noun
antipodes; antipodal point
Geographical term for the point on the Earth's surface diametrically opposite to another. Often used in the phrase 対蹠点にある.

From 対 (opposite) + 蹠 (sole of the foot, here meaning 'place') + 点 (point). The reading たいせきてん uses the kan'on reading of 蹠, while たいしょてん uses the goon reading.
