The Koka ninja school amassed knowledge of pharmacology, collecting herbs to maintain physical health, and treat wounds and illnesses.

The city, known as the birthplace of the prominent school, is focusing on ninja tourism. It organized the exhibition on the 10th anniversary of the opening of the learning center to demonstrate the links between ninja and the pharmaceutical industry.

such plants is still useful today.

The exhibition will run until the end of March, with closures on Mondays and certain other days as well as at the end of the year. Admission is free.
