[Desertfox]

Very similar to the OTL version. This class has an improved armament with new 45 cal 12" guns, 2 knots faster than the Fujis, and an improved armor that allows reduction in thickness. Four were built (Shikishima, Hatsuse Asahi, Mikasa), two to the slightly improved Mikasa design. Mikasa herself has expanded flagship facilities.

Twin casement mounts?
These appear to be at freeboard deck level, in which case they have the 7" face shield, but are not protected by the upperbelt armor.

      14 - 6.00" / 152 mm 45.0 cal guns - 108.92lbs / 49.41kg shells, 150 per gun

Your 1899 6" guns can be quickfire if you like.
otherwise same comment.

Hey single casements !...also can be QF and currently on deck completely unshielded

From the pictures, all are supposed to be 'below deck'.

[Kaiser Kirk]

For my purposes, unless otherwise specified,
I figure the upper belt starts at freeboard, and covers down.
Then the main belt starts.

So for Fuji, that's
4.27
1.83
-0.61

That's actually reasonable for that period.

For Katori,
4.57
2.13
-0.92

Still ok for the period.

But Shikishima
4.57
2.13
0.31

That's a bit shallow. Somewhere in the 0.5 - 1.5 range would be about right for the period.
While diving shell wasn't even a consideration, from a practical point of view, at normal load, the wave period might expose the underhull,
and it would take very little roll to expose it occaisionally.

[Desertfox]

Those should be single mounts. I do need to fiddle around with the secondaries and extend the belt height on the Shikishima.

[Desertfox]

Battlecruiser versions of the Katori class, dropping the heavy secondary and some armor for more speed, similar to OTL but significantly faster. They are designed to fight on the battleline if needed. Two built, Tsukuba, Ikoma.

Image only to provide a rough idea of how they look, the secondary layout and freeboard are different than depicted.

That should be all of the capital ships. Ten battleships and four battlecruisers. Cruisers are next, eight in four very similar classes.

Unsurprisingly, the Tsukubas ended up being remarkably similar to my old New Switzerland Constitution class.
