3 nights in Tokyo with an active senior

I’m taking my Mom to Tokyo for 3 nights. She’s 80 and very active. We’re staying at the Shangri La as I wanted to stay somewhere where we can walk or take the subway easily, I haven’t been back to Japan for 15 years, so excited to explore. We’ll be coming from Seoul, so we’ll be doing all of our spa/skincare work there. And we might be shopped out.

Recommendations on what to do?
- She loves golf and golfing (I do not)
- She likes shopping and getting well crafted bargains
- I love fashion and streetwear - any must-visits that are better than what I have in NYC
- Good comfort food - want to avoid anything that is TikTok famous
- Real sumo matches? Arty, designy things?

Grateful for any favorite things or general tips!
