All of the people inside the Senbon Torii can make you feel a bit claustrophobic. The trails in the surrounding forest are just the opposite. Among the mature trees and bamboo stands are thousands of small shrines. So consider exiting the Senbon Torii at the Yotsutsuji Intersection after about a 45 minute walk and then enjoying a tranquil descent. Shinto shrines began using tōrō lanterns during the Helan period (794-1185). The stone versions used in gardens are called dai-dōrō or ishi-dōrō.
