Reviews Summary

Visitors find the OTEC Kumejima Deep Sea Water Research Center to be an impressive and forward-thinking facility, particularly appreciating its role in sustainable energy research and the unique applications of deep sea water. The industrial architecture is noted as a striking visual element. Some visitors may find the experience more educational than overtly entertaining, and advance booking is essential.

"It's a cool building.
Asahaka is the one wondering which is more important: pumping electricity or generating electricity?! Deep sea water itself has value in that it is sterile, so I imagine this is an experiment to try generating electricity at the same time.
As you're driving along happily, an impressive industrial structure suddenly appears.
Kumejima uses deep sea water for sterile oyster farming, and it seems that there are even greater expectations for its use in the future."
