When you get Military Tactics you can build both Samurai and Pikemen. The thing is Pikemen can upgrade into Pike & Shot, which has the same strength as Musketmen, is effective against Cavalry units and doesn't require any resources. Whereas Samurai upgrades to Musketman, but needs Niter to get that upgrade.
Plus in my games the AI seems to be fond of deploying Cavalry during wars, so this is another incentive to build Pike & Shots as they are anti-Cavalry. Musketmen don't seem particularly effective against them. (if you have Niter as Japan, otherwise Cavalry take out your Samurai easily)
