This is the place for fatty tuna at Kuromon. They are suppliers of chefs and vendors in the area and they offer cuts to the public for great prices. I enjoyed the sampler of three different cuts so I could compare them. The otoro was amazing but I was just as happy with the chutoro. It wasn’t quite as melt in your mouth as the otoro but the flavor was incredible. Highly recommended.

I came here with my family back in February 2023, and it was just fantastic. Yesterday I had the pleasure of visiting Kuromon market again and this place was a must. They are the only tuna stand that sources their own tuna from what I could see. It would not surprise me if the other seafood stands in the market sourced their tuna from here. You can buy very generous portions of every cut of tuna for very reasonable prices. I bought two boxes of chu-toro for a total of ¥2800, which in the UK would barely get you 3 pieces of chu-toro nigiri. The cuts were chunky and well with the money here, they are all cut on premises in the morning. I highly recommend this place if you want the freshest cuts of tuna sashimi. The old gentleman that works here is such a lovely guy, have a chat with him while you eat.

Super duper friendly stall owner! This store is unique, more of a fishmonger~ So you know the fish is ULTRA fresh, and it rlly is, we went back twice durinf our 3 day stay! And the prices are more affordable to be honest~ you rlly get the best quality for the price you pay~ personally super love otoro which is only a wooping 800 yen for 6 THICC cubes! LOVE LOVE LOVE Just FYI: Kamatoro (Cheeks) - 3 thick slabs (1000 yen) Otoro - 6 cubes (800 yen) Assorted (2 thick slabs of 4 types) - 2500 yen ^ for 3 people Low fat —> fattiest - Reddest, chutoro, otoro, kamatoro There is a standing eating area on the right with tables Marbling is WOW for the fatty cuts

Very fresh tuna, with friendly and attentive shop owner. The set of 4 different cuts was delicious, especially with nori!

If you're cool with standing up and just quickly gulping down some high quality sashimi off some plastic and styrofoam, this is the place to do it. Best culinary experience of my Japan trip so far.

This place is a gem - no frills, GOOD & fresh tuna at very good prices. They’re a fishmonger specialised in tuna and sea urchin and their expertise is on full display. Tuna on offer from various regions of Japan. Just select your tuna and consume straight at the metal tables at the entrance. Cash only though.

Best place, specialize for Toro, fatty tuna, for more than 70 years. Best value compare to surrounding shops. It's a fish monger where you can buy slice bit and eat it there. Highly recommended when you are visiting the area.

Very delicious and good price. Local and cute restaurants. I love it so mich Edit 6 June 2025 : This is my second time in Osaka, and I couldn’t miss the chance to come back to this restaurant again! Still just as impressed as the first time — I really love it!
