The climatic limit on wooden military aircraft

What limits wooden aircraft, and would they be especially useful to a country such as Japan?

They can be effective and save metal, but their glues and laminates must withstand hot climates without coming apart.

Wood was not an inherently crippling aircraft material. A country with the necessary craft skills could produce effective wooden airframes and conserve strategic metals. The main limitation lay in the adhesives and laminated structures that held the aircraft together. Hot conditions could weaken those bonds or separate the material, making climate and glue chemistry central to whether the approach suited Japan.
