Yokohama Hakkeijima SeaParadise will be hosting the "Wakame Harvest Experience" event from March 1 (Sunday) to March 31 (Tuesday), 2026. This unique event allows visitors to learn about, harvest, and eat wakame seaweed, which is in season during spring.
As interest in environmental issues grows, Yokohama Hakkeijima SeaParadise has been planting, cultivating, and harvesting wakame seaweed, which absorbs carbon dioxide through photosynthesis, as part of their efforts to raise awareness about global warming and ocean environmental issues.
This event provides visitors with an opportunity to experience wakame harvesting firsthand at Umifarm, the natural ocean aquarium, while learning more about this marine plant. Participants will also learn about the important role wakame plays in the ecosystem, the significance of blue carbon, and environmental issues surrounding the ocean. After the experience, visitors can take home the wakame they harvested and enjoy it at home.
Yokohama Hakkeijima SeaParadise, under its corporate slogan "Bringing smiles and excitement to the world through living creatures," aims to provide all visitors with opportunities for smiles, excitement, and learning experiences while fostering interest in marine life, their ecology, and the ocean environment.
Wakame Harvest Experience: Learn, Harvest, and Taste Spring's Seasonal Seaweed
At Umifarm, the natural ocean aquarium, visitors can participate in the wakame harvest experience, harvesting seaweed that was planted last December and has grown large. As concern for environmental issues increases, this facility has been planting, cultivating, and harvesting wakame, which absorbs carbon dioxide through photosynthesis, as part of efforts to promote awareness about global warming and ocean environmental issues.
This event offers visitors a chance to experience wakame harvesting while learning more about this seaweed. Participants will also receive explanations about the important role wakame plays, the significance of blue carbon, and the environment surrounding the ocean, helping them learn about global warming countermeasures and ocean environmental issues. After the harvest experience, participants will be served wakame rice. Additionally, visitors can take home the wakame they harvested to enjoy at home.

About Blue Carbon
Blue carbon refers to carbon dioxide and other carbon absorbed and stored by marine organisms such as seaweeds and seagrasses. Just as forests absorb carbon dioxide through photosynthesis (green carbon), marine organisms also play a role in reducing greenhouse gases and mitigating global warming. At Yokohama Hakkeijima SeaParadise's Umifarm aquarium, visitors can experience planting and harvesting wakame seedlings while learning about the importance of blue carbon and raising environmental awareness.
