上田市塩田平の前山寺の裏にある弘法山はさほど大きくないけど頂上からの眺めは素晴らしい。それより、塩田城の名残りそして頂上付近の33石仏探検、無茶苦茶楽しい山です。私はアイゼンが必要ぐらいに雪が積もっていて尚スリリングでした。

Kobo-Yama is the smallish mountain behind national treasure Zenzan-ji Temple on Ueda City’s Shioda Plain. Despite its short stature the view from the summit is stunning but what makes Kobo-Yama distinct are the remains of the Warring State era Shioda Castle and the adventure of finding the 33 stone Buddhas tucked into crevices around the peak.

アクセス: お車なら前山寺は国宝なので沢山の看板が出てます。公衆トイレに広い駐車場あり。交通機関なら上田駅から別所線で塩田町駅、⑧信州の鎌倉シャトル線で前山寺バス停（本数と運行期間に限りあり）。　亀清旅館から車で20km、40分。戸倉駅から上田経由で塩田町まで約45分、バス20分又はタクシー5分。https://www.city.ueda.nagano.jp/uploaded/attachment/3023.pdf

ACCESS: By car, Zenzan-ji Temple is a National Treasure so well-signed. Use the large parking lot by the public toilet. By train, from Ueda Station take the Bessho Line to Shiodamachi and transfer to Bus #8 to the Zenzan-ji stop (frequency and operation limited). From Kamesei Ryokan, 20km (40 min.) by car. From Togura Station via Ueda 45 min. to Shiodamachi +20 min. bus or 5 min. taxi.

コース: 正面の登山口と塩田城経由の二つのコースがあるからループ可能。33石仏探しも含めて中嶋豊さんの「信州山歩き地図・里山編III北信東信」がマスト。COURSE: Two trailheads (official one above Zenzan-ji Temple and via Shioda Castle) so can be done as a loop. For both the course and for finding the 33 stone Buddhas, get Yutaka Nakajima’s 3rd hiking book.

いざ山城!　岩崎城経由で村上義清の葛尾城へ Samurai Forts: Climbing to Katsurao-jo via Iwasaki-jo

戸倉上山田温泉の近くの磯部地区から村上義清の葛尾城の登山道は米入り口コースの手前に岩崎城経由のコースもあって、先日に2人で登っでみた。岩崎城跡は整備されていないけど土橋や石垣が少し残っています。不思議な比丘尼(びくに)石や千曲川を見下ろせる絶景スポットがあって歯応えある山城ハイキングです。

Local samurai lord Murakami Yoshikiyo's main castle was Katsurao-jo, visible across the Chikuma River from our inn Kamesei Ryokan here in Onsen Town Togura-Kamiyamada.  From the nearby Isobe neighborhood, there are 2 trails to Katsurao-jo, one called the Kome-Iriguchi course that follows the old rear-entrance supply route, and one that passes by in intermediate fortress called Iwasaki-jo.  We recently hiked the latter.  Although hardly anything remains of Iwasaki-jo itself besides 'do-bashi' (earthen bridges) and some rock wall sections, the trail passes the mysterious Bikuni boulder and offers several panoramic viewpoints of the Chikuma River valley, so is well worth the climb.  (More info on Iwasaki-jo and Katsurao-jo from our friends at Jcastle.)

村上義清の奥さんが武田信玄の包囲攻撃から逃げた時に「ここで故郷の住民の永遠の幸せを祈願し化石となった」と書いてあります。When Takeda Shingen laid a siege to Murakami Yoshikiyo, he had his wife escape down this route.  According to legend, the princess stopped here and prayed for the local people so hard she turned into this rock.

アクセス　車で戸倉上山田温泉から国道18号を登って、「磯部南」信号の70m先に左曲がって、岩崎踏切でしなの鉄道を渡って、Yで右曲がって、登山口は約50mで右手に。バスは温泉や戸倉駅から路線バス⑧五加戸倉線で磯部ミニ公園で降りる。

Access: By car from Onsen Town Togura-Kamiyamada, take Route 18 south towards Sakaki / Ueda.  Pass the Isobe-Minami signal and in 70m turn left, cross the railroad tracks, at the Y turn turn right, and the trailhead will be on the right in about 50m.  By bus, from the onsen or Togura Station, take the #8 "Goka-Togura" bus and get off at Isobe Mini-Park stop.
