Why did Japan standardize around the Type 96 25 mm gun?

Why did Japan replace older medium and light anti-aircraft weapons with the Type 96 25 mm gun?

The explanation given here is logistics and infrastructure: the navy chose around what it could supply and support.

No detailed performance comparison is offered. The answer points instead to the logistics and infrastructure available to supply and support the weapon. That shifts the decision from an isolated judgment about gun characteristics to the capacity of the naval system behind it. Supportability is the limit of the explanation given here and does not justify adding weapon specifications.
