Tanzawa’s gentle natural beauty awaits,
with sunbeams streaming through the fresh green Buna tree leaves (Japanese beech (Fagus crenata Blume))
in early summer and the soft glow of multihued autumn leaves later in the year

Geographical/topographical features
This area is located in northwestern Kanagawa Prefecture. Although it is in the Tokyo suburbs, a virgin forest still remains. The rich forest, the eroded rocks distinctive of the Tanzawa Massif, steep valleys and numerous waterfalls are wonderfully harmonious and provide tourists with varied seasonal experiences.
Historical/cultural features
Roben Shonin, the first head priest of the Todaiji Temple in Nara, founded a temple in this area in the middle of 8th century. The Tanzawa massif has been a training ground for hermits and ascetics and a sacred place for mountain worship ever since. Worshippers actively made pilgrimages, particularly to Mt. Tonodake and Mt. Oyama, which were centers of mountain worship.
Because of this, many mountain names and place names in this area are related to religion, such as Mt. Gyoja, Mt. Sonbutsu, Yakushi, Bodai and Orondo.
Climate, flora and fauna
This area is close to the Sagaminada Sea and has a maritime climate in which fog occurs very frequently. Fog sometimes forms in the morning even on sunny summer days. The average temperature is around 15°C at the foot of the mountains, 12–13°C midway up the slopes of the mountains, and a very low 7°C at their summits.
The area is home to temperate and warm temperate vegetation. Evergreen broad-leaved trees, such as live (evergreen) oak and Sudashii (Castanopsis sieboldii), and conifers such as Momi (fir (Abies firma)) and Tsuga (Japanese hemlock (Tsuga sieboldii)) grow in some low-elevation areas, while Buna (Japanese beech (Fagus crenata Blume)), Mizunara (Japanese oak mizu-nara (Quercus crispula Blume) and maple (Acer) grow in higher-elevation areas.
A variety of animals inhabit the area, including Nihonjika (shika deer (Cervus nippon)), Nihon Zaru (Japanese macaque (Macaca fuscata)), Nihon Kamoshika (Japanese serow (Capricornis crispus)) and Tsukinowaguma (Asian black bear (Ursus thibetanus)). While the number of shika deer has grown too large and there is a need to reduce their numbers, only around 30 Asian black bears live throughout the Tanzawa Mountains and they are in danger of extinction.
This area features a beautiful virgin forest with abundant tree species and magnificent views from the Tanzawa Mountains. The view of the vast Kanto Plain spreading to the east, the deep-blue Pacific Ocean to the south and sacred Mt. Fuji rising in the west is majestic and stunning.
A growing number of tourists have in recent years begun visiting this area not only to experience nature and for camping and hiking, but also for serious trekking.
The natural springs of the Hadano Basin at the foot of the mountains have been chosen as one of Japan's 100 Selected Water Spots. The Gomayashiki water spot, Kuzuha water spot and Ryujin spring are particularly famous, as is the Kobo spring near Hadano Station, which has a legendary association with famous Buddhist monk Kobo Daishi.

  • Yabitsu Pass: 37 minutes by car from the Okura bus stop. The pass is very popular with hikers on holidays because of the Kanagawa Chuo Kotsu bus route to Yabitsu Pass from Hadano Station on the Odakyu Odawara Line and mountain trails leading to Mt. Tonodake (Omote ridge) and Mt. Oyama from the pass.
  • Mt. Oyama: 41 minutes by car from the Okura bus stop. Mt. Oyama has been regarded as a sacred mountain since ancient times, and Jomon pottery from the Mesolithic period believed to have been used for rituals has been excavated at its summit. Because clouds and fog often formed on the mountain and brought rain, Mt. Oyama was also referred to as "amefuri" (rainy) mountain, and people prayed to it for rain.
