Sangun Mountains

Japanese: 三郡山地 - さんぐんさんち
Sangun Mountains

A 60-kilometer arc-shaped mountain range stretching from the Munakata coast to Mt. Hidehiko (1,199 meters) in the southeast in central Fukuoka Prefecture. It is part of the Tsukushi Mountains. The mountain range is made up mainly of Mesozoic granite and Mt. Migun metamorphic rocks, with Mt. Nishi (645 meters), Mt. Hokotate (663 meters), Mt. Homan (869 meters), Mt. Kosho (860 meters), and Mt. Umami (978 meters) lining up from the north, dividing Fukuoka Prefecture into east and west. Because it is a fault mountain range, it has long been a traffic hazard despite its altitude, but now the main roads cross Inunaki Pass (367m), Yagiyama Pass (228m), and Hiyamizu Pass (283m) to connect the Fukuoka and Chikuho districts, while the JR Kagoshima Main Line, Sasaguri Line, and Chikuho Main Line also pass through it through tunnels, overcoming these obstacles. Cedar tree planting is progressing south of Inunakiyama, and the mountains of Sangun and Homan are included in Dazaifu Prefectural Natural Park, and the area around Furushiroyama is included in Chikugogawa Prefectural Natural Park, so there are many hikers.

福岡県中部を宗像(むなかた)海岸から南東方英彦(ひこ)山(1199メートル)まで約60キロメートルの弧状に続く地塁状の地塊山地。筑紫山地(つくしさんち)の一部をなす。かつての糟屋(かすや)、筑紫(ちくし)、嘉穂(かほ)の3郡の境界に位置する三郡山(936メートル)を主峰とし、おもに中生層の花崗(かこう)岩や三郡変成岩からなる山地で、北から西(にし)山(645メートル)、鉾立(ほこたて)山(663メートル)、宝満(ほうまん)山(869メートル)、古処(こしょ)山(860メートル)、馬見(うまみ)山(978メートル)などが並び、福岡県を東西に分ける。断層山地であるため高度のわりには古くから交通障害となってきたが、現在では主要道路が犬鳴峠(いぬなきとうげ)(367メートル)、八木山峠(やきやまとうげ)(228メートル)、冷水峠(ひやみずとうげ)(283メートル)を越えて福岡地区と筑豊(ちくほう)地区を結ぶ一方、JR鹿児島本線、篠栗(ささぐり)線、筑豊本線もトンネルで貫通して障害を克服しつつある。犬鳴山以南ではスギの植林が進み、三郡、宝満の山々は太宰府(だざいふ)県立自然公園、古処山一帯は筑後川(ちくごがわ)県立自然公園に含まれ、ハイキング客も多い。
