Revised one of the bubble. Please correct it if there's any mistake :)
Since 1869, the predecessor of the IJN Naval Academy is located in Tsukiji, Tokyo (same neighbourhood as the fish market).
Then on 1888, the naval academy is moved to Etajima. This seems to be the model of KanColle anime's base and currently a school for naval officer and technical school for various on board skills (except machinery, that's in Yokosuka).
Have some tea.Say hi to the peeps for me.I'll draw it even better!The fact he drew it so perfectly freehand makes me even more furious...The Naval Academy!? What are you thinking?Well well, send him a fairy from THE Naval Academy.AckHe makes a fool out of the admiral...Looks like shit.He's nosy, and he even scribbled on the map I drew.Ootsu Naval University = Naval Correctional Facility (located in Ootsu, east of Yokosuka)
The real Naval Academy was located at Tsukiji, Tokyo, and was moved to Meguro since 1932Send him a Ootsu Naval University graduate.Whatever, I'm still higher ranking than you.They're supposedly low on personnel.I hate that man.Hey hey, you were promoted?Yeah...You were angry? I couldn't read his facial gestures because of his face.What's this map routing?*SLAP*Wai-The prisoners still had to serve the remainder of their time in military service after their time in jail was over.
By the way, there was actually a map meddling incident done by a certain admiral who graduated second on the list at the (real) naval academy. The Salutatorian ship captain drew over the chief navigator's ship route without hesitation. Furthermore, drew the routing better than the chief navigator without using any guidelines. Ingenious indeed.
