The three grand soups of the world (世界三大スープ sekai sandai sūpu) is a common term in Japan referring to three types of soup thought to be the best in the world.
[1][2][3] The origin of this term is unknown, though it was already in use by the 1980s.
[4] Notwithstanding the term, there are four soups referred to as "three grand soups."
This is because borscht and tom yam kung are considered to be tied for 3rd place.
