Nobody doubts Japanese people's great love for curries. They reinvent curries in different shapes and patterns, and "soup curry" is one of them. 

According to Wikipedia, the term "soup curry (スープカレー)" in Japanese indicates a "curry (or masala) flavoured soup (stock)," invented in a small restaurant in Sapporo, Hokkaido, in the 1970s. Today I encountered one of such "Sapporo-born" soup curry restaurants at TORIUS Hisayama shopping complex, Fukuoka, on our way to Costco Wholesale. 

SAMA is, without exception, from Sapporo. 

Mother ordered "Grilled Chicken with Assari [simple] soup.
Assari soup is very similar to shorba (soup) in India,
with a lot of dhania (coriander) and jeera (cumin) use.

The menu.
