"Mainland Japan" (内地, naichi, lit. "inner lands") is a term used to distinguish Japan's core land area from its outlying territories. It is most commonly used to distinguish the country's four largest islands (Hokkaidō, Honshū, Kyūshū, and Shikokū) from smaller islands such as the Bonin Islands and the Ryukyu Islands. However, depending on the context, the term "Mainland Japan" may refer only to Honshū, the largest island.

The term's literal Japanese meaning might best be translated as "inner Japan" or "inner lands". The term "mainland" is somewhat inaccurate since it usually refers to all or part of a continental landmass, rather than islands.

"Mainland Japan" was an official term in the pre-war period, distinguishing Japan proper from its colonies in the Far East (which at that time included parts of mainland Asia). After the end of World War II its usage became less common and lost its previous legal significance.
