Snow crab season on the Sea of Japan runs from November 6 to March 20, and the Tango Peninsula in northern Kyoto Prefecture is home to one of Japan’s most exclusive crab brands: Taiza-gani. For Japanese travelers, the rules around this are common knowledge. For foreign visitors, the tagging system, the pricing, and the dining format are all unfamiliar territory, and most English-language guides skip the detail entirely.
Asobi Lodge sits in Amino, Kyotango, within the same city as Taiza Fishing Port, where the region’s most exclusive crabs are landed. Hamish and Nora, who run the property, field crab-season questions from guests throughout the winter, which is exactly why this guide exists.
What is Matsuba-gani?
Matsuba-gani (松葉ガニ) is the regional San’in name for the adult male snow crab, Chionoecetes opilio, caught along the coast of Tottori, Shimane, Hyogo, and Kyoto prefectures. The same species carries different brand names depending on where it’s landed:
- Echizen-gani in Fukui
- Kano-gani in Ishikawa
- Taiza-gani in Kyotango
The naming distinction matters in Japanese food culture, where landing port is treated as a genuine marker of quality, not just marketing. A tagged, traceable crab from a known small-scale fishery commands a real premium over a generic or imported snow crab, and the reasoning behind that premium is worth understanding before you spend money on it.
Female snow crabs are a separate, much smaller product, sold in the San’in region as seko-gani or locally in Kyotango as koppe-gani. Their season is shorter, closing around the end of December, and they’re valued mostly for their roe rather than leg meat. Most visitor-facing crab dinners feature the males.
When the Season Runs
| Date | Event |
|---|---|
| November 6 | Sea of Japan snow crab season opens by Ministry of Agriculture, Forestry and Fisheries ordinance |
| November 7 (typically) | First auctions, weather permitting |
| Late December | Female crab (koppe-gani) season closes |
| March 20 | Male snow crab season closes |
These dates are set by national fisheries regulation and don’t shift year to year unless the ordinance itself changes, which it hasn’t in recent seasons. The boats go out the night before opening day and begin fishing at midnight on November 6, so the very first crabs of the season are typically auctioned the following morning, though rough winter seas sometimes delay the first trip by a day or two.
Quality is generally considered best from November through February, when the crabs are at peak weight. By March, the season is still open but the crabs run slightly lighter.
Taiza-gani: Kyoto’s Own Brand
Taiza-gani is the snow crab landed specifically at Taiza Fishing Port in Tango-cho, part of Kyotango City. It’s caught by exactly five licensed small trawlers, all based at that one port, and the fishing grounds sit roughly 20 to 50 kilometres offshore from Cape Kyoga-misaki at a depth of 230 to 300 metres.
The short distance from port to fishing ground is the whole reason Taiza-gani has its reputation. The boats leave at night, fish, and return the same day, meaning the crabs go straight to auction within hours of being caught rather than sitting in a hold for a multi-day trip. Locals sometimes call it maboroshi no kani, “the phantom crab,” because the daily catch is small and tagged crabs sell out fast.
Every qualifying crab gets a green tag, fixed to the claw on board the boat, stamped with the words “たいざガニ” (Taiza-gani) and the name of the fishing boat. Crabs are graded on size, weight, shell color, and physical condition before they qualify. There’s also a minimum legal shell width of 10.5 centimeters, enforced for conservation reasons, below which a crab can’t be landed at all.
Why There’s Now a Second Tag on the Claw
In April 2024, a seafood company in Kyotango was found to have relabeled snow crab from a Hyogo Prefecture port with counterfeit Taiza-gani tags, and two people connected to the company were arrested under Japan’s Unfair Competition Prevention Act. In response, the Kyoto Prefectural Fisheries Cooperative introduced a second identifier for the 2024 season onward: a white plate carrying a QR code and a boat-specific serial number, fixed alongside the existing green tag.
Scan the code and you can check the landing date and the specific boat against the cooperative’s own records. It’s the first system of its kind in Japan for this kind of regional crab brand, and for a foreign visitor buying crab directly from a market or being served it at a restaurant, it’s a genuinely useful way to confirm you’re getting what you’re paying for. If a vendor’s crab has only the green tag and no white plate, it’s worth asking why.
What Crab Actually Costs
Pricing for Taiza-gani specifically is wide-ranging and driven heavily by scarcity, since only five boats supply the entire brand. At the November 2024 opening auction in Taiza, the highest lot recorded was ¥850,000 for five crabs, an average of roughly ¥170,000 per crab, reflecting first-of-season prices that domestic buyers pay for bragging rights as much as quality. Retail reporting on Taiza-gani elsewhere has cited individual crabs selling for around ¥40,000 at the high end outside of opening-day auction pricing.
For a realistic visitor budget, this translates to a wide range depending on exactly what you’re buying:
- A whole tagged crab bought directly from a market or fishmonger, outside of the opening auction premium, is the most cost-effective way to get genuine Taiza-gani.
- A restaurant crab kaiseki course built around a full crab per person will cost considerably more than the raw market price, since you’re paying for preparation, multiple courses, and the dining experience itself.
- Untagged or generic matsuba-gani, without the Taiza brand, costs meaningfully less than the branded product and is still a genuine, good-quality Sea of Japan snow crab.
