If there happen to be any readers of Japanese in the audience, or anyone more familiar with Japanese cuisine, perhaps they could tell me what this is:

I had it in the train station in Kamakura yesterday (albeit with udon rather than soba). It was pretty tasty, but I have no idea what that hash-brown-like thing was. It had a sort of doughy texture inside. It might have been tofu, but it didn’t really seem like tofu.
Hmmm. Ko-ro-tsu-ke with either soba (as pictured) or udon. But, I don’t know what Ko-ro-tsu-ke is.
“Corroke” mixture of potato and ground beef or pork. Mostly potato.
@Jeff: Like “croquette?” Is the “tsu” silent, or modifying the “ro”? It’s been too long since I took Japanese…
This was according to Japanese co-worker. Yes it sounded like “croquette”
