To each their own, but I would caution all of us to paint an accurate picture here rather than a lopsided one as this is after all forum and the thread which those who have not been to Japan will read and possibly use as a basis for their impressions.
You are absolutely correct. My apology for the poor choice of wording. I've edited my original post, so people would be able to get a better picture why stroller-use could be a problematic in train.
Then, off to the topic, things I find it so challenging, especially in Tky.
Lack of Elevator/escalator at some major train stations (even till this day, there are stations without elevator/escalator due to a limited space). When I am carrying heavy/bulky luggage, I don't want to be carrying these up/down the stairs. But, either Elevator is concealed (can't find it!!) or located at faaaaaar end of the platform or super inconvenient location from where you exit the train, it just a pain to locate elevator/escalator.
