Thank you for your continued support of MSO.
This Saturday, September 5th, 2026, we are thrilled to host the “4th MSO Marine Leisure Festa Produced by NosTech”. As our final summer event of the year, this festival is themed around providing the “Ultimate Chill & Thrill for Adults.”
We have received a massive response, and there are now ONLY 9 slots remaining (4 Men, 5 Women). Registration will close immediately once these spots are filled, so please hurry if you are considering joining!
Bringing Marine Leisure to Everyday Life
As highlighted on our website’s homepage, MSO’s concept is to provide “Enjoy Marine Fun at Everyday Prices.”
For this festival, we have scaled up this vision. Enjoy 6 hours of unlimited rides on thrilling marine sports, including jet skis, towing tubes, and banana boats! After experiencing the exhilarating rush of speeding across the beautiful blue ocean, relax and chill out with our all-you-can-eat BBQ and a premium music space curated by our live DJ against the backdrop of a spectacular ocean view.
An Unbelievable “Loss-Making” Price
Normally, an experience of this scale would cost over ¥50,000 per person. However, because this is a special passion project produced by the marketing firm NosTech, we have drastically reduced the adult price.
Including the BBQ and all-you-can-drink soft drinks (which typically cost around ¥4,000 alone), we are offering this at the unbelievable price of ¥7,000 per adult! This means you get 6 hours of unlimited marine sports for essentially around ¥3,000—a one-time-only pricing miracle.
