Izumo Taisha — Ancient Shrine of Marriage & Destiny

Izumo Taisha is one of Japan's oldest shrines, maybe the oldest depending on who's counting. It's dedicated to Okuninushi, the kami of marriage, relationships, and agriculture. The shrine's shimenawa (sacred rope) in Kagura-den hall weighs 5.2 tons—Japan's largest, rewoven every few years by local volunteers using rice straw. You pray here with four claps instead of the standard two (two bows, four claps, one bow), a ritual specific to Izumo. The reason for four claps is debated—some say it represents the four seasons, others say you're clapping for yourself and your destined partner. According to Shinto belief, during the 10th lunar month (Kannazuki, 'month without gods,' everywhere else in Japan), all 8 million kami in Japan converge here for their annual meeting. In Izumo, that month is called Kamiarizuki ('month with gods'). The shrine's architecture is taisha-zukuri, a style older than Buddhist influence on Japanese shrine design—massive pillars, steep thatch, and proportions that feel ancient.
