Japanese Masu Form: Present and Future Polite Verb Conjugation
The ます form is the polite non-past verb form, so it can mean either present or future depending on context. 食べます can mean “I eat” or “I will eat.” Group 1 verbs change to the い-row + ます, Group 2 verbs drop る, and Group 3 verbs become します/きます.
If you are searching for the Japanese “future tense” with ます, this is the key point: Japanese usually uses the same ます form for present and future, and context tells you which one is meant.
