I live in Japan and have done this last year to great effect. My work place is about an hour and a half commute and the trains are incredibly packed starting from around 7am all the way till 9.15am. What I've done was wake up and started working from home sometime between 7-8am till around 9.15am, then leave for the 9.30am train and I'll be in the office by 11. Work gets done and I don't get stressed from silly crowds. I also do the reverse and leave work around 4pm to avoid the return rush. It's a small change but it's an incredible quality of live improvement. This is literal pareto, 20% effort with 80% effect. Do it.
