About this tour
Step into Nachi-Katsuura's working tuna auction, where Japan's finest catch arrives daily. This guided tour walks you through the port's grading process, revealing how buyers assess quality and the mechanics of the sale floor. You'll learn why long-line fishing keeps these waters sustainable and meet the tight-knit community—fishermen don't even live here—who've built their livelihoods around this single-species economy. Ninety minutes of genuine harbour work, not theatre.
Highlights
- Watch buyers grade tuna by eye and touch in real time
- Understand long-line fishing's low-impact ocean practices
- Hear why "never frozen" actually matters to taste

- See Japan's premier tuna landing port in operation
- Walk the auction floor with a local guide
What to expect
You'll move through the active auction market at ground level, observing graders and buyers at work. Expect noise, cold temperatures, and wet floors—this is a functioning port, not a museum. Your guide explains the assessment criteria in real time: colour, firmness, fat marbling. You'll learn the counter-intuitive fact that tuna fishermen don't settle in this town, then discover which other professions anchor the local economy. The tour moves at a steady pace but suits all fitness levels. If you time it right, your guide can point you towards a local spot for fresh tuna breakfast afterwards—your shout.
Good to know
Tours run early, so wear layers and closed shoes. The market is a working space; expect wet floors and cold storage areas. Public transport connects nearby if you're not walking from accommodation. Prams and strollers are fine. Guides can recommend restaurants but meals aren't included.
