Identify the question each time expression answers
Ask Mocchi for a small fictional comparison with a bus and train. Label the departure time and duration before deciding which is suitable. Read the label with the number rather than treating every time expression as interchangeable.
State the fictional meeting time as well. A shorter journey may not fit the arrangement if it leaves much later.
Learn the complete expression for duration
Use /vocab for a useful travel expression and /kanji for a complete-word reading where needed. Put the expression into a question or answer that identifies how long the journey takes.
Save a card if a useful duration expression needs later recall. Follow the card with a changed example so you can use it beyond the original number.
| Japanese | Romaji | Meaning |
|---|---|---|
| どのくらいかかりますか。 | Dono kurai kakarimasu ka. | How long does it take? |
| 三十分くらいかかります。 | Sanjuppun kurai kakarimasu. | It takes about thirty minutes. |
Compare the options using the stated information
Read a short fictional timetable or description. Identify which option has the shorter duration and which arrives in time for the meeting. Keep those as separate checks.
Use /quiz with changed times. Explain the relationship behind the answer. If a necessary detail is missing, write the question rather than inventing a timetable entry.
Ask and explain in AI Sensei
Prepare a suitable travel conversation with /kaiwa. In AI Sensei, explain the preferred option and listen to the follow-up. Ask about a missing time if it affects the decision.
Confirm whether the answer describes leaving or arriving. A short clarification can prevent a familiar number from being attached to the wrong event.

| Japanese | Romaji | Meaning |
|---|---|---|
| 何時に出発しますか。 | Nanji ni shuppatsu shimasu ka. | What time does it depart? |
| 何時に着きますか。 | Nanji ni tsukimasu ka. | What time does it arrive? |
Review the relationship rather than repeating every number
If the number was heard correctly but its role was misunderstood, focus on the question and label. If the role was clear but the number itself was missed, practise that listening distinction.
Bring the difficult turn to Mocchi and request a short focused exercise. Change the fictional time or duration so the next attempt requires interpreting the information again.
Transfer the distinction to another schedule
Compare two fictional class schedules or appointment options next time. Distinguish start time, duration and finish time before explaining the choice.
The connected platform makes number study useful across skills. Mocchi organizes the information, quizzes check understanding, and AI Sensei lets you practise discussing the choice and clarifying the reply.
