“Is there anything to do here?”
If you're in Tokyo for a holiday, you're looking for fun right? You want to experience Japanese culture right? Kanda has very little of either of these things.
Do you know anyone who says amazing things about Kanda? Probably not.
Upon exiting the JR station you will greeted with pretty much nothing that cannot be found outside or around any JR station. I have wandered the area looking for some semblance of fun, but have yet to find it. Perhaps maybe I need to wander further, though perhaps there are just more exciting places in Tokyo to be explored.
Kanda is not awful by any means. Be I have found nothing enjoyable here.
The station is alright though.

In the Edokko neighborhood of Kanda, you can also take a historical stroll as well as do some specialty shopping.
