Translation guide
Physiography refers to physical geography or geomorphology—the study of the Earth's physical features and processes. In Japanese, the most common equivalent is 自然地理学 (shizen chirigaku), but depending on context, related terms like 地形学 (chikeigaku) or 地文学 (chimon-gaku) may be used.
The branch of geography dealing with natural features and processes of the Earth's surface.
Standard academic term for physical geography, encompassing landforms, climate, soils, and vegetation.

Geomorphology; specifically the study of landforms and the processes that shape them. Often used when physiography focuses on terrain.

An older or more literary term for physical geography, sometimes used in historical contexts. Rare in modern usage.

A descriptive account of the physical characteristics of a region.
Natural geographical features; used when referring to the actual physical characteristics rather than the academic discipline.

自然地理学 (shizen chirigaku) is the broader field of physical geography, including climate, soils, and biogeography. 地形学 (chikeigaku) is specifically geomorphology, the study of landforms. Use 自然地理学 for general academic contexts, and 地形学 when emphasizing landform processes.
The English word 'physiography' is relatively rare and technical. In most cases, it's better to use the more common Japanese terms above rather than trying to transliterate or force a direct equivalent.
