Our Wishes
I love the beautiful sea
I want to protect our beautiful ocean.
I want you to feel the blessings of nature with your whole body.
We want our rich lives to not end with consumption, but to be reborn as new value.
We want to reuse the plastic materials used in our daily lives instead of discarding them, and spread eco-friendly sports activities.
Legacy For The Future
Let's start with what we can do
For all those who love the sea. And a small step towards entrusting marine sports to future generations as a cultural heritage.
That is the policy of Save The Surf Project.
Create Together
Turning your ideas into reality
I want to protect the beauty of the ocean.
Your "feelings" that resonate with that wish,
This has taken the form of a transparent surfboard called "Sea Through."
Your steps are our driving force.
And that step will be a wave that creates a sustainable future for the ocean.
From now on too──
Would you like to join us and feel the waves?
Thank you. And let's continue to be together.
