No, sesame oil and soy sauce are not the same. They could not be more different. Sesame oil is the result of pressing sesame seeds until oil is extracted from them. Sometimes the seeds are toasted beforehand to give a slightly different flavor to the oil. The resulting liquid is a smooth, fragrant oil that smells nutty and subtle with a sweet, nutty taste. It is an important component in many dishes, particularly from Asian cuisine, and can be used to cook with or even as a dressing.
Soy sauce, on the other hand, is a liquid made from the fermentation of soybeans. It is a dark, very thin liquid with a water-like substance rather than oil. The taste is the very definition of umami as it is salty, sweet, sour, and savory all at the same time. It is also a very important component of Asian cuisine, which could account for why people get it confused with sesame oil since both are important ingredients in many of the same dishes.
