An annual ninja test from Shiga Prefecture will be held at a Tokyo temple for the first time this October, putting the town of Koka, home to a famous clan of the shadowy feudal warriors, in the tourism spotlight.

Zojoji Temple, the temple of the Tokugawa shogunate (1603-1868), will host the exam measuring knowledge of the Koka clan, which was closely tied to the founder of the shogunate, according to Koka's tourism association, which organizes the test. Due to a mispronunciation, the name of the clan is better known as Koga overseas.

The test has been held in Koka every year since 2008. Zojoji Temple was chosen as the site this year as Tokugawa Ieyasu, founder of the shogunate, is said to have escaped from Kyoto with ninja help in 1582.
