Questions & Answers about watashi wa ichido nihon ni ikitai desu.
は marks the topic of the sentence: what we’re talking about.
が usually marks the grammatical subject, especially when introducing something new or focusing on who did something.
In this sentence:
- 私 は 一度 日本に 行きたい です。
→ “As for me, I want to go to Japan once.”
Using は makes 私 the general topic: “speaking about me…”.
If you said 私が一度日本に行きたいです, it would sound like you’re contrasting yourself with others or emphasizing “I’m the one who wants to go” (e.g., not someone else). That nuance is usually unnecessary here, so は is the normal choice.
Yes. In natural Japanese, the subject is often omitted when it’s clear from context. You could simply say:
- 一度 日本に 行きたいです。
→ “(I) want to go to Japan once.”
This is very natural, especially in a conversation where it’s already clear that you’re talking about yourself.
You might explicitly say 私 if:
- You’re introducing yourself for the first time.
- You want to contrast with someone else (e.g., “I want to go, but my friend doesn’t”).
- You’re practicing and want to see the full structure.
Literally, 一度 means “once / one time”.
In this sentence, it has two overlapping nuances:
- Literal: “I want to go to Japan once (at least one time).”
- Idiomatic: It often carries a softer, “sometime (in my life)” feeling, similar to:
- “I’d like to go to Japan at least once.”
- “I’d like to go to Japan someday (at least once).”
So it keeps the idea of “at least one time,” but in many contexts it feels like “someday, at least once in my life.”
If you want a more open-ended “someday” without the “once” nuance, you can also say:
- いつか 日本に 行きたいです。
→ “I want to go to Japan someday.”
に is a particle with several uses; one of them is to mark the destination of movement.
With verbs like 行く (to go), 来る (to come), 帰る (to return), you usually use に (or へ) to show where you’re going.
- 日本 に 行きたいです。
→ “I want to go to Japan.”
So here に = “to (a place)” in English.
Note: に can also mean “in/at/on” for locations and times, but in this sentence it’s the destination marker.
You can absolutely say:
- 日本へ 行きたいです。
Both are correct and natural.
に vs へ with motion verbs:
- に focuses more on the destination as a place you end up at.
- へ focuses more on the direction / movement toward that place.
In modern everyday Japanese, 日本に行きたいです is more common, but 日本へ行きたいです does not sound strange.
In many basic sentences, you can treat them as more or less interchangeable, and に is a bit safer as a default.
The base verb is 行く (iku) = “to go”.
To say “want to do X” with most verbs, Japanese uses the 〜たい form:
- Take the ます-stem of the verb.
- 行く → 行き (this is the same stem used in 行きます)
- Add たい.
- 行き + たい → 行きたい = “want to go”
So:
- ❌ 行くたい – incorrect form
- ✅ 行きたい – correct “want to go”
Then to make it more polite, you can add です, because 〜たい behaves like an i-adjective:
- 行きたい (casual)
- 行きたいです (polite)
Literally, 行きたいです is “(I) want to go.”
However, nuance-wise:
- In polite Japanese, 〜たいです is not as blunt as “I WANT to …!” in English.
- It’s usually felt as a normal, polite way to express your desire: somewhere between “I want to go” and “I’d like to go.”
If you want to be even softer or more indirect, you might use patterns like:
- 日本に 行けたら いいな と思います。
“I think it would be nice if I could go to Japan.” - 日本に 行ってみたいです。
“I’d like to try going to Japan (at least once).”
But in most everyday contexts, 日本に行きたいです is already polite and not overly pushy.
行きたい is based on the verb 行く, but 〜たい itself behaves grammatically like an i-adjective (like うれしい, たのしい, etc.).
- Casual: 行きたい。
- Polite: 行きたいです。
Adding です:
- makes the sentence polite (です/ます style),
- is standard for talking to strangers, teachers, in most formal situations.
So 行きたいです is simply the polite form of 行きたい. Both are correct; which one you use depends on formality and relationship with the listener.
Both are possible:
- 一度 日本に 行きたいです。
- 日本に 一度 行きたいです。
In this sentence, both sound natural. Japanese word order is relatively flexible; the crucial part is usually:
- verb at the end: …行きたいです
Elements like 一度 (once) and 日本に (to Japan) can swap positions without changing the meaning much.
Subtle nuance:
- 一度 日本に 行きたいです。
Slightly emphasizes “once (in my life), to Japan…” - 日本に 一度 行きたいです。
Slightly emphasizes “to Japan, once…”
But in everyday conversation, the difference is minor; both are fine.
- 私 – わたし (watashi)
- は (topic marker) – pronounced わ (wa), not ha
- 一度 – いちど (ichido)
- 日本 – commonly にほん (Nihon); にっぽん (Nippon) is also correct but used in specific contexts (e.g. official names, cheering). Here にほん is more usual.
- に – に (ni)
- 行きたい – いきたい (ikitai)
- です – usually pronounced です (desu), with the u very weak or almost silent in natural speech: sounds close to des.
私 (watashi) is:
- gender-neutral in polite speech (men and women both use it),
- slightly more common for women in casual speech, but that’s more about informality.
In a polite context, a man can naturally say:
- 私 は 一度 日本に 行きたいです。
In casual or very informal speech, men often switch to:
- 僕 (ぼく) – common, softer:
僕は一度日本に行きたい。 - 俺 (おれ) – rougher / more masculine:
俺は一度日本に行きたい。
So the sentence as given is perfectly fine for any gender in polite situations.
Use the negative of the 〜たい form:
- 行きたい → 行きたくない (“don’t want to go”)
Polite form:
- 行きたくないです or 行きたくありません
So the full negative sentence is:
- 私は 日本に 行きたくないです。
→ “I don’t want to go to Japan.”
(Again, 私 can be omitted if it’s clear from context.)
