The Iga-Ryu school of ninjutsu (ninja arts) was one of the top two training centers for Japan's ancient spies and assassins in the 14th century. At the ninja residence, a guide in traditional dress explains how they were always prepared for attack. The hidden doors and secret passages are ingenious, but it can't have been a relaxed existence. Energetic demonstrations of ninja weapons like throwing stars, swords, daggers, and sickles are fun, and for an extra fee
you can try out the throwing star or even dress up as a ninja. One special exhibit gives you some background on ninja history and techniques, while another displays the disguises and encryption used here, as well as the inventive tools that enabled them to walk on water and scale sheer walls. The museum is in Ueno Park, a 10-minute walk up the hill from Iga Ueno Station.
