Maybe your child suddenly announced they want a “Mellojoy,” and that was the first you’d heard of it. When a trend seems to appear overnight through social media or friends, parents are often left wondering: What is this? Where do you buy it? Is it okay for my child to play with?
Mellojoy is a squishy — a soft, squeezable toy — described as originating in China. In 2026 it landed at #2 in a trend survey of elementary and middle-school students, making it one of the toys that defines what kids are into right now.
Because it’s a popular item, though, you’ll also find products online with different sellers and prices. And in August 2026, the U.S. Consumer Product Safety Commission (CPSC) issued a safety warning about fake and counterfeit squishies in general.
That said, the CPSC warning was not a recall of genuine Mellojoy products. Reading it as “a warning came out about squishies, so Mellojoy is dangerous” isn’t accurate either. So in this article, we separate the facts and lay out the price, purchase routes, signs that suggest a counterfeit, and the points to check for playing safely.

What is Mellojoy? Why this Chinese-origin squishy is popular
Mellojoy is a squishy with a soft feel, using motifs such as food and characters. In a 2026 survey of elementary and middle-school students, it was introduced as a “new-texture item originating in China” and placed #2 among “other things and trends that caught on.”
How it relates to squishies (feel and play)
First, Mellojoy is a type of squishy toy, not a separate toy category of its own.
Squishies come in many forms — some are a sponge-like material you squeeze, some hold gel inside, and more. What sets Mellojoy apart is that, beyond the soft feel when you press or squeeze it, it combines pleasures other than touch: a look that suggests bread or sweets, and blind-box-style products.
As of August 16, 2026, the MellojoyJapan website listed products such as “Butter,” “Rabbit Sakura-Mochi,” “Fluffy Marshmallow” and “Yukata Sheep,” with several described as “blind box toys.”

Some media also describe a style of enjoying the feel through a soft dedicated bag. But as far as our editorial team could confirm, we could not find a unified statement that “playing through the bag” is the official standard way to use every product. When your child actually plays with it, follow the usage described on the product you bought and on its packaging.
In other words, the appeal of Mellojoy isn’t simply that it’s “soft.” Part of the appeal is that kids can squeeze it, choose it, unbox it, collect it, and show it to friends.
Why it’s popular with elementary- and middle-school-age girls
Mellojoy’s popularity isn’t a phenomenon happening on social media alone.
In the “First-Half 2026 Trend Ranking” run by Girls Lab — the reader community of the magazines nicola and Nico☆Puchi — among elementary and middle-school members, in the category “other things and trends that caught on,” Mellojoy came in #2, behind the top entry of “sticker books / sticker trading / Bonbon Drop stickers.” There were 512 valid responses.

The same announcement analyzes that, amid a Heisei-era revival, once-popular sticker books and squishies are drawing fresh attention in new forms, and that new texture-focused toys such as Mellojoy are spreading.
This is an interesting point for thinking about what kids are into now. Even as smartphones and short videos have become a given, some of the trends gaining traction among children in Japan in 2026 — sticker trading, squishies — center on physical experiences: touching, collecting, holding, showing.
Adults tend to look at a toy and think, “What’s it for?” But for a child, usefulness isn’t the only value. “I want to touch it,” “I want to collect it,” “My friends know about this too” — those shared experiences can be part of the fun.
So when your child wants a Mellojoy, rather than starting from “it’s something I don’t really know, so no,” it’s easier to talk if you first understand (“so this is what’s fun right now”) and then check the purchase method and safety together.
How much does Mellojoy cost, and where can you buy it?
Mellojoy’s price and sales method change by product and by timing. When we checked the MellojoyJapan website on August 16, 2026, the listed products included ones at 1,499 yen, 2,000 yen, 2,599 yen and 2,799 yen. The highest listed price was 2,799 yen.

This is only the lineup we could confirm as of August 16, 2026. Rather than treating “Mellojoy’s list price is always in this range” as fixed, check the price on the product page at the time you buy.
The MellojoyJapan website also says it updates product stock daily at noon. The operator, contact details, seller and address can be confirmed in the legally required seller disclosure under Japan’s Specified Commercial Transactions Act.

As for sales channels, a May 2026 @DIME article introduces three official routes for the Japanese market: “TikTok Shop,” “TikTok Live” and “the company’s own site.” Sales methods may change going forward, so at the time of purchase, check the latest guidance from the MellojoyJapan website or official accounts.

When buying a popular item, it’s easy to feel rushed — “if I don’t buy today it’ll be gone,” “it’s now or never.” But precisely because your child wants it, it’s important to make time, once, to check the seller and the price.
What to know about resale prices on marketplace apps
If you couldn’t buy through official sales, you may be tempted to look on resale apps (such as Mercari) or online marketplaces. In fact, you can find used and resold items listed above the official sale price.
That said, you can’t judge “it’s a resale item, so it’s fake” or “the price is high, so it’s genuine.”
On resale apps, the seller is often a private individual, and it can be hard for the buyer to confirm the maker or the purchase route. More than the price, what’s worth confirming is who is selling it, where the item was originally bought, and whether you can check the condition of the product and packaging.
Be especially careful with the reliability of the site itself — not just the product — in cases like “extremely cheap compared with the regular price,” “a limited item, yet huge stock available,” or “no information about who runs the site.”
On August 4, 2026, Japan’s Consumer Affairs Agency issued a warning about fake online shops that pose as selling scarce items such as limited editions at bargain prices. It says consumer affairs centers around the country have received many reports of paying but never receiving the product.