If you’re staying somewhere with a kitchen, buying live crab directly from a fishing port market and preparing it yourself is worth considering purely for the freshness. It won’t come with the multi-course presentation of a kaiseki dinner, but the crab itself will be as fresh as it’s possible to get. This is the self-catering alternative worth weighing against a restaurant booking if ingredient quality matters more to you than the formality of the meal.
How a Crab Kaiseki Dinner Works
A full crab kaiseki dinner typically runs eight to twelve courses over two to three hours and centers on one whole crab per guest. The exact sequence varies by restaurant, but the general structure looks like this:
- Sakizuke — a small seasonal starter to open the meal.
- Otsukuri — raw crab leg meat, briefly chilled to firm the texture, showcasing the crab’s natural sweetness.
- Yude-gani — boiled crab leg sections served with a citrus dipping sauce.
- Yaki-gani — lightly grilled crab leg, offering a different flavour profile from the boiled version.
- Kani-miso — the crab’s hepatopancreas, often eaten with sake or used as a dip.
- Kani-shabu — crab meat briefly cooked in dashi broth at the table, dipped in ponzu.
- Kani-suki nabe — a hot pot combining crab, vegetables, and tofu.
- Zosui — rice porridge finished in the leftover broth from the nabe, often the highlight of the whole meal.
- Dessert and tea to close.
Most restaurants provide long-handled crab spoons and kitchen scissors for extracting meat from the shell, and staff will usually demonstrate at the first course if you look unfamiliar with the process. There’s no awkwardness in asking. A full kaiseki dinner is a two-to-three-hour commitment, so it’s worth planning the rest of the evening around it rather than trying to fit in anything else afterward.
Where to Base Yourself for a Crab Trip
The three major snow crab destinations along the San’in coast are Kinosaki Onsen in Hyogo, the Tango Peninsula in Kyoto, and the Tottori coast, and each has a distinct character.
Kinosaki Onsen is the highest-volume crab destination, with the largest concentration of ryokan and crab-focused restaurants, and it books up earliest as a result. Tottori has the largest total crab catch of the three regions and its own top-tier brand. The Tango Peninsula, by comparison, is quieter, has fewer packaged crab tours, and is the only place you can get genuine Taiza-gani, since it’s tied to a single fishing port.
For visitors who want direct access to that specific brand and a quieter overall experience, the Tango Peninsula makes the most sense. Asobi Lodge is within Kyotango City itself, a short coastal drive from Taiza Fishing Port, which makes a market visit or a booked restaurant meal an easy addition to a stay rather than a dedicated day trip.
Day-tripping to the peninsula from Kyoto City for a crab meal alone is possible but takes most of a day round-trip, so an overnight stay is the more practical option if you want to actually enjoy the area rather than just the meal. The transport guide covers how to get here, and the Kyotango winter travel guide covers the season more broadly.
Booking Notes
A few practical points worth knowing before you plan around crab season specifically:
- Book restaurants well ahead for the opening weekend. Domestic demand around November 6 to 7 is intense, and the better local restaurants take reservations two to three months out for that window.
- Mid-week dates are less crowded and often better value than weekend dates throughout the season.
- Shellfish allergies are a genuine consideration. Ask restaurants directly whether an alternative course is available; don’t assume.
- Crab dinners run late. Rural restaurants don’t always have easy taxi access, so confirm how you’re getting back to your accommodation before the meal starts.
For the wider seasonal picture, see the autumn pillar guide, which covers the overlap between foliage season and the crab season opening, and the Kyotango restaurant guide for the broader local food scene beyond crab.
Frequently Asked Questions
Is Taiza-gani worth the extra cost over generic matsuba-gani?
If you care about provenance and the story behind your food, yes. If you just want good snow crab without paying a scarcity premium, a generic tagged matsuba-gani from the same region is still excellent and considerably more affordable.
Can I buy crab without booking a full restaurant meal?
Yes. Taiza Fishing Port and other Kyotango fishing ports sell crab directly to the public on landing days, and walk-in visitors are welcome at the market.
How do I know a crab labelled Taiza-gani is genuine?
Look for both the green tag and, since the 2024 season, the white QR-coded plate. Scanning the code lets you confirm the landing date and boat against the fisheries cooperative’s own records, which is a direct response to a real labelling fraud case from 2024.
What’s the difference between matsuba-gani and king crab?
Different species entirely. Matsuba-gani (snow crab) has long, thin legs and delicate meat. King crab (taraba-gani) has thicker legs and a heartier texture. Both appear on Japanese winter menus, but for the San’in regional experience specifically, snow crab is the local product.
Does Asobi Lodge serve crab dinners?
No. Asobi Lodge is self-catering, so Hamish and Nora don’t prepare meals for guests. The arrangement most guests use is buying live crab from a nearby fishing port market and preparing it themselves at the property, then reserving a restaurant kaiseki dinner on a separate night of the same trip for the full formal experience.
Is crab kaiseki suitable for vegetarians?
Not really. Most crab kaiseki menus are built almost entirely around the crab itself, and there’s little to substitute. Pescatarians are of course fine, since crab is shellfish.
