Do You Know Any Sapporo Or Chitose Pen Stores?

[flexy]

I will be heading up to Sapporo for the weekend and wondering if there are any fountain pen stores. Because Sailor launched a pen called Sapporo it makes google search quite difficult.

 

All I can find is Daimaru Fujii CENTRAL, which looks like a commercial stationary Itoya or Maruzen. I was hoping for fountain pen specific/mom and pop type store.

 

Thank you
