Ward office paperwork

Swap in the name of whatever procedure you're doing and these are ready to use.

1. 転入届てんにゅうとどけを出だしたいんですが。

   I'd like to file a move-in notification...

   You must file it within 14 days of moving; only after that can you enroll in health insurance, open a bank account, and update the address on your residence card.

2. 必要ひつような書類しょるいについて教おしえていただけますか。

   Could you tell me what documents I need?

   「〜について」 = "about something"; phrasing a question with it sounds more complete than directly asking 「何が必要ですか」.

3. この用紙ようしの書かき方かたが分わからないんですが。

   I'm not sure how to fill out this form...

4. 印鑑いんかんがないと手続てつづきできませんか。

   Can't I do the paperwork without a personal seal?

   Most procedures can now be done with just a signature, but it's safest to ask; 「〜ないと〜ない」 = "if you don't..., then you can't...".

5. マイナンバーカードも一緒いっしょに申請しんせいできますか。

   Can I also apply for a My Number card at the same time?

6. 受付うけつけは何時なんじまでやっていますか。

   What time does the reception desk close?

Take a number, hand over your residence card, ask about health insurance while you're at it, and find out how long the wait is.

1. clerk

   番号札ばんごうふだをお取とりになって、お待まちください。

   Please take a number and wait.

   「お取りになる」 is honorific language (it elevates the other person); for your own actions, use the 「お取りする」 pattern instead.
2. Applicant

   すみません、転入てんにゅうの手続てつづきに来きました。

   Excuse me, I'm here to do my moving-in paperwork.
3. clerk

   在留ざいりゅうカードをお預あずかりします。

   I'll hold on to your residence card.

   「お預かりします」 is humble language, a set phrase shop and office staff use when receiving something.
4. Applicant

   はい、どうぞ。国民健康保険こくみんけんこうほけんについても聞ききたいんですが。

   Sure, here you go. I'd also like to ask about National Health Insurance...
5. clerk

   それでしたら、手続てつづきが終おわってから、隣となりの窓口まどぐちへどうぞ。

   In that case, once we're done here, please head over to the next window.

   Japanese government offices run on a "one window per task" system, so being directed to another window is perfectly normal, not a sign that you're being given the runaround.
6. Applicant

   分わかりました。どのくらい時間じかんがかかりますか。

   Got it. How long will it take?
7. clerk

   混こんでいますので、三十分さんじゅっぷんほどお待まちいただくかもしれません。

   It's pretty busy right now, so you may have to wait about thirty minutes.
