It's on the ground floor in Sogo and you can't miss it as it's near the entrance.
Because it was a high brand's shop, I thought I might feel hesitation to go in but the entrance was wide and there were no security guards who were there before. So I went to look their items just like going in while waiting for the traffic lights.
The staff served me nicely even after the purchase and this shop became easier to pop in than the Kobe main branch.
