Jiyuujin Club (Location: Yokohama, Kanagawa Prefecture, Representative: Takahiko So) has launched the new generation cooler gear "Large Capacity Cooler Bag Freeba Cool" for pre-sale on Makuake starting June 27, 2026. This product is designed to protect the freshness of groceries on the way home, driven by the "demand for bulk buying" due to rising prices and the anticipated "nationwide heatwave in 2026."

Within 24 hours of its launch, support purchases exceeded 3 million yen (with the fastest discount return sold out). The item is receiving an exceptional response as a stress-reliever for summer shopping, with comments like "I can buy ice cream and still stop by a cafe on the way home" and "I can buy in bulk at cheaper supermarkets with peace of mind."

Since its launch, we have received feedback such as "I want to use it for bulk summer shopping," "I want to bring home frozen foods and ice cream with peace of mind," and "I was looking for a large-capacity yet lightweight cooler bag."

Summer 2026 is Expected to Be Hot Nationwide. Bringing a New Sense of Security to the "Time" of Bringing Food Home.

A comfortable sense of security for summer shopping.

The Japan Meteorological Agency has announced that temperatures in the summer of 2026 (June-August) are expected to be higher than average nationwide. The probability of temperatures being higher than average is particularly high at 70% for Eastern and Western Japan.

Have you ever felt "I have to go home soon" after buying frozen foods, ice cream, or fresh produce?

On a hot day, the battle against time begins the moment you buy groceries until you get home.

The heat inside your car, hesitation to make detours, anxiety about bringing home ingredients found at tourist spots or roadside stations.

"Freeba Cool" was born to reduce such anxieties on the way home from shopping.

Shop Without Rushing, Enjoy Meals with a Smile

Not just going straight home after buying frozen foods, but also taking a break at a cafe, having a meal with family, or bringing home delicious finds from your travels.

"Freeba Cool" is cooler gear that creates a little extra time during travel by carrying coolness.

Freeba Cool Born from the Voices of 1,411 People from Our Previous Product.

365-Day Usable Cooler Gear to Change Summer Shopping in the Age of Global Warming

Internal test conducted at an ambient temperature of 30°C, simulating peak summer days.

In internal tests conducted in an environment with an ambient temperature of 30°C, simulating harsh midsummer days, with ice placed directly inside the bag, ice was confirmed to remain even after 12 hours.

This cooler design is intended to provide ample time for bringing home frozen foods, ice cream, fresh produce, meat, fish, drinks, and more.

Designed to Block External Heat and Prevent Cold Air from Escaping

[To Media Representatives] We are happy to accept requests for demonstration interviews, such as "comparison experiments of ice melting between general cooler bags and this product" and "actual shopping trips with a detour to a cafe," as well as sample provision to demonstrate the cooling power of this product. Please feel free to contact us.

Our previous product, "365FReeezDesign," received over 12.29 million yen in total support purchases, from 1,411 supporters, and sold over 1,800 units on Makuake.

"Large capacity yet lightweight," "Can safely bring home frozen and refrigerated items," "Folds up when not in use, convenient for car storage."

"Freeba Cool" was developed in response to such feedback.

The outer fabric uses DuPontTM Tyvek® soft type. The 6-layer insulation structure, combining 8mm PE foam, aluminum heat reflection layer, and PEVA, pursues a design that suppresses external heat and prevents cold air from escaping.

Can Be Used Lavishly Like This

Detailed Design You'll Want to Use Every Day

Furthermore, the adoption of a water-stop double zipper and zipper end guard has evolved the design to suppress water ingress and gaps from the opening, trapping cold air. The interior uses PEVA material that is easy to wipe clean of condensation and dirt, and the heat-sealed construction prevents water leakage and drip leakage.

We are committed not only to "cooling power" but also to "large capacity yet lightweight," "ease of daily use," and "a design that you'll want to carry," aiming for a "new standard for cooler bags that can be by your side for daily shopping and long journeys, usable 365 days a year."

Two Large Capacity Sizes Available: 36L for Family Bulk Purchases and 26L for Daily Use.

Two sizes to choose from based on lifestyle and shopping volume.

Bulk purchases filling one shopping basket can fit in this one bag. *For the 36L size.

L Size / Approx. 36L Ideal for weekend bulk shopping, family groceries, roadside stations, direct sales markets, BBQs, and leisure. Can store up to 8 x 2L PET bottles upright.

M Size / Approx. 26L Ideal for regular shopping, for those who prioritize ease of carrying, and for daily use. Can store up to 6 x 2L PET bottles upright.

Easy to carry when going out, and a large capacity cooler bag on the way home.

Compact When Not in Use

Both sizes are large capacity yet foldable when not in use. If you keep one in your car trunk or at home, you can handle sudden bulk purchases or shopping at roadside stations.

From Daily Shopping to Emergencies. Cooler Gear to Keep by Your Side 365 Days a Year.

Cooler Bags Are Now for 365-Day Use

"Freeba Cool" is useful year-round for bulk shopping at supermarkets, roadside stations and direct sales markets, BBQs, picnics, visiting relatives, and long car trips.

Furthermore, by keeping it in your car or at home, it can also be used to temporarily store food in case of a power outage, in conjunction with ice packs.

So that you can use familiar items when you need them.

"Freeba Cool" is cooler gear that accompanies your life, not just in summer, but 365 days a year.

Comment from Takahiko So, Representative of Jiyuujin Club

Many people probably feel "I have to go home soon" when buying frozen foods or ice cream on a hot day.

I myself have experienced giving up on detours on the way home from shopping, or hesitating to bring home ingredients I found while traveling.

With our previous product, we received support from 1,411 people, and many comments regarding cooling power, large capacity, lightness, and ease of folding.

Based on that feedback, we thought, "We want to create a cooler bag that is even more resistant to cold air leakage, easier to use every day, and more desirable to carry," and "Freeba Cool" was born.

"Freeba Cool" aims to slightly reduce the rush on the way home from shopping and create a little extra time during travel. We hope it becomes an item that makes everyone's daily life a little freer.

We are deeply grateful for the many supports we have received since the first day of our launch.
