I just got back from a trip to Japan and I brought my Sigma 35mm f/1.4 Art and Canon 24-105mm f/4 L with me. Ended up shooting the entire trip with just the 35 and left the 24-105 at my Airbnb. There were some cases where I wish I had the reach or a bit of a wider lens but overall, I really enjoyed shooting with the 35. I think everyone else nailed it on their recommendation of bringing the 35 and 85.
I'm still editing pics but here are some shots:
