When should I arrange an independent inspection for an Osaka new build?

Cash will be tight around handover because moving, furniture, service charges and the first mortgage payment all arrive close together. We are looking at a 3-bed new-build flat in Osaka, so I am trying to choose one useful inspection point rather than pay for checks that duplicate each other.

The developer considers the municipal approval sufficient. I am less convinced, because a buyer’s inspector may be looking for drainage problems, weak insulation performance and poor finishes that a general compliance check does not settle.

Would the best use of the money be an inspection shortly before handover, when faults can still be recorded before moving in, or a later visit while defects can still be raised? I also need to know what can actually be tested if the utilities are not yet operating.

I would not treat the municipal checks and an inspection commissioned by the buyer as interchangeable. If access is allowed, the most useful timing is shortly before handover, while findings can still be recorded and raised before you move furniture in. You could then reserve a smaller follow-up for near the end of the defect period rather than paying for two full inspections.

Before choosing the timing, ask what the inspector can actually examine. Will water and power be operating? Can they test drainage, or only look at visible finishes? How would they assess insulation or energy performance in a completed flat? Also read the contract for the defect-notification process and access arrangements. A broad inspection sounds reassuring, but a vague scope may not answer Emma’s main concerns.

I would push back slightly on spending heavily just because it is a new build. Protecting the emergency fund matters too, especially with moving costs, service charges, an insurance excess and the first mortgage payment arriving close together. Get a written scope and price first, prioritise moisture, drainage and defects that will be hidden by furniture, and keep dated photos of every finding. Leave cosmetic purchases until after handover so there is room in the budget for any immediate repairs or follow-up inspection.
