Oinosaka - Oinosaka

A pass in the Oeyama mountain range between the Kyoto Basin and the Kameoka Basin in the southwest of Kyoto Prefecture. It is 193 meters above sea level. It is also called Oeda Pass. Until the Edo period, the San'in Road was the only transportation route connecting Kyoto and the Tamba area, and it is said that Oe Barrier was already established in 679 (the 8th year of Emperor Tenmu's reign) as a transportation and military strategic point. The whole area was called Oedayama, and the Oeyama in Koshikibu no Naishi's "Oeyama Ikuno no Michi no..." is also interpreted as referring to Oinosaka, and Akechi Mitsuhide also set out from here to attack Honnoji Temple. When the San'in Main Line was opened in the Meiji period, the transportation value of the pass temporarily declined, but in the Showa period it became an important transportation route again. Currently, National Route 9 passes through a tunnel in place of the old road, and automobile traffic is frequent.

京都府南西部、京都盆地と亀岡盆地との間の大枝(おおえ)山山塊にある峠。標高193メートル。大枝峠ともいう。江戸時代まで京都と丹波(たんば)方面を結ぶ唯一の交通路として山陰道が通じ、交通、軍事上の要衝として、679年（天武天皇8）すでに大江関が置かれたと伝えられる。一帯は大枝山とよばれ、小式部内侍(こしきぶのないし)の「大江山いく野の道の……」の大江山は、この老ノ坂をさすとも解され、明智光秀(あけちみつひで)もここから本能寺攻めに向かった。明治になって山陰本線が開通し峠の交通的価値は一時衰えたが、昭和に入りふたたび重要な交通路となった。現在では旧道にかわって国道9号がトンネルによって通じ、自動車の往来が頻繁である。
