Info on vintage Japanese Pull Planes/Irons

A couple of months back I found a couple of Japanese wood planes on Craigslist. I couldn’t walk away from them once I seen them. He was a fella up in his years and he stated that his father had brought them home from Japan, during the reconstruction after World War 11. The reason he was selling them was that his grandchildren kept playing with them as a toy. He wanted them to be where they would be looked after.

I have a close friend who’ wife is from Japan, I had here try to tell me what the writing meant. The only things she could tell me is that the characters were from before 1930. and that the blacksmiths mark is a famous one. But she is unfamilar with plane irons, so I still am trying to figure out what I have found.

Any sources of information would be appreciated.

Thanks
