I thought all Asians used the knuckle method, although that seems potentially bad with a round bottomed pot.

I have a pot similar to what you posted, but larger that my parents bought or won as a door prize when we lived in Japan. I didn't know it was for cooking rice. I thought it was for some sort of one pot meal with a bunch of stuff in a broth.

The first time that we lived in Japan, I was in the 2nd, 3rd, and 4th grade. One year in school, we had a Japanese cooking thing where a lady came in and "taught" us how to make chicken fried rice. She brought a rice cooker and used the finger/knuckle measurement method, but I never could remember what that was. Of course, it's all over the Internet now.
