On October 1, 2026, Kawakami Sangyo, the company behind Japan’s trademarked PutiPuti® bubble cushioning, changed its corporate name to PutiPuti Co., Ltd.
On the surface, it is simply adorable.
“Hello, we are Kawakami Sangyo” became “Hello, we are PutiPuti.”
It sounds less like a corporate rebrand and more like someone added a sound effect to the business card.
But the story is much better than that. This was a serious attempt to fix an unusual branding problem: almost everyone in Japan knows the product name, while far fewer people knew the company that made it.
And this is not a tiny novelty manufacturer. It is a substantial industrial company.
1. So what does PutiPuti Co., Ltd. actually do?
The former Kawakami Sangyo traces its bubble-sheet research to 1963, began operations in 1968, and was incorporated in 1976.
Its cushioning was not originally called PutiPuti. It was sold under the name “Air Bag.”
The problem was that customers understood the material faster when staff described it as “that puchi-puchi popping stuff.”
Eventually the obvious answer won.
In 1994, PutiPuti® became a registered trademark.
The generic category is bubble cushioning material. Competing manufacturers exist: Sakai Chemical Industry sells products such as Minapack® and Air Cap®, while Izumi sells Air Cell Mat.
So technically:
bubble cushioning = category
PutiPuti® = this company’s trademarked product
In daily Japanese, however, “putiputi” is so familiar that people often use it almost like the generic name of the object itself.
That is an extraordinary branding position.
2. Did this company invent bubble wrap?
Not globally.
Bubble-sheet technology existed in the United States before Kawakami Sangyo entered the field. Company interviews say the founder noticed publicly available US bubble-sheet patent technology, then developed an independent production method suitable for mass production in Japan.
The company describes itself as the first in Japan to independently manufacture and sell its type of bubble cushioning.
So the clean version is:
It did not invent the global concept.
It became a Japanese pioneer and built the PutiPuti® brand into a household name.
3. How large is the company?
Its official figures for September 2025 are surprisingly substantial:
- Revenue: ¥17.1 billion
- Employees: 546
- Capital: ¥99.29 million
- Share of the domestic bubble-cushioning industry: about 60%, according to the company
- Product variants: more than 1,000
- PutiPuti production plants: seven nationwide, according to the official FAQ
This is not a tiny packaging shop that happened to go viral.
It is a major manufacturer with more than half of its domestic category.
That does not mean any random sheet you touched in Japan had exactly a 60% chance of being theirs. Supply chains vary by industry, region, retailer, and year.
But if you have lived in Japan and handled bubble cushioning for years through deliveries, moving, electronics, factories or offices, it is entirely plausible that you have handled their products many times without knowing the company name.
The company was hiding in plain sight.
4. Why abandon the name Kawakami Sangyo?
Because the brand-company gap had become absurdly large.
The company has explained that PutiPuti has enormous recognition, while Kawakami Sangyo was much less widely recognized.
The situation was basically:
Customer: “I know PutiPuti.”
Company: “That’s us.”
Customer: “Wait, you’re Kawakami Sangyo?”
The valuable brand asset was sitting right there, while the corporate name lived somewhere else.
The October 2026 rebrand, the first in the company’s 58-year history, connects product brand and corporate brand directly.
There is also a sustainability reason. The company runs a Loop Recycle® program that collects used PutiPuti® and returns it to production. It reports recycled-material use rising from 44% in fiscal 2008 to 98% in fiscal 2025, cushioning-material collection growing from 20 tonnes in 2023 to 198 tonnes in 2025, and recycling boxes increasing from 20 in 2021 to 404 in 2025.
The company wants “PutiPuti” to mean not only something it manufactures, but also a material it collects and circulates.
That story is much easier to tell when the company itself is called PutiPuti.
5. Why did the rename go viral?
Cute helped. But familiarity did most of the heavy lifting.
People already know the object.
They have seen it.
Touched it.
Popped it.
They can hear the sound in their head.
Then the company says:
“From today, we are PutiPuti Co., Ltd.”
The joke lands instantly.
The official X account also turned the announcement into participation: “one like = one pop,” promising to pop one bubble for every like counted by October 8.
A corporate registration event became an internet game.
On the same day, the company launched a Simeji keyboard collaboration with PutiPuti-themed skins, typing effects and an X campaign.
The rollout was built for sharing, not merely announcing.
6. What does viral attention actually do for the business?
Here we move from reported facts to marketing analysis.
The biggest benefit is mental linkage.
Before:
PutiPuti = familiar product
Kawakami Sangyo = unfamiliar company
After:
PutiPuti = product
PutiPuti Co., Ltd. = company behind it
That can help corporate awareness, branded search, recruiting, trade-show communication, press coverage and participation in recycling programs.
It also generates earned media. A name change that would normally be administrative paperwork becomes a story other people distribute for free.
But viral views are not the same as revenue.
To judge commercial impact, you would still want to track search volume, inquiries, sales, recruiting applications, recycling participation and corporate-awareness surveys.
What we can say now is simpler: the rename was noticed. Very loudly.
7. And then Spanish adds a bonus problem
The English corporate name is PutiPuti Co., Ltd.
In colloquial Spanish used in Spain, reference works record puti as a shortening of puticlub, a word for a prostitution venue. That gives some Spanish speakers an unintentionally risqué association.
But saying “PUTI is obscene everywhere in the Spanish-speaking world” would be wrong.
ASALE’s Dictionary of Americanisms, for example, records a completely different Bolivian meaning of puti referring to a cooked food.
So this is a regional language issue, not a universal Spanish rule.
Japan sees: “PutiPuti Co., Ltd. — cute.”
Some speakers in Spain may see: “Hold on. That spelling does something else here.”
The rebrand accidentally came with an international-linguistics expansion pack.
8. Why this rename is genuinely interesting
The story is not just “a company chose a cute name.”
It spent decades building a product name until the product name became more famous than the corporation.
Then it moved the corporation toward the product.
Kawakami Sangyo became PutiPuti Co., Ltd.
Written down, it looks like a joke.
As brand architecture, it is remarkably logical.
And the strangest part may be us.
Many people in Japan have popped these bubbles since childhood, unpacked deliveries wrapped in them, or used them when moving.
Yet they never knew who made them.
Then one headline appears and the reaction is:
“Oh. It was you this whole time.”
The strongest asset in the rebrand is not the new name itself.
It is that the new name connects instantly to decades of physical memory.
