The Tardis..

(above) A Japanese Elementary School child waits for the train that will take him back in time to Prussia.

In the 1800's Japan looked at all the educational systems in the whole, wide world and decided that that the Prussian educational system was best.

I suppose it wasn't such a bad choice when you consider that the whole world wasn't so wide back then and Prussia was relatively close geographically speaking.
Besides, how many different educational systems were there to choose from in the 1800's？

My question is this:

200 years have passed. How about a change of uniform？

Whenever I see uniforms like this I expect see a parade of mounted soldiers with well-waxed mustaches, sabres bared and medals glinting in the sun shortly thereafter.
