Katsuo Shokudo ~The Ultimate Bonito Flakes Experience~

During a recent business trip to Tokyo, I dined at “Katsuo Shokudo” in Shibuya. I had previously assisted this establishment with trademark registration at our office, so I’d long wanted to visit to say hello.

Upon entering at my reserved time, I was immediately greeted by the pleasant sound of “shuu, shuu, shuu” as owner Ms. Nagamatsu shaved katsuobushi (bonito flakes).

At the counter, Ms. Nagamatsu shaves katsuobushi freshly for every order for each customer.
Shortly after placing my order, the “Katsuo Shokudo Set Meal” arrived: a bowl piled high with freshly shaved, fluffy katsuobushi atop rice, accompanied by miso soup and an egg.
The ultra-thin, pinkish katsuobushi had an exceptional aroma and melted instantly in the mouth. The skill required to shave bonito this thinly and uniformly is truly masterful. Watching the katsuobushi being shaved live and tasting such beautifully fresh, delicious flakes was a first-time experience for me. The miso soup, rich with bonito broth, was also exquisite.

From Ms. Nagamatsu, who also works as a katsuobushi evangelist (“Katsuo-chan”), you can hear many fascinating stories about the origins of katsuobushi and the process involved in making it. She explained that the plane used for shaving depends on the day’s temperature and humidity. Picking up a partially shaved piece of bonito placed on the table, I was surprised by its substantial weight and hardness; the shaved surface resembled wood grain. Seeing and touching the real thing for the first time was an incredibly valuable experience.
Katsuo Shokudo has been listed in the Bib Gourmand section of the Michelin Guide Tokyo for four consecutive years: 2022, 2023, 2024, and 2025 (MICHELIN GUIDE: Katsuo Shokudo). Its selection as a restaurant offering “satisfaction beyond the price” (Bib Gourmand) is well deserved, given its quality and experience.

I was delighted to see the registration certificate for the trademark (Japanese Trademark Registration No. 6957190) displayed inside the restaurant, which we had assisted in applying for and registering. The bonito illustration for this trademark was created by Ms. Nagamatsu’s grandmother, who inspired her to start this business and the restaurant. I recalled her words when she requested the application: “This illustration symbolizes the restaurant’s identity, so I definitely want to trademark it.” This illustration, imbued with Ms. Nagamatsu’s passion, will continue to support the restaurant as its signboard and symbol.

I sincerely hope Katsuo Shokudo, which conveys the appeal of katsuobushi, a traditional Japanese ingredient, to future generations, continues to thrive and endure for many years to come (Hiro).

Waymo Self-Driving Taxis

Did you know there are self-driving, driverless taxis?

While not in Japan, companies like Waymo—part of Alphabet Inc., the same parent company as Google—are actually operating self-driving taxi services in urban areas like San Francisco and Los Angeles in the United States. Just like Uber taxis, which are now widely used in Japan, you simply download the app, enter your pickup location and destination, and Waymo will come to pick you up just like a regular taxi. Since your credit card information is linked during app registration, payment is automatically processed after the ride, eliminating any hassle.

A friend recently rode one. They found it strange there was no one in the driver’s seat, but said it arrived safely at their destination just like a regular taxi. They also enjoyed the comfort of not needing to tip—a must in the US—and not having to worry about the driver. Differences from regular taxis include opening/closing doors via the app, the vehicle starting automatically once you fasten your seatbelt, being able to set your preferred music genre after boarding, and knowing the estimated arrival time, making it seem more convenient.

Waymo appears to be a global pioneer in autonomous driving, holding numerous patents including Japanese Patent Registration No. 7712751 (Thermal imaging for self-driving vehicles) and Japanese Patent Registration No. 6985523 (Determining and responding to internal conditions of a vehicle).

In Japan, test drives have begun in Tokyo. I think it would be convenient not only for tourist areas but also as taxis for the elderly in depopulated areas, or as privately owned vehicles that even people with limited mobility could drive, enabling their use for picking up and dropping off children. I look forward to the continued evolution of autonomous driving technology. (Chamomile)

Chocorooms

It’s swimmer.
It’s autumn. And autumn means mushrooms. The mountain delicacies of this season are delicious, and I want to eat lots of them, but amateurs can’t just casually go mushroom hunting.

So, the mushroom anyone can safely get in the city is “Chocorooms (Kinoko no Yama),” right? Even as an adult, picking up these adorable mushroom-shaped snacks still makes me feel excited.

This universally recognized, iconic snack shape was registered as a word trademark in 1978 (Japanese Trademark Registration No. 1330075) and as a three-dimensional trademark in 2018 (Japanese Trademark Registration No. 6031305).
Precisely because of its distinctive and appealing shape, the company diligently protects its rights.

As previously covered in our office blog, “Takenoko no Sato” registered its three-dimensional trademark in 2021 (Japanese Trademark Registration No. 6419263).

Dimension Transfer Device

  • November 5, 2025
#Inventions of the Day

Today (November 5th), I’d like to introduce an invention closely related to this date. It’s the “Dimension Transfer Device” invented by Dr. Emmett Brown.

When a vehicle equipped with a dimension transfer device is traveling or flying at 88 miles per hour, passing 1.21 gigawatts of power through the device enables dimensional transfer—that is, time travel—to the date and time set on the time circuit.

Dr. Brown conceived the theory for the time machine and the Time Circuit needed to make it work on November 5, 1955, when he slipped while trying to hang a clock in the bathroom and hit his head on the toilet. It reportedly took him 30 years and his entire fortune to bring it to fruition.

Of course, this is all fiction from the movie “Back to the Future”.
The DeLorean is cool.
