Is this Something One Should Eat?

The hostel where we were staying in Tokyo, which we highly recommend, was not far from the food market, a long, narrow alley packed with neat, clean, attractive stores, some of which sold things to eat, presumably, which we could not identify. In general we found the food in Japan delicious. Even very simple restaurants served well-cooked dishes. However, very few of them had English menus, and, since we avoid certain foods, just pointing at a picture on the menu wasn't so helpful. But the food market gave us a better idea of what people actually bring home and eat.
Here's one of those unhelpful (for us) menus:

Some of the stuff was easy to identify, like snacks:

And dozens of kinds of pickles:

Though it wasn't easy for us to tell just what had been pickled.
Everywhere we went we saw stores displaying sweets that sometimes seemed to be intended more as gifts than as something to be eaten:

There was plenty of street food at the market, like these deep-fried dumplings (which we sampled):

And some mysterious things:

There was plenty of seafood:

And they love tiny fish:

As for noodles, there was an infinite choice:

A fine take-out delicatessen:

And even ordinary fruits and vegetables were displayed like crown jewels:

So, if you get to Kyoto, don't miss the market!
