And that's quite surprising to hear. I also live in Tokyo, but given how packed Chuo line/Shinjuku station in the morning for the past few weeks, it feels like everyone has already gone back to their regular office hours routine. :(
Many people from our company prefers working from home as well, so I'm waiting to see how our HR reacts (we already have a 3 days WFH policy in place, but many people now kinda wish they could do permanent). However a large enterprise I'm working with already asked everyone to go back to office, in addition to never issuing WFH for their non-Tokyo office in the first place, which is kinda shame, because I wish they would be adopting with the "new normal", but instead they just go back to normal...
