Of course Dalamace, the bulbous bow of Yamato/Musashi was absolutely unique. Though the Germans (Bismarck/Tirpitz/Scharnhorst/Gneisenau), the Italians (Roma class) and the Americans (Missouri class etc.) had a so called "pear-shaped" bow or also called "drop shaped" bow (with slight differences per country), which was at least an improvement compared with the old fashioned bow. The Germans developed this bow type already in the 20ies and applied them to the steamers "Bremen" und "Europe". Also the "Taiho" had it, you mentioned it. But the bow of Yamato/Musashi was far ahead of its time as the discoveries of the wrecks revealed.
