If you are not a US Citizen (or Green Card Holder), then you will be taxed in the US on Dividends by Withholding, but not on Capital Gains.
You have to claim the Foreign Tax Credit against your Japanese Taxes on the Kakutei Shinkoku Form B - Page 1 - Item 46.
For Dividend Income
You need to file a W8-BEN Form with your broker to claim the benefit of the US-Japan Tax Treaty.
If you do not file a W8-BEN or if your broker doesn't file your W8-BEN correctly on your behalf, then you will be subject to US Withholding Tax at 30%.
If you correctly file the W8-BEN, under the US-Japan Tax Treaty you will only be subject to US Withholding Tax at 10%. This tax is payable to Uncle Sam for US derived income.
Any Foreign National (non-US Citizen), including Japanese, who is filing a W8-BEN should in Part II state:
Part II Claim of Tax Treaty Benefits (for chapter 3 purposes only) (see instructions)
9. I certify that the beneficial owner is a resident of ___JAPAN___ within the meaning of the income tax treaty between the United States and that country.
10. Special rates and conditions (if applicable—see instructions): The beneficial owner is claiming the provisions of Article and paragraph
_10 2(b), 11 2(b)_ of the treaty identified on line 9 above to claim a ___10___ % rate of withholding on (specify type of income):
___Dividend and Interest Income___
Explain the additional conditions in the Article and paragraph the beneficial owner meets to be eligible for the rate of withholding:
___As A Resident Of Japan for Tax Purposes.___
The Broker will then withhold US Tax due to Uncle Sam at 10%
In Japan, you need to file a Kakutei Shinkoku by Mar 15, and you need to select the Separate Self-Assessment Taxation method (Form B - Pages 1&2 And Page 3).
Under the Separate Self-Assessment Taxation method, you will be liable to 20.315% Dividend Tax (15% National, 0.315% Reconstruction, and 5% Residential Taxes).
You should then receive a 1042-S Statement of US Taxes Withheld from your broker, around the beginning of April, in time for US Tax Filing (Apr 15).
You can then revisit and amend your Kakutei Shinkoku and claim the Foreign Tax Credit for the 10% Tax paid in the US - Form B Page 1 - Item 46.
So then your taxes become 10% US Withholding, 5% National, 0.315% Reconstruction, and 5% Residential Taxes.
