Sanriku Geopark Fishing Industry Field Trip: Explore Otsuchi Bay's Working Waters
Step onto a local fishing boat in Otsuchi Bay and watch centuries-old aquaculture and set-net fishing at work. This guided field trip explains how scallops, oysters and seaweed are farmed on Sanriku’s rias coastline and why seasons and tides shape the harvest.
The Experience
Before You Go
Dress for spray and wind
Bring a windproof, water-resistant layer and non-slip shoes—the bay can be cooler and wetter than shore conditions suggest.
Bring binoculars
Birds and distant farm lines are easier to study with optics; a small pair highlights seabirds and raft layouts.
Mind the boarding
You must be able to board independently and follow crew instructions—no wheelchair access is available.
Respect biosecurity
Do not touch farm gear or consume samples; biosecurity and safety rules protect farms and guests.
Local Knowledge
Hidden Gems
- •Early-morning visits to the local fish market in Otsuchi where boats land fresh catch (check market hours)
- •Short coastal walks near small headlands for elevated views of raft farms and rias geometry
Wildlife
- •Black-tailed gulls and other seabirds
- •Occasional dolphins or porpoises offshore
Conservation Note
Local operators emphasize sustainable aquaculture practices and strict biosecurity—stay on the boat and follow guidance to avoid disturbing gear or spreading marine pests.
Sanriku’s set-net and raft aquaculture trace back centuries and adapted to the rias coastline; communities rebuilt fishing infrastructure after the 2011 Tōhoku tsunami, blending tradition with modern safety.
