Samurai are proficient with all simple and martial weapons, plus the katana, naginata, and wakizashi.

If Samurai are proficient with all martial weapons, why is the naginata listed as a specific proficiency? As far as i can tell it is a normal martial weapon that doesn't have any special properties like a katana. Was it supposed to be some other exotic weapon like the tetsubo or meteor hammer, or just omitted/ignored?

It was probably originalyl going to be exotic but they changed their minds and this slipped through editing.
