Near the towering apartment buildings in Tokyo's Tsukuda area is a blink-and-you'll-miss-it alley. But tucked away down the narrow passage is a stone carving of a Buddhist guardian deity and a centuries-old ginkgo tree. Some people come to this small, secluded site to pray for good health, others for business prosperity or a better relationship with their spouse. Some just drop by to clear their mind. For 3 days, we asked visitors why they come to this unique spot loved by locals for almost 300 years.
