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

#trademark

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.

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.

“DISPEN PAK” to ‘PAKITTE’

  • October 29, 2025
#trademark

Over ten years ago now, we featured the “Dispense Pack” on our firm’s blog.
Convenient Container: DISPEN PAK (Hiro)

“DISPEN PAK” is a small container for seasonings and such. Its structure allows you to snap it in half with one hand, releasing the contents. (For details, see our previous article.)
Since this article still gets occasional visits, we assume many people remain interested in this product.

PAKITTE

PAKITTE

This “DISPEN PAK” was renamed “PAKITTE” in 2019. ‘Pakitte’ is a product of DISPEN PAK JAPAN CO., INC., a group company of Kewpie Corporation. You can see the small text “Pakitte (in Katakana) TM” printed on the product.

PAKITTE

The name origin is easy to imagine, making it memorable and approachable. While many may have seen the container, few remembered it as “DISPEN PAK.” The name “PAKITTE,” which seems poised to gain recognition, underscores the importance of effective naming. Naturally, “Pakitte” is trademarked, protecting the brand.
Pakitte (in Katakana): Japanese Trademark Registration 6334755
PAKITTE: Japanese Trademark Registration 6268828

Incidentally, “PAKITTE” has also become a capsule toy (available sequentially starting September 2025). Now you can “pop” it to your heart’s content, over and over again! ♪

My favorite character was trademarked!♪

#trademark

In my March 2023 blog post “Chiikawa,” I mentioned that my favorite character is Chiikawa’s friend, Usagi.
And guess what! That favorite character was trademarked!

The trademark holder is listed as “Nagano Co., Ltd.” The Chiikawa trademark (Japanese Trademark Registration No. 6462301) I introduced in my previous article also had its trademark rights transferred to “Nagano Co., Ltd.”

I felt reassured finding out that something I love is protected by rights.

The Tiny Trademark on Masking Tape

  • October 15, 2025
#trademark

Masking tape is incredibly handy for sticking little things or sealing envelopes. Whenever I see cute designs, I just can’t resist buying them.

Masking Tape

The masking tape I bought recently had the word “Trademark” printed in very small letters. I looked it up on J PlatPat and found that Nichiban Co., Ltd. had registered the rights for “Petit joie”. (Japanese Trademark Registration No. 5746465)
Of course, just because the printed size is small doesn’t mean the rights are small!

Masking Tape

Nichiban, which has a factory in Anjo City, Aichi Prefecture, is famous for “Cello Tape.” It’s so well-known that people often mistake it for a generic term, but “Cello Tape” is also a Nichiban trademark; the generic term is “cellophane tape.” There are several Cello Tape trademarks, with the oldest registered in 1959 (Japanese Trademark Registration No. 546229).

Cellotape is an essential item, and I’d like to buy Petit Joie masking tape again if I find it. (Marron)

I recently visited Kyoto for some business.
Since I was there, I took the opportunity to do a little sightseeing too.

Since I was there, I also had some udon noodles typical of Kyoto (Kansai).

Since I was there, I also visited my favorite Japanese sweets shop.
It’s “Demachi Futaba,” famous for their Nadai Mamemochi.
Everyone comes here aiming for this sign.

Besides the signature mame mochi, I bought “Fukumame Daifuku” with sweet potato paste, “Yomogi Dango” (mugwort dumplings), and “Shin Kurimochi” (fresh chestnut mochi).

I took these photos after carrying them around for a few hours, so they might not look as appetizing as they were, but everything was delicious and truly impressive. No wonder there’s always a line out the door.

This time was a whirlwind visit, but I hope to return when autumn deepens and enjoy a leisurely Kyoto sightseeing trip while admiring the autumn leaves.

The trademark “Demachi Futaba” is registered as of February 20, 2009 (Japanese Trademark Registration No. 5205944), with the designated services being “the provision of benefits to customers in the retail or wholesale business of mochi and red bean rice.”

Ballpoint Pen Drawings

  • September 29, 2025
#Inventions of the Day #patent

Today (September 29th), I will introduce an invention closely related to this date.
This time, I will feature the ballpoint pen.

September 29th marks the birthday of Hungarian-born inventor László Bíró (1899.9.29-1985.10.24), who obtained the first practical ballpoint pen patent.
 That said, the technology behind ballpoint pens and the story of László Bíró are already widely known (1, 2). Therefore, this time I will introduce ballpoint pens as an art medium (ballpoint pen drawings), which is quite different from their image as writing instruments.

We rely on ballpoint pens daily, both at work and home. But haven’t you ever gotten annoyed when the ink clogs and your writing gets messy? I certainly have (laugh). For someone like me, it’s hard to believe those beautiful drawings above could be created with that same ballpoint pen.
Even if such artistic use seems impossible, using a Spirograph gear-based drawing tool? seems like it could let amateurs create pretty patterns.

Incidentally, the Spirograph we know today is an educational toy developed by English inventor Denys Fisher (3, 4(PDF)). It became a craze in Japan in the late 1960s (Showa Era year 40s). Nowadays, similar products are sold under names like “Spinning Ruler” or “Design Ruler”.

Celebrating a 60th Birthday with a Touch of Wit

  • September 17, 2025
#trademark

While searching online for a small gift to celebrate a relative’s 60th birthday, I stumbled upon something uniquely funny.

When it comes to Kanreki (60th birthday) celebrations, there’s a custom of wearing a “red chanchanco (Japanese padded vest)”. Red is considered a color that wards off evil spirits and brings good fortune, so I thought “something red to wear” would be perfect. An invisible red belly warmer seemed like something they could easily use.
That’s when I found this belly warmer – the one that made me think, “This is it!”

red belly warmer

This belly warmer is an original, customizable product designed, produced, and sold by Shalemon Co., Ltd., located in Yatomi City, Aichi Prefecture.
You can have names or other text printed in the blurred area.
Additionally, it comes with a celebratory “noshi (gift wrapping) paper” attached to the back, making it ready to hand over as a gift.

red belly warmer

The phrase “kanreki damono” printed on the belly warmer is a registered trademark of Shalemon Co., Ltd.
The company logo in the lower left corner, though color-inverted, is also a registered trademark.
They hold 17 other registered trademarks and have 5 trademarks pending, firmly protecting their original brand while offering a wide range of uniquely humorous underwear.
If you’re interested, why not take a look at their official online shop?

When we gathered for the Obon dinner, I was able to hand it over safely, and both the recipient and everyone else broke into smiles.
By the way, the gathering was held at “Unagi Kappo Mikawa Sansuitei” in the Mikawa Isshiki area of Aichi Prefecture. It’s a restaurant where you can enjoy delicious eel at a great value, and it’s one of the three shops collectively known as the “Mikawa Isshiki ‘Eel Big Three’”. The logo mark “Mikawa Isshiki/Eel Big Three” is also properly protected as a registered trademark and was part of their brand strategy!♪ (Cacao)
