Trying to locate that and its followup Kyokujitsu no Kantai, from 1993 and 1997 respectively.
There´s supposed to be a subbed version of it from somewhere, i´ve even found a few dead links for torrents with the subbed version though never including who did the subbing, but its totally impossible to find a working link it seems.
From descriptions i have found it seems to be a rather interesting alternate history story, basically when Isoroku Yamamoto gets killed, he suddenly finds himself quite alive again but in 1905, and goes on to change history together with another "throwback" he finds. With one country getting 35 years worth of preparing for WWII, with knowledge of developments in those same years, things goes very differently...
I expect anyone who liked "The final countdown" or "Zipang" and alike might want to see it...
