Not entirely sure of the first line on the left picture, but something close to

This would likely be a naval stainless steel (anti-rust) blade made in the late 30's by swordsmith Morimichi. I have never seen this exact inscription. I can't find any reference to this company (Nittō). My translation of the first bit could be throwing me off, but for sure this is an anti rust blade from the 1930's.
The poster and site admin named Toritoribe may be able to read the ones that are unreadable to me. If not, you can also post this to the Nihonto Message Board, which is a forum dedicated to Japanese swords (including militaria). There are some people on there would might find this sword very interesting.
