SECTION 1
Historical Context & Motivation
Asking questions about past events is one of the most fundamental acts of human communication. In every language and culture, people exchange stories about what happened, where it took place, when it occurred, and who was involved. In Japanese, this skill is especially important because the language structures questions and answers differently from English. Understanding these patterns opens the door to real conversation, from chatting with a host family about their weekend to discussing a movie with classmates.
The Japanese language has evolved over centuries, and its interrogative words (疑問詞 / ぎもんし) — words like 何 (なに/なん, "what"), どこ ("where"), いつ ("when"), and 誰 (だれ, "who") — have remained remarkably stable. Meanwhile, the verb conjugation system that marks past tense developed into its modern form during the Edo and Meiji periods. Today, combining question words with the past tense (〜ました / 〜た) is a core skill tested on proficiency exams and used in everyday life.

The central challenge for English speakers learning Japanese is this: Japanese question words do not move to the front of the sentence the way English "wh-words" do. Instead, you place the question word exactly where the answer would go and add the question particle か at the end. Mastering this word-order difference is the key to unlocking fluent question-and-answer exchanges about past narratives.

Core Principles & Key Vocabulary
Before diving into specific sentence patterns, you need to understand five foundational principles that govern how Japanese handles questions about past events. These principles apply whether you are speaking politely to a teacher or casually to a friend.

Visual Explanation — Question Word Placement
The diagram below illustrates the fundamental difference between English and Japanese question formation. In English, the question word jumps to the front of the sentence. In Japanese, it stays exactly where the answer information would appear. This "in-place" substitution is one of the most important structural insights for mastering Japanese questions about past narratives.
This pattern applies to every question word. Whether you ask about a place (どこ), a time (いつ), or a person (誰), the question word simply replaces the piece of information you want to know. The verb at the end stays in its past-tense form, and the particle か signals that you are asking a question.
SECTION 4
How It Works — Sentence Patterns for Past-Tense Questions
Now let's look at the four main question types you need for discussing past narratives. Each pattern uses a specific question word paired with a particle to ask about a different element of the story.
Pattern 1: What happened? — 何 (なに/なん)
WHAT-QUESTION PATTERN
何 (なに) = what · を = object particle · Verb〜ました = polite past tense · か = question marker. Example: 「何を食べましたか。」 = "What did you eat?"
Pattern 2: Where? — どこ
WHERE-QUESTION PATTERN
どこ = where · で = at (location of action) · に = to (destination/goal) · Use で with action verbs (食べる, 遊ぶ) and に with movement verbs (行く, 来る). Example: 「どこで勉強しましたか。」 = "Where did you study?"
Pattern 3: When? — いつ
WHEN-QUESTION PATTERN
いつ = when · Note: いつ typically appears at the beginning or right after the topic. It does NOT require a particle. Example: 「いつ日本に来ましたか。」 = "When did you come to Japan?"
Pattern 4: With whom? — 誰と (だれと)
WITH-WHOM PATTERN
誰 (だれ) = who · と = with (companion particle) · Example: 「誰と映画を見ましたか。」 = "With whom did you watch a movie?" Also: 「誰が来ましたか。」 (Who came?) uses が instead of と.

The following diagram provides a visual reference map that connects each question word to its function, its common particles, and a sample question-answer pair in the past tense. Use this as a study aid to see the full system at a glance.
| Question Word | Reading | Meaning | Key Particles |
|---|---|---|---|
| 何 | なに / なん | What | を, が |
| どこ | どこ | Where | で, に |
| いつ | いつ | When | — (none / に) |
| 誰 | だれ | Who | と, が, に |
| どう / どうやって | どう / どうやって | How | — (none) |

