Mitsui O.S.K. Lines (MOL) held a special event on Marine Day 2025 (July 21) to mark the 30th anniversary of the holiday, in collaboration with Japan’s Ministry of Land, Infrastructure, Transport and Tourism and the Nippon Foundation. As part of the celebration, MOL hosted a tour of its LNG-fueled car carrier CELESTE ACE for about 600 students and their families. Participants explored the ship's bridge, crew quarters, and watched a live car-loading demo. Additional hands-on activities, including a ship simulator and MOL’s new interactive museum Funeshiru, helped raise awareness about the shipping industry. Around 250 MOL staff facilitated the event. This initiative is part of MOL’s “BLUE ACTION for ALL” campaign, which runs from July 21 to October 9, promoting global social contributions and ocean awareness.
