aluminum is a reactive material which has been proven to cause toxic contamination. Glass, ceramic, stainless steel, enamel, marble or cast iron are excellent non-reactive, non-toxic materials.
