They open from around 5:30 in the evening. There was a post saying the restaurant wasn't open, but that's not the case; they operate at night. If you call and reserve beforehand, they'll cook and prepare the suppon to coincide with your arrival. There's parking too. (Ask the staff where it is.) Besides suppon dishes, of course, there are individual dishes such as moray eel karaage and sea turtle sashimi that you can only eat at Tosaichi, making this one of the places I want to visit regularly. The food is delicious, so many customers also come from outside Tokyo through word of mouth. I'll come back to see the owner, mama, and their daughter! Full again today! Thanks for the meal.

【Wow! Found an incredible place!☆A long-established suppon restaurant founded 53 years ago】 Sazumachi, Chofu, Tokyo. A restaurant offering a wide range of dishes, from suppon to assorted sashimi, tempura, karaage, kappo small plates, and drinking snacks. According to the proprietress, it was founded 53 years ago. The nearest stations, though quite far away, are Fuda or Chofu on the Keio Line. Wow! I managed to find an incredible place♪︎♪︎♪︎✧٩(｡•̀ᴗ-)人(-ᴗ´•｡)۶✧Yay‼ This place has always been in my neighborhood but remained a mystery. When walking my dog along Nogawa, I'd see its lights on at night, so it was definitely operating. But the “suppon cuisine” sign, location, and exterior made it rather intimidating for first-timers(´･ω･`; ) This time, I took the plunge and visited with 4 members of our Chofu dining group. P from Kokuryo called to reserve and checked the suppon prices and opening hours, which was a great help(人´∀`*) On the reserved weekend day near year-end, we met outside. Opening the door revealed such a homely atmosphere(*´-`) It's a family operation: the owner, his wife, and their daughter. Their daughter is a little older than us, and we had lively conversations about local junior high schools (we all attended different ones) and saunas. It was simply great fun(๑˃̵ᴗ˂̵)و ◆Today's order◆ 1 whole suppon　14000 yen Fresh suppon blood juice (mixed with apple juice) Suppon gallbladder and heart Suppon meat and liver sashimi Suppon hot pot (with eggs) Suppon zosui Simmered suppon empera (the soft edge of the shell) Appetizers Salmon sashimi Kinmedai sashimi Moray eel karaage　800 yen Chicken karaage Simmered daikon Bottled beer Sake Soft drinks Only known prices are listed. About 3 hours for 4 people came to a little over 26000 yen. 1 suppon serves 3–4 people. First, a beer toast!(*´꒳`)_∀*” The appetizers included scallops and shiraae. Then the suppon course began. The proprietress told me to swallow the suppon gallbladder without chewing, but I chewed it (haha). Bitter( ・∀・) The raw meat and gall sashimi had no strong taste and were easy to eat. Perfect drinking snacks. Besides suppon, we ordered salmon and kinmedai sashimi. I love kinmedai♪(´ε｀*) They'd received some good moray eel from Kochi, so we had it made into karaage. This was delicious too(´ρ`) Such a refined flavor, unimaginable from its grotesque appearance. We ordered chicken karaage as well. Now, finally, today's main event: suppon hot pot. Besides the meat, of course, this suppon was female, so there were plenty of yellow eggs. The whole pot became golden soup(〃´ω`〃) The meat was springy, without a strong taste, perhaps similar to chicken. Such wonderful stock♪︎So delicious♪︎(๑´ڡ`๑) Naturally, we finished with zosui, the perfect ending. And an extra on the house? We even received simmered empera, the soft edge of the shell, and simmered daikon(人´∀`*) Well, Tosaichi delivered 120％ satisfaction. I'd absolutely love to visit again♪︎ #Yokozuna #SupportLocal #HiddenGem #SupponCuisine #KappoSmallPlates #KaisekiCuisine #FishAndSeafood #Karaage #Tempura #MorayEelCuisine #WhaleCuisine #NearNogawa #MitakaDori #SupponByReservation #TatamiSeatingAvailable #CashOnly #FamilyRun #PlaceIdRatherKeepSecret #YearEndParty #Marunabe(SupponHotPot) #UnnecessarilyBoostedMyVitality #VeryLikelyToReturn

As of October 19, 2025, it's unclear whether it's operating. I haven't seen the lights on for about 10 years.

A place I visit regularrrly. The suppon dishes have no unpleasant smell at all and are very delicious! Besides suppon, there are delicacies like green sea turtle sashimi and moray eel karaage. There were various other drinking snacks too. Payment is cash only. I'll visit agaaain!

A place I visit regularly because even alone, I can take my time enjoying delicious food at the counter＾＾
