Saitama being dasai is one of the most insane stereotypes out there.
In Kanto alone I can think of at least 3 prefectures more dasai.
Many beautiful people come from there.

This is true. But did it never occur to you to wonder why they didn’t stay there?

This is meaningless dribble. There are escalators and pedestrian walkways where one is to walk on the left and plenty where one is suddenly asked to walk on the right in this country, clearly they lack a plan. Typical Japanese hyper organized inefficiency. Roppongi station is evidence alone. Several walkways cordoned off to walk on the left and several opposite. Makes zero sense. Welcome to Japan. We just stop asking why.

My guess is pedestrian flow design in stations is prioritizing smooth flow during rush hour by avoiding opposing foot traffic from having to cross in tight spaces. That's probably more important than having always-walk-on-left (or right) consistency.

I suspect that pedestrians tend to follow the same conventions as vehicle traffic at the location: right vs left hand drive and where the passing lane is located (left vs right). If traffic drives on the right side of the road, pedestrians on sidewalks naturally keep to their right, while on moving walkways, one would stand on the right and walk (pass) on the left, etc.

In one part of my station there are big signs and arrows saying "stay right" because it's better for the transfer between the two lines. But in practice some people end up walking on the left out of habit, and there are shops on one side so other people slow down or stop there, so it's kind of a mess.


Also, I've been seeing these signs recently in many stations across different companies ( 止まろう is the imperative form of 'stop'). Nobody seems to be paying attention to them.

Exit 3 of Gaienmae station has this approach, where you are asked to walk on the right for traffic flow. Half the people follow it and half don't, so in the end is worse than if they just kept to the "traditional" direction flow. A bugbear for Mrs. Pickles, only second to morons who ride their bike on the sidewalk as if it were completely empty.
