This saying is one that my informant said she uses on a regular basis:

“No matter how thin the pancake, there are always two sides”.

My informant said that she learned this proverb or saying from a friend that was born and raised in Japan. Her name was Kozuko, and my informant met her in the 1980’s when her husband was stationed in Japan for the army. My informant believes that it was a proverb that was common within Kozuko’s family. Kozuko had translated the phrase from Japanese and told them how to say it in English. My informant thinks that it originally may have been a different word than ‘pancake’, because those are not a Japanese food. My informant uses this saying, she says, to express that there are always two sides to a story. She told her kids this when they would make decisions without considering the consequences or the people that they could hurt in the process. She says that she always thinks of her friend Kozuko when she uses the phrase, and is happy that she was able to bring it back to California.

I, for the most part, agree with my informant’s analysis of this piece of folklore. I believe it was likely developed as a more clever way to say that there are two sides to every story. I believe that this metaphorical way of saying that is a good way to get the message across. I had never heard this saying before, and after researching it more, could not find many sources and sites of it. This leads me to believe it is a rather rare saying, and potentially rarely translated from Japanese, or wherever its true origins lie.
