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”.
