What is the Mashita Form?
The ました form is how you talk about the past politely in Japanese. It's the polite past. Used for everything from "I ate lunch" to "I studied abroad for three years" when speaking to someone you're not super close with. Our lesson on Japanese past tense covers ました and ませんでした with plenty of practice.
If you know ます form, making ました is dead simple: swap ます for ました. Same stem, different ending.

Mashita vs Ta-Form
Same meaning, different politeness:
- 食べました — polite (for strangers, work, formal situations)
- 食べた — casual, using the た form (for friends, family, inner monologue)
Both mean "ate." The choice depends entirely on who you're talking to, not what you're saying.
When to Use
- Recounting events to a teacher, boss, or stranger
- Formal storytelling or presentations
- Customer service interactions
- Any time you'd use ます form but for past events
