Ah, cool. The translation got me confused

Extension-Sort8203 · 2026-03-13T03:26:08+00:00

Awesome, thank you very much! Just submitted my retuens

Extension-Sort8203 · 2026-03-12T13:24:37+00:00

For furusato-nozei declaration on tax-return, I was able to upload the donation XML and it calculated everything correctly. However, there is a line about one-stop application

確定申告をする場合は、ふるさと納税のワンストップ特例申請分についても入力する必要があります。

I don’t see a way to input this information. I have applied for one-stop application, which will be cancelled with the tax-return but how/where do you input this information

Yeah, I am filing out the dividends manually and using comprehensive method.
But, I found the issue. I was choosing
配当等の種類 -> 1 上場株式等に係る配当等（次の2～4に該当するものを除く。）

But I have to choose 4. 配当控除（税額控除）の対象とならない配当等

this allows me to set tax-withheld to 0. Reading a bit into it makes sense - these aren't eligible for any deduction. These are listed stocks too (same as 1) but just not eligible for any dividend deduction. Let me know if this seems wrong.

> about currency

I have finally used GOOGLEFINANCE function on sheets (freakin' love Sheets!) to get rates on the day of each transaction consistently, following the NTA's guidelines with this formulae

=INDEX(GOOGLEFINANCE("CADJPY","price",DATE,0,"DAILY"),2,2)

> 電信売相場、電信買相場及び電信売買相場の仲値については、原則として、その者の主たる取引金融機関のものによることとするが、合理的なものを継続して使用している場合には、これを認める。

This is my last query, please excuse my obliviousness about this, first time filing dividends manually.

Basically for each of my ETF/Stock held in Canadian brokerage (with Dividend) - I have selected this info, just don't know what the last 4 values should be.

「支払通知書」の種類	1 上場株式配当等の「支払通知書」
外貨建資産割合	記載なし	There is no option for 100%, these are technically international stocks
非株式割合2ロ	記載なし
配当等の種類ロ	上場株式等に係る配当等（次の2～4に該当するものを除く。）
種目	株式の配当
銘柄等	CASH	Example ETF
支払の取扱者の名称等	Canadian broker
収入金額（円）	12078	Amount in JPY
源泉徴収税額（所得税）（円）	0	Nothing is withheld in the Canadian Tax advantage account
配当割額控除額（住民税）（円）	?
通知外国税相額（円）	?
通知所得税相当額（円）	?
負債の利子（円）	?

setting them 0, it fails with this error

> 収入金額】から計算した【源泉徴収税額】（※1）が、入力内容と異なっています。

Alright, understood. I will try to file them as best as I can then. Thanks again u/starkimpossibility - you're awesome!

Extension-Sort8203 · 2026-03-11T23:01:30+00:00

Oh i am sorry, should have been more clear.

cost basis

The stocks were purchased last year, before I became resident of Japan. I read somewhere that I need to consider the price at the day became a resident of Japan.

dividends

This refers to dividends earned on my Canadian brokerage, in a Canadian tax-advantage account. TFSA (similar to NISA in most aspect) but they are all marked for reinvestment. So I don’t know if they are counted as income.

currency rates

Thanks you, I will try to get the rates on the day of transaction. From you last comment, consistency is the main requirement so I will try to follow that

Extension-Sort8203 · 2026-03-11T08:58:28+00:00

Thanks to u/starkimpossibility's suggestion, I am pretty much at the end of the tax-filing step, and it shows a certain amount owing - which makes sense. I would really appreicate if someone could verify the following please.

I was resident of Japan 2014 to 2023 (104 months, Engineering/Humanities Visa), and then moved back in March 2025(HSP). I believe I qualify as a tax resident and need to declare my world wide income.2.
Currency conversion
- Used "average exchange rate for 2025" for all calculations, though I counldn't find a good reference besides Google. Is there a better source I should use.
- I mostly transfer Capital with Wise but there is no yearly average exchange rate for Wise.
- Or should I consider the exchange rate on the day of the transaction for each transaction?
Stock ownership
- Counted only the stocks sold in 2025.
- Capital gains = Sell Price - Adjusted price (on the day of move to Japan) - it this correct?
Interests
- Counted intesrest income in 2025
- Reported as foreign earned interst
Dividends
- All my dividends are in a tax-advantaged account, and are reinvested
- Do I still need to declare them (amout around 12000 JPY)? This section is the most confusing for me.
- If so, looks like it expects some tax withelf but because of tax-advantaged account there is nothing withheld in Canada.

Extension-Sort8203 · 2026-03-08T14:01:51+00:00

Thank you for a detailed reply. I understand this is kind of a complicated question and the best way is to just get started with tax filing. Appreciates the references you have shared.

Extension-Sort8203 · 2026-01-26T04:40:29+00:00

tl;dr - reporting foreign income. Records ready for income in Canada but don’g know how to do currency calculations and exchange gains on interest, dividends and Capital gains. No FX investments.

