Learner Tips
A common mistake is to confuse 土台 with 基礎 (きそ), which also means foundation. While both can be used for physical and abstract foundations, 土台 often emphasizes the base or platform that supports something, whereas 基礎 can refer more broadly to basic principles or fundamentals. Use 土台 when focusing on the supporting base or groundwork.
