Couldn't load pickup availability
Ma-Tsubugai, or the "True Whelk," is widely regarded as the highest grade of edible sea snail in Japanese cuisine. Harvested from the cold, nutrient-rich waters of Hokkaido and the northern coasts, our True Whelk is prized for its impressive size, incredible sweetness, and signature "crunch."
- Texture: Exceptionally firm and crunchy—a texture highly celebrated in sushi culture.
- Taste: A deep, concentrated ocean sweetness that fills the palate with every bite.
- Aroma: Fresh and briny, reminiscent of the cold northern sea.
- Sashimi (The Gold Standard): Slice thinly and serve with a dash of soy sauce and wasabi. This is the best way to experience its famous crunchy texture.
- Sushi: A premium topping (Neta) found in high-end sushi omakase.
- Robatayaki (Charcoal Grilled): Grill with a mixture of soy sauce and butter for a savory, smoky treat.
- Tsubu-meshi: Cooked with rice and ginger for a comforting, umami-rich seafood rice bowl.
- Origin: Hokkaido / Northern Japan
- Status: Fresh / Wild Caught
- Size: Selection of Large, Premium-grade shells
- Storage: Keep refrigerated at 0-4°C and consume promptly for the best sashimi experience.
When preparing raw, please ensure the salivary glands (which contain natural tetramine) are removed. For those unfamiliar with the process, we recommend purchasing our pre-cleaned fillets or consulting a professional.
We source only "Ma-Tsubu" (the true species), ensuring you don't receive lesser substitutes. Each shell is selected for its weight and vitality, delivering a true taste of Japanese luxury seafood to your kitchen.

Dynamic Pricing & Deposit Policy
- Weight Variation: Our specialty items, such as fresh seafood and Wagyu beef, inherently vary in weight.
- Pre-order Deposit: To accommodate these variations, prices are initially set based on the maximum expected weight. A 20% deposit is charged at the time of your pre-order to secure your purchase.
- Final Capture & Remaining Balance: Once the actual weight is confirmed after sourcing and shipping from Japan, we will capture the exact amount for the final, correct price.
- Effective Refund for Excess: This process ensures you only pay for what you receive. Any excess amount from the initial estimate is simply not captured (functioning as an effective refund).
