Overview (history, characteristics, attractions)
Mount Nantai is a stratovolcano located in Nikko City, Tochigi Prefecture, at an elevation of approximately 2,486m, and is the central figure in the Nikko mountain range. It has been an object of mountain worship since ancient times, and as Mount Futarasan it has a deep connection with Futarasan Shrine (Chugu Shrine and Main Shrine). Rising right next to Lake Chuzenji, it is a popular scenic spot offering panoramic views of the lake and Oku-Nikko, and is particularly attractive for hiking from spring to autumn and for viewing the autumn leaves. It is also a sacred mountain, mentioned in connection with the scope of the "Shrines and Temples of Nikko" World Heritage Site in 1999.

Things to be aware of (crowds, manners, seasonal precautions, etc.)
- Crowds: It gets very crowded during the autumn foliage season (usually mid- to late October), Golden Week, and weekends. Parking lots and buses tend to get crowded, so it's recommended to leave early.
- Climbing difficulty and equipment: Due to the large elevation difference, steep climbs, and rocky areas, be sure to bring hiking boots, rainwear, cold weather gear, a headlamp, and plenty of food and drink. Even in summer, it can get chilly in the mornings and evenings.
- Winter: Due to heavy snowfall and ice, crampons and ice axes may be necessary. Climbing in winter is for advanced climbers, and routes and road closures may occur.
- Health management and activity plan: Due to the large difference in altitude, there is a risk of altitude sickness. Do not push yourself, take frequent breaks, and stay hydrated. Avoid hiking alone, and be sure to submit a mountain climbing notification and mountain climbing plan, or inform your family and accommodation of your itinerary.
- Toilets and shops: There are limited toilets and shops at the summit and along the way, so be sure to prepare anything you need in advance. Be sure to take your trash with you (nature conservation and etiquette).
- Consideration as a place of worship: This mountain has a deep connection with Futarasan Shrine. Please observe proper etiquette on the hiking trails and around the shrine, such as not shouting or littering within the grounds.
- Check mountain climbing information: Be sure to check the weather forecast and mountain trail information (road closures and falling rocks) before setting off.
For reference, beginners to intermediate hikers can do this as a day trip depending on the weather and equipment, but we strongly recommend planning well in advance and taking the appropriate equipment and preparation. With safety as your number one priority, enjoy the scenery of Oku-Nikko, Lake Chuzenji, and the charms of Mt. Nantai.
