Jyankare! (Curry question)


My family and I visited Yokohama and ate a place called Jyankare. It was so good, we found ourselves there 4 times during our trip to have the spicy beef curry. I have been dreaming about this curry since being home for 4 months, but I’m not sure exactly what it is. Upon research, it seems like it may be Kuro Curry. I wanted to ask if anyone knows what kind of curry this could be and what I would need to get to make the base at home. Thank you!
