context_page_description: Mineoka Mountain District is an area in the Bōsō Hill Range in the southern part of Chiba Prefecture. The Mineoka Mountain District runs along an east-west line across the southern part of the Bōsō Peninsula from the southern bank of the Kamo River in Kamogawa, facing the Pacific Ocean, to the Sakuma District of Kyonan, facing Tokyo Bay. The highest peak in the mountain district is at Mount Atago 408.2 m Mineoka is formed from two kanji characters: the first "嶺", meaning 'peak' or 'summit' and the second "岡" meaning 'mount' or 'hill.'
context_section_description: The relative inaccessibility of the district, as well as its proximity to the capitol in Tokyo, led to the construction of military facilities at Mount Atago during World War II. The summit was confiscated by the United States Air Force, but was returned to the Japan Air Self-Defense Force (JASDF). It is now home to the strategically important JASDF Mineokayama Sub-Base.
