I am seeing a lot of ARP requests for my router IP from the same IP within seconds.

Get us the MAC address that is asking. This will give us the card manufacturer, which will then, perhaps tell you which system on your network is the culprit.

It looks like it's his router that is asking and the requested device is not responding. Is the "who-has IP" address up and valid?
It would be interesting to know what IP address is being asked for.
For example, this is the router asking, and of course the router's interface is statically configured, and the address it is looking for is either its:
The DNS server The NTP server The SYSLOG server The COPS policy server (yeah, like anyone has implemented COPS and if they did, this would be an anycast)
The SYSLOG server has my bet, as a router, configured for remote syslogging will always have something to send to its syslog...
