Tenpakubara - Tenpakubara

This alluvial plateau lies in the southeast of Aichi Prefecture, south of Toyohashi City. It is the top of a three-tiered terrace on the left bank of the Toyokawa River and forms the base of the Atsumi Peninsula. It is adjacent to Takashibara across the Umeda River. The Pacific coast forms a linear cliff, and due to reverse tilt movement, the Pacific coast is high and slopes northward. The topsoil is highly acidic and poorly hydrated, making it unsuitable for cultivation and used as an army training ground. However, it was developed after World War II, and the poor water quality was eliminated after the opening of the Toyokawa Irrigation Canal. It is now a vegetable gardening area, and has become significantly residential due to the urbanization of Toyohashi City and the construction of Mikawa Port.

愛知県南東部、豊橋市(とよはしし)南部にある洪積台地。豊川(とよがわ)左岸の3段段丘上の最上位面で渥美(あつみ)半島の基部をなしている。梅田川を隔てて高師原(たかしばら)に隣接。太平洋岸は直線的断崖(だんがい)をなし、逆傾斜運動のため太平洋岸が高く北に向かって傾斜している。表土は強酸性、乏水性のため耕作に適せず陸軍演習地になっていたが、第二次世界大戦後開拓され、豊川用水の通水以後乏水性は解消され、現在は蔬菜(そさい)園芸地帯をなし、また、豊橋市の都市化と三河港造成の影響で住宅化が著しい。
