Downtown: pick one of three
One Tanukikoji arcade stretch; Mitsukoshi or Marui. Esta / Stellar / Daimaru are transfer supplies — not the spine. Snow days: Chi-Ka-Ho, Pole, Aurora underground.
Day-trip shopping another day
Otaru Sakaimachi glass and music boxes — not a Tanukikoji extension. Chitose Outlet only around flights — not an Otaru day. Factory is rain backup — not plus Outlet Lock the axis before you add another district.
