Akiko Yokohama, who works at Spelldata, a small Tokyo-based technology company that allows employees to work a four-day schedule, takes Wednesdays off along with Saturdays and Sundays. The extra day off will enable her to get her hair done, attend other appointments or go shopping. "It's hard to keep going for five days when you aren't feeling well. The rest allows you to recover or go see the doctor. Emotionally, it's less stressful," Yokohama said. Her real estate broker's husband also gets Wednesdays off but works weekends, which is common in his industry. Yokohama said it allows the couple to go on midweek family outings with their elementary-school-age child. Fast Retailing Co., the Japanese company that owns Uniqlo, Theory, J Brand and other clothing brands, pharmaceutical company Shionogi & Co., and electronics companies Ricoh Co. and Hitachi also began offering a four-day workweek in recent years.
