Ryohin Keikaku Co., Ltd. (Bunkyo-ku, Tokyo / President and Representative Director: Satoshi Shimizu), which operates Muji, will sequentially launch the 'Rechargeable Clip Fan that can be used freestanding,' which offers three ways to use it as an item to spend a comfortable hot summer, on Wednesday, April 8th, and the 'Stainless Steel Vacuum Double-Walled Insulated Tumbler,' which keeps drinks cold for a long time, from Wednesday, April 22nd, at Muji stores nationwide and online stores.
Ryohin Keikaku aims to create a 'pleasant life and society' by providing products and services that enrich daily life, based on the value of 'simplicity that does not feel inferior to luxury.'
In recent years, as summer temperatures continue to rise, interest in 'heatstroke prevention' and other 'extreme heat countermeasures' has increased, and the demand for ideas and items to spend time comfortably not only outdoors but also at home is expanding.
This season, we have already launched the 'Cool Cotton' series of bedding and cushions made of 100% cotton that achieve contact cooling, and the 'Heat-Resistant Glass Container that can be used in the microwave with the lid on,' which allows microwave cooking without fire and can be used as tableware to brighten up summer dining. We offer a lineup of seasonal limited-edition items to comfortably get through the hot summer, using natural materials, naturally derived ingredients, and functional materials. This time, we are launching a small fan that can be used indoors or outdoors, and an insulated tumbler that allows you to enjoy cold drinks.
● Rechargeable Clip Fan that can be used freestanding
With three installation methods – freestanding, clipping, or hanging with a carabiner (hook) – it can be easily used not only indoors in bedrooms and kitchens, but also outdoors on parasol handles, stroller handles, tent hooks, and more. The airflow can be switched in four stages, and it comes with a 15-minute/30-minute OFF timer, making it suitable for use before sleep or for short periods. It adopts USB Type-C charging.



● Stainless Steel Vacuum Double-Walled Insulated Tumbler
It adopts a vacuum double-walled structure that resists condensation and keeps drinks cold for a long time. The inside is ceramic-coated to suppress metallic odors and allow you to enjoy the original aroma of your drink. Additionally, the tumbler's rim is thinly finished, providing a smooth and pleasant drinking experience.



Furthermore, the 'Insulated Bottle Holder for PET Bottles that can be carried cold' has had its handle specifications reviewed and will be sequentially released from Wednesday, April 15th.
● Insulated Bottle Holder for PET Bottles that can be carried cold
It features a vacuum-insulated structure that prevents condensation. The cover can be rotated to adjust the height to fit the PET bottle. The shape of the handle has been improved to be movable, allowing it to be stored compactly without being bulky. It is now also compatible with 600ml square-shaped PET bottles.



In addition, the 'Cool Series,' including the popular 'Cool Body Mist Extra Cool' from last year, will also be released as a seasonal limited edition from Wednesday, April 8th.
● Cool Series (Body Mist, Clothing Mist, Rinse-in Shampoo, Body Soap)
These are 100% naturally derived* care products for a comfortable summer. They contain menthol as a cooling ingredient. A convenient 'portable size' has been newly added to the 'Cool Body Mist Extra Cool' and 'Cool Mist for Clothes' for use on the go.
*Includes chemically reacted components of natural ingredients



The 'Cool Cotton' series of bedding, rugs, and cushions with contact cooling properties, launched in February this year, is also on sale.
● 'Cool Cotton' Series (Bedding, Rugs, Cushions)
By suppressing fuzz on the fabric surface and finishing it smoothly, heat transfer upon skin contact is promoted, enhancing contact cooling properties, making a cool touch possible with 100% cotton. The fabric achieves both the natural, gentle feel of cotton and a cool, refreshing sensation. In addition to bedding that can be used comfortably during hot summer nights, cushions and rugs for relaxing in the living room are also available.
