Mount Tenpō, Artificial hill in Chikko, Osaka, Japan
Mount Tenpō is an artificial hill in Chikko near Osaka Harbor that rises only a few meters above the waterline and sits within a small park featuring lawns and shaded paths. The triangular mound is marked by a stone monument at its highest point, with trees and benches scattered around.
The mound formed in 1831 from earth excavated during dredging work on the Aji River and served then as a navigation aid for ships. Later the height dropped due to industrial changes and ground subsidence around the harbor area.
The low hill bears the name Tenpō after an era in Japanese history and once served as a coastal marker for ships. Today visitors gather at the summit and celebrate reaching the flattest peak in the region with souvenir photos.
The summit sits only a few steps from the park entrance and can be reached by a short flat path suitable for wheelchairs and strollers. The surrounding park grounds offer rest areas and connect easily with other destinations along Osaka Bay.
The Geographical Institute of Japan lists the hill at 4.53 meters (15 feet) as an official mountain in its records, making it one of the lowest registered mountains in the world. Despite the modest height, visitors can receive a summit certificate.
