Work you can ask us about
For the Advanced Window Renovation 2026 Programme (先進的窓リノベ2026事業), reservation applications close on 16 November 2026, or earlier if the budget limit is reached. Regular grant applications remain open until the budget limit is reached, and no later than 31 December 2026.
Reservation and regular application deadlines differ. Products, pre-work photographs and project progress must be checked; neither a grant nor meeting the deadline is guaranteed.
What we tell you first
- We will review the next programme after its terms are published. Privately funded insulation consultations are also welcome.
- We will build our portfolio and official Instagram archive using project photographs and records cleared for publication.
