Hand-harvested in Inawashiro. Rooted in Samurai culture. Supported by modern wellness research.
Ninja Tea is a rare Japanese herbal tea made from the wild seeds of Hishi, a traditional water plant growing naturally in Lake Inawashiro, located in Aizu — also known as Samurai City.
It is a caffeine-free, earthy, and soothing tea with a deep cultural background and a growing international following.
Why Is It Called “Ninja Tea”?
The raw ingredient, Hishi seeds, carries unique historical meanings in Japan:
✔ Origin of the Ninja “Maki-bishi”
Hishi seeds are known as the original form of maki-bishi（撒菱）, the spiked objects ninja scattered to slow down pursuers.
✔ A traditional Japanese symbol of good fortune
The Hishi leaf appears in old family crests (家紋), symbolizing
- protection
- prosperity
- the growth of family lines
✔ Aizu’s Samurai culture
Inawashiro is part of Aizu, a region famous for samurai history and warrior traditions.
Ninja, unlike samurai, lived in secrecy — but descendants still exist across Japan today.
Ninja Tea brings these cultural layers into a single cup.
A Japanese Wellness Tea Gaining Attention
In Japan, Hishi has recently become popular as a natural wellness tea.
The outer skin of the seed contains Hishi polyphenols, which have been the subject of growing research.
Studies in Japan have explored the potential of these polyphenols to:
- support a slower rise in blood sugar
- help reduce active oxygen
- support skin concerns such as dark spots, uneven tone, and the appearance of fine lines
These are not medical claims, but interest in Hishi Tea has surged rapidly — resulting in domestic shortages of Japan-grown Hishi.
Ninja Tea uses only 100% domestic Hishi seeds harvested from Lake Inawashiro.
Hand-Harvested at Lake Inawashiro
Ninja Tea is produced from Hishi plants growing naturally in one of Japan’s clearest lakes.
Local programs allow visitors to:
- harvest Hishi seeds by hand
- taste freshly roasted seeds
- collect real maki-bishi washed up on the lakeshore
Our tea is made from the same wild plants used in these cultural experiences.
