Japan is experiencing the highest aging rate in the world and cannot be expected to manage the sharp increase in GDP due to the population decline. Innovation is necessary to increase GDP in the age of population decline and allocate not only human resources but also physical resources from the centralized Tokyo area to local areas, which is called ‘regional revitalization’. Development of the tourism industry, agriculture and fishery is necessary for regional revitalization. Japan’s hospitality in the tourism industry is said to be the best in the world, however the cost is low and an improvement of labor productivity is expected. It is essential to be able to attract innovation which utilizes artificial intelligence and IoT (Internet of Things). It is also important to fit the thoughts of SDGs and Society 5.0.
