Based on what I've learned over the years, these razors (or something similar) were original to China and were brought over to Japan thousands of years ago. I'm not sure of what the Chinese style looked like but the Japanese style predates the Western style. Initially used by monks on each other, they were then used by barbers on clients, and finally, people used them on themselves. They're not used much at all in Japan nowadays.
Traditionally, kamisoris are different from Western razors in how you hone them and how you use them. They're used with one specific side against the face at all times. The side with stamps is called the ura. The side without stamps is called the omote. You're supposed to shave with the omote against your face - never with the ura against your face. When these razors were used by barbers on clients, that was easy to follow. When you're shaving yourself, it's much harder but still doable. When you hone a Western razor, you hone in a 1:1 ratio. Each side gets the same amount of passes as the other. The kamisori method is to hone the omote more than the ura. Instead of going by feel, most people use an unbalanced ratio of something like 10:3 or 10:1, omote to ura. Some people go 30:1 or don't even hone the ura side at all.
I follow the traditional honing method so I can preserve the asymmetrical shape of the blade. However, I use both sides of the razor. Forcing myself to use just the omote is unnecessarily more work than I'm willing to do for a shave. Of course, you can do whatever you want. Ultimately, the goal for most people is just a great shave and if honed and used properly, you will certainly get that.
