Storage temperature - Nihonto & Koshirae

[FZ1]

I've used the Search facility and got loads of info about humidity levels, but this one is about temperature.

 

Is there an optimum temperature to store blades and/or koshirae?  Is there a minimum recommended temp?

 

Thanks.

The site below says 22 degrees celsius (71.6 F) is the optimum temperature for swords with lacquer koshirae. Actually it says this is the temperature at which museums keep their swords (no other details on how they determined this).
