Summary: Steady uphill slog with beautiful views on clear days. Easy to get to, and the udon on top is certainly worth the 1000¥!
The hike: A popular hike that can be accessed from various access points, this will not be a solitary experience on weekends. However, as it is quite the uphill slog, you'll usually only find groups of enthusiastic hikers (rather than the city slickers looking to instagram their outdoor adventure on Takao).
This peak can be bagged as part of a longer Tanzawa ridge traverse, but it's proximity to Tokyo and the amazing lunch option at the top make it great as a standalone hike. Though this hike can be done year round, you might need some light crampons if there has been snowfall in Tokyo, and longer hiking socks/pants are recommended to avoid leeches in the summer.
The trickiest part is find the trail head from Ookura bus stop. The bus stop is a bustling hub for hikers and has all the amenities (including shoe washing stations). Make sure you fill up on water here as there are no water access points on the trail (even at the top). There are many trails that start here and hikers dispersing in all different directions. You'll want to follow most of the crowd and head on the trail towards Tonodake （塔ノ岳）. To get to the trailhead, you'll be passing north through the little farming village. There will be turnoffs heading towards a camp ground and a path that looks like a trail, but ignore these. The real trailhead is clearly marked with a sign (there are also signs on the road pointing towards the trailhead).
The turn off for Nabewari-yama (鍋割山) is at about the 3 hour mark. You want to head in the direction of 大丸・小丸・鍋割山. From the turnoff it's another hour to the summit of Nabewari. There's quite a nice story about Kusano-san, the owner and operator of the hut at the summit of Nabewari, which you can read about in more detail in some of the other blog posts about this hike (found in the links below). Make sure you put your order for udon in as soon as you get to the top, as it takes a bit of time to prepare!
For the trip down you can retrace the same route you took up, or take an alternate route which will lead you to the 寄自然休養村管理センター bus stop (寄) for buses heading towards Shin-Matsuda （新松田） station. The hike from the summit to the bus stop is about 2 hours.
Take the bus from the North exit of Shibuswa station. It will be at bus stop #2, heading for 大倉 (ookura). The bus timetable can be found on the Kanazawa transportation website (https://www.kanachu.co.jp), which can be accessed here (make sure you make note of differing weekday and weekend times!)
For buses back from 寄自然休養村管理センター (the bus stop is called 寄) you can find timetable information for the 寄 to 新松田駅 bus route on the Fujikyu bus website (http://www.syonan-bus.co.jp/). Bus schedule can be found here, though this is subject to change annually. The bus costs 540¥.
