Tour — Field Visit & Experience
Learn, experience, taste, and watch — a visit program at the seaweed restoration site
In Kushiura, Karatsu, a sea turned white by isoyake was brought back to a seaweed forest over 25 years. Our visit program lets you experience that work with all five senses — through to the food the sea provides. From corporate training to government visits and press tours, we tailor each program to your purpose. From carbon neutral to nature positive — why not think about your next step with the sea right in front of you?
A talk by founder Shozo Kesamaru: the mechanism of isoyake, blue carbon, and 25 years of practice — in the words of the field, not a textbook.
Depending on the season, observe or join seaweed-bed work and urchin removal. Take home the feeling of restoration in your own hands.
Tasting of wild sea urchin raised in the restored sea, or a seafood BBQ. Tasting the sea is another way of knowing it.
By boat to the restoration site. Compare the revived seaweed forest with barren grounds — the problem and the hope, visible at once.
* Underwater dives to inspect the seabed require extensive preparation and costs for maritime safety.

Most visits fall within 100 kg of CO₂; for long-distance travel or large groups, we may discuss an additional arrangement.
Yes. Depending on whether you free-dive or scuba-dive, the group size, and the equipment involved, we arrange boats, gear, and support staff as required for maritime safety.
We can also provide underwater footage we have recorded in the past.
Like plants on land, the seabed changes with the seasons — the underwater scenery is usually at its best from May to June.
Yes. Working with partner travel agencies, restaurants, and hotels, we can design overnight packages and tours that include visits to partner sites.
