Frequently Asked Questions

All of our teas and teaware are made in Japan.

All of our organic teas are certified by the Ministry of Agriculture, Forestry, and Fisheries of Japan. Organic cultivation is to grow agricultural crops in the historic way before modern agriculture, without any chemical fertilizer or pesticides, using only natural organic fertilizer. Organic tea has a simple and traditional flavor.

In Japan, conventionally-grown teas are strictly controlled in the use of pesticides by the Concentration Standard of Residual Agricultural Chemicals in Japan. The Concentration Standard of Residual Agricultural Chemicals, established in 2006 in Japan, allows only 0.01ppm of residual concentration. The criterion measure level is more stringent than anywhere else in the world. You can be assured that our conventionally-grown teas are met with the highest standards.

We guarantee fresh quality for one year since breaking the seal. You can still drink it after the best by date but the flavor and scent may fade over time.

Keep in a dry, dark, and cool location for best results. Seal the tea pouch firmly and avoid moisture, excessive heat, light, and air. We highly recommend storing your tea in an airtight chazutsu tea canister.

All of our tea bags are carefully packed with organic loose leaf tea in pyramid-shaped corn fiber mesh tea bags for quick and easy brewing. PLA Corn Fiber is a new environmentally friendly material that does not include micro plastics. See article for more detail.

Iced tea can be brewed two ways. If you want to brew tea instantly, brew it like any normal cup of hot tea and add ice. Another way is to cold brew the tea. Fill a pitcher with water and throw in the tea bag and chill in the fridge overnight. We recommend starting with one tea bag for every 8oz of water (1 cup). Of course, adjust the ratio of tea and water to your taste preferences.

This all depends on the water temperature and brewing time but on average, our green teas have 35mg per 8oz cup (about a third of coffee). On the other hand, our roasted green tea (hojicha) has 15mg, whereas herbal teas, such as barley tea (mugicha) is caffeine free.

All of our green teas are gluten-free. Most of our herbal teas are also gluten-free, except for Mugicha Barley Tea.
