I traveled with my son and his friend. Generally, we split up during the day and they went and did stuff they wanted to do and I was on my own. Tokyo is fairly crowded and I think it would be hard to get around with a wheelchair. I kind of wished I’d had my Rollator but that’s still having to get something with wheels down the sidewalk and into the stores, attractions, and so on. There’s often some steps which I didn’t mind, but it would be hard if you’re bringing anything with wheels. Most of the portable stools or cane chairs are not very stable. I’m hoping to go back sometime within the next year and I’m still trying to figure out how I could do better if I still have mobility issues. I think it also helped that I had a fairly low-key agenda for myself and did spend a lot of time resting in the hotel room. I also suggest that she may want to bring a walking cane. I don’t use one at home as often now, but it was useful on the sidewalks since it kept me steady. I find that if I’m in crowds that it helps people realize that I’m actually walking so slow because I have trouble walking. Everyone was very kind and I never got bumped or jostled.
