Nagomiyutaka (なごみゆたか) can be translated as “relaxing richness”.

It was named this way because it is rich in L-theanine, which is a relaxing compound.

History of Nagomiyutaka

In 1988 at the tea branch of the Miyazaki Research Institute, a cultivar called Saitama #16 (埼玉16号) was crossed with a native cultivar from Fukuoka called Fuku 8 (福8).

Saitama #16 is a cross of Yamatomidori, and Sai 23F1-17, which in turn comes from Yabukita and Sayamamidori.

The idea was to find a superior cultivar for producing kamairicha.

The best seedling from the batch was tested on various occasions, until it was named Nagomiyutaka and it became registered in 2012.
