About this tour
When Mia from our BugBitten team joined this three-hour experience in Tsuruga, a quiet port town on Japan's Sea of Japan coast, we got a rare peek inside Okui Kaiseido — a 140-year-old kombu (seaweed) specialist that doesn't usually open its aging warehouse to visitors. A guide walked us through how kombu shipped from Hokkaido develops its umami punch in Tsuruga's cool climate, then we watched a craftsman work through a live tasting of different vintages. The day wrapped with fresh sushi lunch using local catch. It's a niche culinary deep-dive, not a standard sightseeing tick.
Highlights
- Access to a rarely-opened kombu aging warehouse normally closed to public
- Live demonstration of traditional Oboro Kombu Suki craftsmanship by a master
- Tasting session comparing kombu aged across different years and their umami depth
- Luxurious sushi lunch featuring the freshest local Tsuruga seafood
- Private executive transfer in a premium Grand Ace vehicle both ways
- English-speaking guide and interpreter included throughout the experience
- Walking through 140+ years of family kombu tradition and historical knowledge
What to expect
Expect a slow-paced, intimate morning that rewards curiosity over tick-box tourism. You'll arrive at Okui Kaiseido and be guided through their warehouse — a bit cool and atmospheric, with stacks of kombu in various states of maturation. The craftsman demo is genuine craft: you'll watch hands-on technique, not a polished performance. Then comes the tasting, where the differences between kombu vintages become clear if you pay attention — it's less about flavour fireworks and more about developing a palate for subtle depth.
The sushi lunch arrives in the afternoon, unpretentious and generous with local fish. Tsuruga itself is a working port town, not a tourist precinct, so the pace feels unhurried. Our team found the interpreter helpful for bridging the gap between the guide's expertise and our questions, though the experience doesn't require deep knowledge going in — the staff explain as you go.

Good to know
This is genuinely exclusive access; most visitors to Tsuruga won't get inside that warehouse. If you're curious about how Japanese foodways work beyond the plate — the provenance, the craft, the time involved — this hits different. Food lovers and people interested in Japanese culinary history will feel like they've learned something real. The private transfer takes hassle out of navigating a smaller town.
The experience is quiet and detail-focused; if you're after excitement or big group energy, it won't deliver. The walk through the warehouse is modest — not strenuous, but you're on your feet for a couple of hours. The sushi lunch excludes alcohol, so drinks cost extra. Tsuruga is a genuine working town, not a polished tourist destination, which we loved but some might find low-key. Peak season could mean booking well ahead.
Comfortable shoes, a notebook if you take notes, patience for slow explanations. Included: sushi lunch, guide, transfers. Not included: drinks, any extras at lunch.