Worked Example — Asking Questions About a Short Narrative
Let's work through a complete example. Imagine your conversation partner tells you the following short narrative, and you need to ask follow-up questions to get the full picture. Here is the narrative:
The Narrative
Translation: "Last Saturday, I went to Shibuya with a friend. I ate ramen in Shibuya. It was very delicious." Now, let's practice forming questions about each element, then answering them.
Asking and Answering Questions About the Narrative
- 1
Step 1 — Ask WHEN (いつ)
We want to find out when the speaker went. We replace the time information (先週の土曜日) with いつ. Question: 「いつ渋谷に行きましたか。」 — "When did you go to Shibuya?"Answer: 「先週の土曜日に行きました。」 — "I went last Saturday." - 2
Step 2 — Ask WHERE (どこ)
We want to know where the speaker went. We replace 渋谷 with どこ and keep the particle に (destination). Question: 「先週の土曜日に、どこに行きましたか。」 — "Where did you go last Saturday?"Answer: 「渋谷に行きました。」 — "I went to Shibuya." - 3
Step 3 — Ask WITH WHOM (誰と)
We want to know who went along. We replace 友だち with 誰 and keep the particle と (companion). Question: 「誰と渋谷に行きましたか。」 — "Who did you go to Shibuya with?"Answer: 「友だちと行きました。」 — "I went with a friend." - 4
Step 4 — Ask WHAT (何を)
We want to know what the speaker ate. We replace ラーメン with 何 and keep the particle を (object). Question: 「渋谷で何を食べましたか。」 — "What did you eat in Shibuya?"Answer: 「ラーメンを食べました。」 — "I ate ramen." - 5
Step 5 — Ask HOW (どうでしたか)
Bonus question — we can ask about the speaker's impression. 「どう」 asks "how" in the sense of "how was it?" Question: 「ラーメンはどうでしたか。」 — "How was the ramen?"Answer: 「とてもおいしかったです。」 — "It was very delicious." (Note: おいしかった is the past tense of the い-adjective おいしい.)
SECTION 7
Polite vs. Casual — Choosing the Right Register
One of the defining features of Japanese is its system of speech registers. When you ask questions about past events, you need to choose between the polite form (〜ました + か) and the casual form (〜た + rising intonation or の). Your choice depends on your relationship with the listener and the social context. Using the wrong register can make you sound either stiff and distant or inappropriately casual.
| Feature | Polite (丁寧語 / ていねいご) | Casual (くだけた) |
|---|---|---|
| Verb ending | 〜ました | 〜た |
| Question marker | か at the end | Rising intonation ↑ or の |
| Example (What?) | 何を食べましたか。 | 何食べた? |
| Example (Where?) | どこに行きましたか。 | どこ行った? |
| When to use | Teachers, strangers, elders, workplace | Close friends, family, classmates |
| Particle を | Usually kept | Often dropped |

Connection to Advanced Communication
The question-and-answer patterns you have learned in this lesson form the foundation for much more complex Japanese communication. As you advance, you will encounter extended question forms, indirect questions, and narrative techniques that build directly on these basics.
| This Lesson (Beginner) | Next Level (Intermediate) |
|---|---|
| 何を食べましたか。 (Direct question) | 何を食べたか聞きました。 (Indirect: "I asked what they ate.") |
| いつ行きましたか。 (Simple when) | いつ行ったか覚えていますか。 ("Do you remember when you went?") |
| 誰と行きましたか。 (With whom) | 誰と行ったか教えてください。 ("Please tell me who you went with.") |
| どこで食べましたか。 (Where) | どこで食べたかによって… ("Depending on where you ate…") |
| Past tense: 〜ました | Past progressive: 〜ていました ("was doing") |
How beginner patterns scale to intermediate grammar
Notice the common thread: the intermediate forms embed the question clause (何を食べたか) inside a larger sentence. This is called an indirect question (間接疑問文 / かんせつぎもんぶん). The か at the end of the embedded clause no longer functions as a question marker directed at the listener; instead, it marks the clause as a "question content" noun phrase. Mastering the direct question patterns now will make this transition feel natural later.

SUMMARY
Lesson Summary
Summary
In this lesson, you learned how to ask and answer questions about past narratives in Japanese using four essential question words (疑問詞): 何 (what), どこ (where), いつ (when), and 誰 (who). The key structural insight is that Japanese question words stay in the same position as the answer information — they do not move to the front of the sentence like English "wh-words." The past tense (〜ました / 〜た) marks that you are discussing completed events, and the question particle か signals that you are asking rather than stating.
You also explored how particles (を, に, で, と, が) determine the precise meaning of each question and how the choice between polite (〜ましたか) and casual (〜た?) register depends on your relationship with the listener. These patterns form the foundation for all narrative discussion in Japanese — from simple weekend recaps to complex storytelling. Practice by retelling your own recent experiences and asking a partner to quiz you with these question patterns.
