Bring coins in small denominations (100-500 yen) if you plan to purchase ema plaques or make offerings, as the shrine is tucked between buildings in a shopping arcade rather than a spacious temple complex with multiple donation stations.
Visit on the first Friday of each month if you enjoy browsing secondhand goods and antiques, as the shrine transforms into a lively flea market with 30-40 vendors selling everything from vintage clothing to household items at bargain prices.
Buy a geisha-shaped ema plaque if you're praying for personal beauty, then draw in the face yourself before hanging it at the shrine, which is a unique local custom you won't find at other temples.
The temple houses a monument claiming to be the true grave of Tokugawa Ieyasu, based on a legend that he was killed during the 1615 Siege of Osaka and secretly buried here, contradicting official history.
