Napping at work has been a part of Japanese culture for centuries and is becoming increasingly popular in the corporate world. There are numerous benefits to taking a nap during the day, including improved concentration, increased productivity, and better overall health. In Japan today, there are several different types of nap time practices that employers can implement into their own workplace environment. These include "Matsuri", "Inemuri", "Shukudai", "Jishuku", "Gakari", "Oyasumi", and "Kaisu". Employers need to consider certain challenges when introducing nap times such as resistance from management/colleagues, potential losses due reduced productivity, and risk assessment & safety considerations.
