This article explains that how recent academic findings in the relationship between circadian rhythm and light affect lighting in future and what we should do for it in Japan. Firstly, One of features of Japanese lighting environment is high color temperature lighting from evening to night. It is possible that it causes melatonin suppression at night. Secondly, tight energy savings has been demanded since the great east Japan earthquake in 2011 and low light exposure for it possibly leads to poor circadian rhythm. Examination of these two hypotheses and development of color coordination technology to maintain healthy circadian rhythm have to be done in order to compete in global lighting market.
