The Secret of “tonton” — Slow-Cooked Tosa Pork at Its Finest

Premium local ingredients
The pork comes from Sukumo in western Kochi, raised in pure mountain water and lush nature. The result? Tender, juicy meat with a natural sweetness unlike anything you’ve tasted before.

Even the rice is special — a blend of Koshihikari from Tosa Yamada and “Towanisiki” fragrant rice from Shimanto.Koshihikari from sunny Tosa-Yamada, known for its chewy texture and natural sweetness, and “Towanishiki,” a fragrant rice from the misty, temperature-shifting valleys of Kubokawa in Shimanto Town. The combination creates the perfect balance for their pork dishes.Their subtle sweetness perfectly complements the pork steak.


Revolutionary Low-Temperature Cooking

At tonton, the pork is vacuum-sealed and slowly cooked in water at 40–60°C.
This method prevents shrinkage and moisture loss, keeping the meat tender and flavorful. After sous-vide, it’s briefly seared to bring out the aroma — served at the precise temperature where humans sense the most umami.


Cozy Atmosphere — A Place You’ll Want to Call “Home”

The restaurant’s concept is “everyone’s home to return to.”
Bright wood interiors, counter and table seating — whether dining solo or with family, the space feels warm and welcoming.


The Star Dish — Customizable Pork Steak Sets

Choose from 200g, 300g, or 400g portions, served as a set meal with rice, soup, and side dishes.

Signature Sauces (5 types):

  • Tosa Saga natural sea salt 🧂 (chef’s top recommendation)
  • Soy sauce flavor
  • Tosa-style white miso
  • Ginger sauce
  • Special limited-edition sauce

SacChi’s Recommendation — 200g Pork Steak with Tosa Saga Sea Salt

I went for the 200g portion with Tosa Saga sea salt, and it was love at first bite.
The pork was incredibly soft — even the fatty parts melted gently, rich yet refined. The mineral flavor of the salt enhanced the meat’s sweetness, and I couldn’t stop eating.


Thoughtful Customization

The team accommodates every guest’s preference:

  • Trimmed fat for those who prefer lean meat
  • Sauce level (extra / light)
  • Garlic chip removal
  • Rice portion adjustment
  • Extra sear for those avoiding pink meat
