Hi Ben,
The devil, as always, is in the detail.
There is no Y200,000 Allowance on which you do not need to pay tax. It's just that you don't need to file a return for up to Y200,000 in Income other than Employment Salary Income So Long As Japanese Tax has been Withheld at Source. Any Income that was not subject to Japanese Tax Withholding at source must be filed and taxes must be paid.
In Japanese Tax Law, Miscellaneous Income is actually a category of income that is not covered by the other classifications of Income.
However, in your mail, I think you mean to use 'miscellaneous' to mean any/all kinds of Income except employment salary income.

1. Persons with the Employment Income
*For most people, the income tax etc. is settled by the “year-end adjustment” of employers, so the final return is NOT necessary. If you file a final return, it is required to include salary income that received year-end adjustment in the return.
You ARE required to file a final return if;
(1) Your total amount of the earnings of salary etc. exceeds 20,000,000 yen.
(2) Your total amount of income (except for the employment income and the retirement income) exceeds 200,000 yen when the salary etc. (INCOME OF ALL KINDS) is received from one source only and ALL of the salary etc. (INCOME) is subject to the Japanese withholding.
Don> 'Subject to Japanese Withholding' excludes Foreign derived income which has not been subject to Japanese Withholding. See 5 below
Don> Note that US or other country's withholding is for that country's tax liability and not for Japan's Tax Liability.
(3) The sum of your total amount of income (except for the employment income and the retirement income) and the total amount of earnings from the salary etc. not subject to the year-end adjustment exceeds 200,000 yen when the salary etc. is received from two or more sources and all of the salary, etc. is subject to the Japanese withholding.
*However, you need not file a final return if the remaining amount after subtracting the total amount of deductions for income (except for deductions for casualty losses, medical expenses and donations and basic exemption) from your total amount of earnings from salary etc. is 1,500,000 yen or less as well as your total amount of income (except for the employment income and the retirement income) is 200,000 yen or less when all of the salary etc. is subject to the Japanese withholding.
Don> 'Subject to Japanese Withholding' excludes Foreign derived income which has not been subject to Japanese Withholding. See 5 below
Don> i.e. All of these statements assume Japanese Sourced Income such as Japanese Dividends on Japanese Stock against which
Don> Japanese Taxes have been withheld, as the Tax liability has been fully met through withholding.
Don> Even Japan Sourced Income other than primary employment income against which Japan Taxes has been withheld still needs to be declared
Don> if totaling more than 200,000.
(4) You are employee of foreign diplomatic establishment located in Japan or a domestic worker and the salary etc. is not subject to the Japanese withholding when receiving payment of salary etc.
(5) You receive salaries, etc. abroad.
Don> All Foreign Sourced Income of any kind must be declared, as it has not been subject to Japanese Withholding, IF the Tax Payer
Don> is Permanent Resident for Tax Purposes, and liable for Japan Taxes on Global Income. i.e. in Japan for more than 5 years.
(6) You are a director of a family company or a relative of the director, and receive payments such as interest on loans, rent for a store, office and factory, and charges for the use of machines and tools besides salary etc. from the company concerned.
(7) The withholding of income tax etc. from your employment income was postponed or you received a tax refund, under the provisions of the “Law Relating to Exemptions, Deductions and Deferment of Tax Collection for Disaster Victims.”
Note: Even when you fall under any of the above, you are NOT required to file a final return if the amount of tax calculated based on your total amount of income after subtracting all of your deductions including the basic exemption is EQUAL TO, OR LESS THAN the sum or less of your Credit for Dividends and Special Credit for Loans etc. related to a dwelling (specific additions or improvements, etc.), applied in your year-end adjustment.
Don> i.e. If you enter the Income amounts and then apply the Credit Allowances, the net Taxable value is Zero, then you do Not need to file.
Don> Credit for Dividends is specifically not applicable to Foreign Sourced Dividends. Therefore, the Foreign Sourced Dividends will need
Don> to be reported.
Don> So, the 200,000 figure is only applicable to Japan Sourced Income that has already been subjected to Japanese Tax Withholding at Source.
