Mount Takao offers different trails and levels of difficulty, so it's up to you to decide how you want to climb it. You can also take the chair lift to the top and enjoy the stunning view.
On a sunny day, you can easily see Mount Fuji. The view is simply breath-taking and was worth the effort.
There's also a temple at the top for you to visit. Also, on your way back, very close to the station, there's a recently built "onsen" (hot springs). There's really nothing more relaxing than stepping into a hot bath after a long day.
When climbing Mt Takao, the classic meal to have is soba.
Takashiya is located on Mt Takao and was established in 1830. They have delicious tempura soba or you can also try the tororo soba. Tororo is a Japanese mount yam that is grated to form a paste, it is slightly slimy, but it gives the soba a delicious light taste.
A bowl of soba starts at ¥650, or you can have a course from ¥2,800.
Sakaechaya is also located on Mt Takao and specialises in soba. You should try the fungus soba (mushroom), it is a really delicious way to get the energy you need to climb the mountain. They have an English menu. The restaurant is often quite packed, so you might have to wait a little before being seated.
Ukai Toriyama is a wonderful restaurant to visit after hiking Mt Takao. It is also very convenient to get to as there is a shuttle bus picking you up from Takaosanguchi station taking you directly to the restaurant. The lunch course is around ¥5,000 and the dinner course starts at about ¥6,000. Imagine walking into a beautiful restaurant surrounded by greenery and with a gorgeous garden, and then sitting in a tatami room to enjoy a delicious course. Definitely a must-try!
If you're looking for something a little more upscale, the sister restaurant of Ukai Toriyama, Ukai Chikutei is the place to go. They can also pick you up by shuttle from Takaosanguchi station to take you directly to the restaurant. They have a Japanese style garden with a tea room and a koi carp pond. If you're looking for a traditional Japanese setting, this is the place to visit. The restaurant serves "kaiseki ryouri" (Japanese style course) from around ¥5,000 for lunch, and ¥7,000 for dinner. The menu changes seasonally so you will have a different experience depending on the time of year you go!
Gonsuke is close to Takaosanguchi station and is a BBQ restaurant. You order the type of vegetables and meat you want to grill and you cook yourself at the centre of the table. It really is a fun activity after a long day of hiking. As you talk away with your friends, you grill your food and chug down a cold beer. The food is great and the price is reasonable.
Mount Takao is a wonderful place to visit to forest bathe and there are many wonderful restaurants to visit. If you're on a budget, soba is a great and cheap option. And if you want to splurge a little and have a wonderfully traditional Japanese experience after a long day of hiking, the course meals are great!
