Frequently Asked Questions
How long is the climb to the Honguu summit shrine?
The main hall (Shimomiya) is reached after 837 stone steps from the coastal road — roughly 20 minutes. The Honguu inner sanctuary sits about 500 m up and requires a further 40-minute hike on a steep forest trail. Water, a hat, and sturdy footwear are essential.
Why is Izusan called Hashiriyu Gongen?
The name refers to the 70 °C hot spring that gushes from the mountainside and “runs” down to the sea. This Hashiriyu is enshrined as Hashiriyu Shrine and is historically the origin of Atami’s famous hot springs.
What is the best season to visit?
Autumn (October–November) offers cool temperatures and morning fog over the bay. Cherry blossom season (late March–early April) is beautiful but crowded. Weekday mornings year-round are consistently quietest.
Can I receive a goshuin (red-stamp certificate)?
Yes. The shrine office is open approximately 8:30–16:00. Several designs are available, drawn from the Yoritomo-Masako tradition and the Hashiriyu Gongen motif. Hand-written on weekdays; stamped booklets available when busy.
