Local customs & good to know

• Onsen Etiquette Matters — Wash thoroughly before entering shared hot spring baths, remove jewelry, and follow posted gender-segregated bathing rules in traditional ryokan.
• Weather Changes Rapidly — Mountain conditions shift quickly; bring layers and waterproof gear even on clear mornings, as fog and rain can arrive suddenly.
• Silent Respect at Gassho-Style Prayer Sites — Several locations have small shrines and prayer spots reflecting both Buddhist and Christian traditions; observe quiet contemplation when others are present.
