The situation was different. Firstly, Japanese Navy was already non-standartized, with numerous ships of different origin and designs. If anything, addition of Russian prizes increased Japanese uniformity (since those ships were mostly build for same standards)
Secondly, this measure was heavily criticized even then, as waste of resources that could be much better implemented to build new warships. The restoration of Russian prizes - especially heavily damaged ones - took a massive amount of money, and did not actually provide IJN with any kind of lasting combat capability, since with a few exceptions ("Oryol" and "Retvisan") most of the prizes were of 1890s build.
If anything, the great cost of restoring the prizes damaged Japanese entry into dreadnough era; they were forced to abandon the idea of completing the Satsuma-class battleships in all-big-gun configurafion due to lack of money for more 12-inch barrels.
French and Germans used metric system.
Again; France, Italy and USSR were all-metric, so supporting those ships wasn't as big headache. Also, French Navy was pretty much as mishmash of French, British and Ameican warships already, so they simply don't care.
