The ocean energy field is gaining more and more attention as a means towards achieving carbon neutrality, with offshore wind energy being a leading example. In order to efficiently make advances in ocean development going forward, we would need underwater IoT (visual control) to give us a clear understanding of undersea conditions. It is therefore essential that we have the equipment for high-speed wireless communications underwater. This article introduces the technology for visible light wireless communications that my company has been developing for this purpose.

In May 2014, one of the Japanese cormorant of the Uji River laid its eggs there. In the history of cormorant fishing in Japan - said to stretch back over 1,300 years - this was an extremely unusual event. Spurred on by this development, the cormorant fishermen continued their near-annual captive breeding program, resulting in the hatching to date of 17 chicks. Notably, almost no studies had been conducted to that point about the reproductive ecology of Japanese cormorant, so a joint research project was launched to better understand this. After five years of ongoing study, we have come to know much more about the various aspects of the reproductive ecology of Japanese cormorant, including their egg laying and growth process.

On April 8, 2022, the revised Museum Act was passed and approved in the plenary session of the House of Councillors, and discussions are being held regarding the informatization of museums before it is put into effect on April 1, 2023. With the announcement of the GIGA School Program on December 2019 and the surge of online interactions from the coinciding COVID-19 pandemic, we are also expecting greater digitalization of museum activities. Thus, in this article I would like to discuss the state of ocean education digitalization in museums, including aquariums.