Why can counterfeit squishies be dangerous? Safety points parents should know
In the squishy market, safety warnings have been issued about fake and counterfeit products. But this does not mean that every product from another brand resembling Mellojoy is a “fake.”
On August 5, 2026, the U.S. Consumer Product Safety Commission (CPSC) issued a consumer warning about fake and counterfeit squishy toys.
According to the CPSC, some fake and counterfeit squishies have been found not to meet U.S. safety requirements for children’s toys, including those for water-expanding beads, small parts, lead, and phthalates. It also says some products lack required labeling, such as maker information, a recommended age, and safety warnings.

Comparison table: genuine, resale and counterfeit
It’s hard to judge authenticity completely from images or feel alone. So, drawing on warnings from the CPSC and others, we’ve organized the points for guardians to look at when buying.
| Check item | Product from a verifiable seller | Resale / secondhand item | Clues that suggest a counterfeit |
|---|---|---|---|
| Seller | Company name, contact and return method can be confirmed | May be a private listing; the purchase route needs checking | Seller or contact details are unknown |
| Price | Can be compared with the price on the website | May carry a premium price | Be cautious if the price is far below typical listings |
| Packaging | Brand and product information can be confirmed | Condition needs checking from photos | Typos, rough printing, unnatural logos, etc. |
| Maker / importer information | Confirm on the product or sales page | May need confirming with the seller | No maker or importer information |
| Recommended age / safety labeling | Check the labeling on each product | Confirm from packaging photos, etc. | No recommended age or caution labeling |
| Product condition | Check regularly even after it arrives | For used items, check deterioration especially | Tears, leaks, abnormal stickiness, discoloration, etc. |
The CPSC advises checking whether the seller is trustworthy, whether the price isn’t extremely low, whether the packaging has typos or rough printing, and whether maker/importer information, a recommended age and safety warnings are shown.

How to spot a fake (price, packaging, feel, smell)
There’s information online like “the real one springs back in X seconds” or “this smell means it’s genuine,” but our editorial team could not find primary-source information that can reliably identify whether a Mellojoy is genuine from feel or smell alone.
So we don’t recommend using things like how fast it springs back as a “method for telling genuine from fake.”
On the other hand, for squishies in general, the CPSC lists specific conditions to watch for when buying and using them.
- The maker is unknown
- Required safety information is missing
- It has a strong chemical smell
- It’s oily, or abnormally sticky
- The contents are leaking
- It tears easily
- It has holes or splits
- Discoloration or deterioration is starting
These aren’t items for judging “if one applies, it’s a fake.” They’re safety signs to check before continuing to use it. Don’t keep letting your child use a product with anything abnormal; confirm by contacting the seller or similar.

Trends and safety: how to approach it as a parent
Researching trend toys like this, it’s easy for parents to jump to “It might be dangerous, so we’re not buying it.” But that alone rarely helps a child understand why.
With Mellojoy and beyond, when popularity concentrates and things get hard to find, a child’s attention inevitably turns to the product itself: “my friend has it,” “I can buy it today,” “this site is cheaper.” Instead of dismissing the trend, parents can use the moment to check together who is selling the product and whether the listing looks trustworthy.
The fake online shops that Japan’s Consumer Affairs Agency warned about in August 2026 also exploited situations where consumers judge in a hurry — “scarce item,” “bargain price.” A product your child wants can become a practical chance to learn, together, how to check the seller, the price and the product labeling — which connects not just to choosing toys but to the consumer literacy they’ll need for shopping online from here on.
Ask once, “Why do you want it so much?” and then think together: “If we’re going to buy it, what should we check?” Enjoying a trend and thinking about safety can go together.
From what age can children play with it? Recommended age, choking and microwave heating
For Mellojoy, check the recommended age and caution labeling on each product you buy. As far as our editorial team could confirm on the MellojoyJapan product list and main pages as of August 16, 2026, we could not find a single recommended age common to all products.
So rather than declaring across the board that “Mellojoy is for ages X and up,” it’s appropriate to check the information shown on the product page you’re buying and on the actual packaging.
Japan’s Consumer Affairs Agency also advises checking seller information, safety warnings and cautions, and the recommended age when buying toys online. In Japan, the ST Mark — a Safety Toy mark — is also one indicator of safety when choosing toys.

