About Sea Japan - Biggest Maritime Event in Japan


Since 1994, Sea Japan has been held under various themes that match the trends of the time and industry needs. Sea Japan 2024, its 15th edition will focus on clean energy and explore the various options for the industry.

The next challenge for the maritime industry is to decide upon the new energy sources that will allow the carbon neutral operation of vessels. Which of the clean energy sources, such as hydrogen, ammonia, liquefied natural gas (LNG), and electricity, will prove to be the right choice for the industry in the future? How will we work to improve efficiency and ensure safety for practical use in the future? Sea Japan 2024 will put this challenge in the spotlight.

A new addition to Sea Japan 2024 will be an offshore and port technology exhibition, “Offshore & Port Tech 2024” as its parallel event. The new event will provide a platform for technology and information exchange between new ocean businesses and the maritime industry, such as the blue economy, the development of marine renewable energy such as offshore wind power generation, and efforts for carbon-neutral ports which are becoming more active recently.

Sea Japan 2024 will create new business opportunities for industry professionals by offering an international network, gathering the latest technologies and information from the world, and continuing to address the industry’s challenges such as environmental protection, digital transformation and human resource development.