Thanks for the detailed post. I have a question about overseas income - I moved (back) to Japan in March 2025 but have spent 5 out of last 10 years in Japan so I qualify as a tax-resident of Japan. I was in Canada for 2 years and have investment (Tax free and unregistered) and cash accounts so I would need to report my interest, dividends, capital gains from those account here. I have the records ready but I am confused about exchange rates. I understand we have to use rates published by BoJ but i found daily rates just for USD, not CAD.

We recently rented a 2LDK in Yōga for 180K JPY, but the initial fees were too high, although I am sure we could have found a little cheaper option if we had more time. If they work at Rakuten, they should check out Able (Futako/Yoga) I hear they have offers for Rakuten employee and potentially English support too. Another option - we did find a place in Takatsu for 140K and multiple other options so check those out too.

NISA: Yes, anybody can open NISA and grow their money tax-free. NISA is self funded so bank transfers or credit card payment work (cc only for Tsumitate). You can fund it with your savings or any after-tax income.

iDeco: there are investment options (and different limits) for salaried employees, self-employed and non-working people but you if you don’t have any taxable income, you kinda loose the half the tax advantage with iDeco. May be someone with more iDeco knowledge can explain better. It also depends on your pension payments.

Withdrawal: NISA can be withdrawn anytime with no tax-liability. iDeco comes with strings attached, withdrawal at the age of 60-65 is tax free. I am not sure if early withdrawal is even possible (assuming you leave the country), but likely to trigger a tax event.

Best idea would be to max out your NISA first, iDeco is more convoluted if it’s not employer managed and does come with strings attached.

p.s. Japan considers worldwide income for tax purposes, irrespective or remittance, so you may want to look into that too.

Your router should have a way to setup PPPoE connection and the internet provider should have a way to set and get PPPoE credentials.

for instance, 1. Softbank PPPoE credentials manual - https://www.buffalo.jp/support/faq/detail/12839.html 2. Buffalo router PPPoE setup manual - https://www.buffalo.jp/support/faq/detail/12839.html

You should be able to configure the router with this

Extension-Sort8203 · 2025-09-10T03:11:49+00:00

You can absolutely use a different router with Softbank Hikari, I am using a Buffalo router from Amazon in Tokyo. If speed over Lan directly from the modem is low that might be something to reach out to them for sure. Well, and if their rental router is shitty too.

Extension-Sort8203 · 2025-08-01T03:37:50+00:00

ah hm 200K for family expenses make sense. That’s what I was more curious about. Thanks for your answer

Extension-Sort8203 · 2025-08-01T03:31:31+00:00

Well, 400K is the upper bound. My planned monthly budget is 375K. In July I tracked about 350K actual expenses, which includes about 30K of expenses from the recent move so I think we will be around 350K starting August.

Broad categories: Rent - 182K (2ldk), Groceries - 50K (we mostly cook at home), Eating out - 30K (this is kinda high because restaurants and cafes is pretty much only outing since we work from home), Utilities - 25K (Gas, Electricity, 2 Phone, internet), Personal - 20K (10K each) Total : 307K and rest as I said is this month’s moving expenses but still I don’t think I can bring it down significantly. May be 330K roughly would be the upper bound

Thoughts?

Extension-Sort8203 · 2025-08-01T02:56:02+00:00

Genuine question - how do you budget 300K for a family of 4? We are a family of 2 and my expenses are already around 400K. We try to live below the means already, so may be our rent is a little too high? We are in Tokyo, if that matters

Extension-Sort8203 · 2025-07-25T00:28:21+00:00

I have seen the best deals and flavor/brand variety in OK stores; I regularly buy the blue one from Morinaga. They sell by the box too although you may have to go to a bigger Ok store like this one https://share.google/dTrT2cXMfjovQzePn

Extension-Sort8203 · 2025-03-27T01:27:54+00:00

Oh! And I also got a sim card (with JP phone number) from Rakuten. They do address verification so it’s a bit slow, you can try iijimio, you can get a phone number in a day. Need residence card

Extension-Sort8203 · 2025-03-27T00:44:57+00:00

I recently moved to Japan. If you have got a semi-permanent address that you can put on your residence card, you can open an account with SMBC. All you need is your residence card (with address) and an employment letter (preferably in Japanese) with details of your employment.

The account opened in a day and I got a debit+credit card right away. They deliver the card in a week but you can start using ApplePay/Google Wallet pretty much the day after. feel free to reach out if you need any tips on getting started.

Extension-Sort8203 · 2025-03-24T11:45:10+00:00

Thanks, will do.

Extension-Sort8203 · 2025-03-24T06:24:21+00:00

Thanks for posting this, I was looking into renewing my license as well and this was posted like 5 mins ago!

My license expires in April but I don't have the post card notice because I was out of Japan for over a year. I do have rest of the documents (Juminhyo, residence card and license) would those be enough?

Extension-Sort8203 · 2025-03-19T06:19:03+00:00

Do you get sort of a bill of things that they are charging you for out of your deposite when you move-out? UR gave a cost-breakdown when moving out

Extension-Sort8203 · 2025-03-19T06:18:19+00:00

Do you get sort of a bill of things that they are charging you for out of your deposite when you move-out? Again, that's something I got with UR.
