Shogun 2: What am I missing?

So I'm playing a vanilla shogun 2 campaign as the Chosokabe. I want to recruit some Daikyu Samurai.

I have the necessary buildings and technologies, yet I have no option to recruit them. Can anyone take a look and see if I'm missing anything?

According to the ig encyclopedia I should only need an archery dojo and a hunting lodge, both of which I built.
