Tonai-kabe (藤内壁), the granite crag on the north face of Mt. Gozaisho in Komono, Mie, is known for long multi-pitch lines on Maeone and Nakaone. ROCKTOPO lists 124 routes (79 face, 36 crack, 9 multi-pitch), and both Japanese sites give April–November as the season. Take the Kintetsu line to Yunoyama-Onsen Station, a bus to the Gozaisho Ropeway stop, then about an hour up the Ura-michi trail past Tonai Hut.
A tuff crag in Izunokuni, Shizuoka. ROCKTOPO lists 362 routes (334 single-pitch, 28 multi-pitch) and CLIMBING-net says about 300, most of them 5.10–5.11. ROCKTOPO gives the season as November–March, CLIMBING-net as late September to early June; the trailhead is about a 25-minute walk from Ohito Station on the Izuhakone Railway.
A chert crag in Ohara, Sakyo Ward, Kyoto: CLIMBING-net says about 70 routes, ROCKTOPO lists 49, most at 5.10 or below, and the walls link into a north-ridge multi-pitch. Neither site gives month-by-month reasons; CLIMBING-net lists it as year-round. Take the Kyoto Bus to Hanajiribashi or Todera and walk about 20 minutes to Ebumi Shrine — never park at the shrine.
A granite crag in Hokuto, Yamanashi: ROCKTOPO lists 733 routes (371 cracks, 128 multi-pitch) plus 539 problems at Mizugakiyama Boulder. Season is April–November and the forest road closes in winter. The seasonal bus from JR Nirasaki Station does not reach the Mizugakiyama Nature Park where climbers park.
White granite sea cliffs in Otsuki, Kochi. ROCKTOPO lists 85 routes, 75 of them cracks, and apart from anchors on the popular lines there is almost no fixed gear, so bring a rack and build your own anchors. Both sites give the season as November to March; the cliffs face south and get hot even in winter when the wind drops. The rail line ends at Sukumo Station on the Tosa Kuroshio Railway, and every source assumes you drive from there.
