Whatever the belief system or whoever they're devoted to, shrines have a way of making you contemplative. Visit Izumi Shrine and share a moment of silence with the locals.
This sacred place in Komae is popular with travelers, so make a spot for it on your travel itinerary. Don't think that's all there is to do here, though. There are loads more options waiting for you to discover after Izumi Shrine. Museum of Japanese Houses, Ghibli Museum, and Yomiuriland are nearby.
