Can you combine government subsidies with income tax deductions?

Yes. Beyond direct cash subsidies, qualifying green renovations grant an income tax credit equal to 10% of standard construction costs (up to 250,000 JPY tax reduction).

Does property tax decrease following green renovations?

Yes. Filing notification with your local municipality within 3 months of completion entitles the building to a 1/3 fixed asset property tax abatement for the subsequent tax year.
