A single 46cm (18.1 inch) 45 cal. naval gun from the Yamato-class weighs a 162.4 tons with a firing range of 45,960 yards compared to Yuugumo-class 12.7 (5 inch) 50 cal. 3rd Year Type Naval gun which weigh 4.18 tons and has a firing range of 20,100 yards.
Of course, Yamato's triple-gun turret weighs 2,774 tons which exceeded the maximum displacement of a destroyer (the Yuugumo-class battle displacement is 2,520 tons).

Ummm... The 41 cm cannon was on the Nagato-class. The Yamato-class had a 46 cm cannon that weighed 147 tons.
Anyway, this strip shows the general reason why Japanese battleships tended to be useless at the "long distance sniping" role they were designed to take for reasons already explained.
They were trying to hit targets hypothetically as far as 46km away, but their actual effective range was half that, at best. Simply put, it was impossible to actually accurately hit a target when they were relying upon optical range-finding and manual targeting calculations. By the time they were done playing "telephone" relaying the guesswork of how far and fast the enemy ships were going, and the math nerds in the calculation room were done calculating, the turrets had been aimed, the shells fired, and the shells actually traveled the 40 km (through wind conditions completely unknown to the people in the calculation room), then even if most of the math being plugged into the calculations weren't rounded-off guesswork, and they actually could have hit where the ship was going, it had already taken a couple minutes between the sighting and the actual shell landing. As with the Battle Off Samar, a destroyer could simply turn, and evade everything the battleships could try to dish out.
What Musashi is saying is something like a sniper's way to shot a target.
Because it is.
Snipers simply don't get that in-depth because sniper rifles can't hit targets outside the range of 10km (yet?), at which point you DO need to start including things like the Earth's curvature.
If you want to handle 46cm gunsHi! Today is Kiyoshimo’s turn! Today, Yamato-neesama and Musashi will be giving special training to become a battleship!Aw right!!You also need to study for it...What is this person talking about ?Yamato, hold it steadyHow should I fire this ?This is very heavy!Eek eekOoh! And suddenly I’ll get the chance to fire the main guns!?Hmm… first you calculate the enemy position and direction as well as wind speed, direction, temperature and moistureBuuurning Loove!What?What?What?Also consider the earth’s curvature and change in gravitation then correct the numbers to it.
Don't forget that the Earth's rate of rotation in distance changes with latitude
