What is the popular TV anime “Osomatsu-san”?

In 2015, as a commemoration of Fujio Akatsuka’s 80th birthday, the TV anime “Osomatsu-san” was created, based on Akatsuka’s classic gag manga “Osomatsu-kun,” depicting the six brothers as adults. Even though they’re over 20, they’re still worthless, unemployed, and virgins…

But somehow they’re endearing, and their unpredictable daily lives have made them, before we knew it, the most famous sextuplets in Japan! This year marks the 10th anniversary of that shocking broadcast start.

New friends? New trouble? And a new side of the sextuplets…? The live-action film “Osomatsu-san: The Human Scum-Turning Plan!!!!!?” will be released in June 2026.

What is Okinawa Shokudo “Yappari Steak”?

“Overwhelmingly delicious, thick, and tender.”

Yappari Steak is an Okinawan restaurant chain operating under the concept of “From Okinawa to the world.” Currently, it has approximately 20 stores not only in Japan but also overseas, bringing Okinawan steak culture to the world.

What we value most is the “handcrafted quality” we offer, where our butchers prepare each piece of meat by hand in-house.

The misuji used in our signature “Yappari Steak” is a rare cut of meat, with only about 5kg available from a single cow. By carefully processing it by hand, without relying on machine processing, and carefully observing the delicate way the sinews are arranged, we achieve a surprisingly tender texture despite its thickness, and bring out the full flavor of the cut.

Take this opportunity to enjoy an “overwhelming meat experience” showcasing the skills of our chefs, along with our collaborative menu.
