In Japanese grammar, discussing age involves using specific vocabulary, sentence structures, and the unique counter for age – « さい » (sai). The most common way to ask someone’s age is by using the question « 何歳ですか? » (Nansai desu ka?), which means « How old are you? ». When answering, one must state their age plus the counter « さい ».
