Alternatively, you could perhaps, y'know, learn Japanese.
Depending on how desperate you are, the real cheap way of playing this game in English would be to set up something that takes screen captures, runs OCR on them (one way or another), feeds the result into a translator, and spits the English translation out in another window. I think there was an early doodad written for Mother 3 that did something similar.
By the way, you're aware there are a whole bunch of other versions of Itadaki Street aside from the SNES one, right?