Also, even a toy bought for an older child needs care about where it’s stored if there are younger siblings at home. The Consumer Affairs Agency urges caution so that infants don’t swallow small parts when an older child’s toy contains them.
(Source: Watch Out for Accidents Where Small Items Like Toys Are Swallowed! | Consumer Affairs Agency)
One more thing to be especially careful about with today’s squishies is heating them, such as in a microwave.
In its August 2026 warning, the CPSC cautions against imitating social-media videos that microwave squishies to inflate them, change their texture or burst them. If a heated toy bursts, hot contents can stick to skin and lead to serious burns.
(Source: Consumer Safety Alert: CPSC Warns Consumers About Fake and Counterfeit Squishy Toys | U.S. Consumer Product Safety Commission)
Beyond the microwave, the CPSC also advises against leaving squishies in places that get hot — in direct sunlight, in a hot car, or near a heater.
Don’t heat squishies on purpose. Don’t leave them where it gets hot. These two points are worth passing on to children in a way that’s easy for them to understand.
Checklist: 4 things to confirm before buying
With Mellojoy and beyond, when buying a squishy you found on social media, confirming at least the following four items makes it easier to decide.
- Seller: Can you confirm the company name, the seller, contact details and the return method?
- Price: Compared with the price on the website, is it unnaturally cheap?
- Packaging: Is there brand labeling, maker/importer information, and no unnatural typos or rough printing?
- Recommended age / cautions: Can you confirm the labeling needed for a child to use it?
After buying, too, check regularly for holes, tears, leaks, abnormal stickiness, strong smell, discoloration and the like.
More than “seeing through perfectly whether it’s genuine,” it’s checking “who you’re buying from,” “what’s labeled,” and “what condition it’s in now” that’s the more practical safety measure at home.
Frequently asked questions (FAQ)
Here we briefly organize the questions guardians often hesitate over before buying Mellojoy.
- Q. From what age can children play with Mellojoy?
- A. As far as our editorial team could confirm, we haven’t found an official recommended age common to all Mellojoy products. Check the recommended age and cautions shown on the product page you’re buying and on the packaging.
- Q. Where can I buy Mellojoy legitimately?
- A. You can buy it on the MellojoyJapan website. As of May 2026, @DIME also introduces three official routes for the Japanese market: TikTok Shop, TikTok Live and the company’s own site. Sales methods may change, so at the time of purchase, check the latest information from the website or official accounts.
- Q. Why can counterfeit squishies be dangerous?
- A. This isn’t limited to Mellojoy, but the CPSC warns that some fake and counterfeit squishies don’t meet safety requirements for children’s toys. It is not a recall of genuine Mellojoy products themselves.
- Q. Is there a risk in buying on resale apps?
- A. Buying through resale apps isn’t necessarily unsafe, but it can be hard to confirm the seller, the item’s purchase route, and the packaging labeling. Don’t judge by price alone; check the product’s condition and the seller information.
- Q. Can you tell a fake by the feel?
- A. Our editorial team couldn’t confirm a reliable test like “the real one springs back in X seconds” from primary sources. Check from multiple pieces of information — the seller, packaging, maker information, recommended age and safety labeling.
- Q. If it has a strong smell or stickiness, is it a fake?
- A. That alone can’t confirm it’s a fake. That said, the CPSC advises stopping use of squishies that have a strong chemical smell, oiliness, abnormal stickiness, leaks, or a state where they tear easily.
- Q. Is it okay to warm a squishy in the microwave?
- A. Please don’t warm it. The CPSC warns that a heated squishy can burst and hot contents can stick to skin, leading to serious burns.
- Q. What should I do if my child may have put the contents in their mouth or swallowed them?
- A. The response differs by product and contents. Keep the product and its contents, confirm what they may have put in their mouth, and seek advice from a medical institution rather than deciding what to do on your own. If your child shows any change in their condition, seek medical advice promptly.
Summary: enjoy the trend, and make safety checks a habit
Mellojoy is a squishy introduced as a new texture-focused item originating in China, which placed #2 in a first-half-2026 trend survey of elementary and middle-school students. For kids, it’s a toy they can enjoy for more than its soft feel — the design, the unboxing, collecting, and sharing with friends all count too.
(Source: First-Half 2026 Trend Ranking | Shinchosha / PR TIMES)
When buying a popular item online, though, it’s important to check the seller, price, maker information, recommended age and safety labeling. Even when using resale or secondhand channels, you can’t judge whether something is genuine by price alone — cheap or expensive.
Also, what the CPSC warned about in August 2026 was fake and counterfeit squishies in general, not a recall of genuine Mellojoy products themselves. Rather than worrying more than necessary, it matters to use the toy while checking its actual condition — tears, leaks, abnormal stickiness, strong smell and the like.
Parents will keep encountering trends and products their children know long before they do.
Not “I don’t know it, so it’s banned,” but “I don’t know it, so let’s check it together.”
Understanding a trend and confirming safety don’t conflict. Listening to your child — “what’s so fun about it?” — while checking together, “then before we buy, let’s look here,” does more than help you choose a toy. It also gives children practice in navigating online shopping and social media more thoughtfully as they grow.
