As a step of the National Innovation System, foresight activity is increasingly operated in a variety of countries. One of the major methods in the foresight studies, Horizon Scanning method is being penetrated in the world foresight community. We investigated such national foresight activities in Taiwan, Thailand, Philippines, South Korea, Iran, Singapore, Brunei, Australia, China, Finland, and USA. On the other hand, we found that in Japan, corporate foresight activities are more active than Japan’s national foresight activity. In about 15 years, many Japanese corporates have adopted Horizon Scanning method as a way of idea generation for new business developments. However recently, some Japanese corporates refocused on the same method as a way of building internal inno- vation ecosystems, in which creating their own future chronology map was effective to share common future scenarios in their organizations. In Japan, sharing common future scenarios between national and corporate level should be a current challenge.
