From the brand "CHARM MAKE BODY" developed by iiy Inc., a subsidiary of Four Cs HD Inc. (Location: Chuo-ku, Fukuoka City, President and CEO: Hiroyuki Matsuno, TSE Standard Market Securities Code: 3726), which handles cosmetics and aroma products, we have launched "3D Maternity Shorts" designed to address the real concerns from pregnancy to postpartum, on July 1st, 2026 (Wed).

Developer's Discomfort as a "Mother"

The development of this product was triggered by the developer, "Kojimiku, Underwear Expert," herself, who experienced childbirth three years ago.

Despite being an underwear developer, she felt a strong sense of discomfort with existing maternity shorts while experiencing pregnancy.

"As my belly grew, the elastic waistband dug in and became uncomfortable." "My skin became more sensitive, and the seams caused itching and pain." "The size didn't fit, and the pressure around my thighs was bothersome."

Existing shorts couldn't keep up with my changing body day by day... From these real experiences, the project began with the desire to "create the ultimate shorts that fit an ever-growing belly and support the delicate period of before and after childbirth!"

Miku Kojima, also known as "Kojimiku, Underwear Expert"

Meticulously Crafted "3D Design," "Comfort," and "Price"

(1) "3D Design" that Gently Envelops

The most focused aspect was the "3D design" that stretches endlessly to fit the expanding belly and gently envelops it.

Made with a knit structure, there are no seams, achieving an exceptionally comfortable fit that doesn't stress sensitive skin during pregnancy.

We have thoroughly eliminated the stress caused by traditional elastic waistbands and seams, pursuing comfort not only for the abdomen but also for the thigh area, which is prone to size changes.

(2) "Won't Slip Down" Without Elastic

We have completely eliminated the elastic waistband, which can cause tightness and itching as the belly grows.

Our unique 3D knit design securely supports the body, reducing the feeling of constriction.

It snugly envelops the belly as it grows day by day, providing a secure hold.

(3) "Comfortable Leg Openings" Pursuing Stretchability

We pursued comfort not only for the abdomen but also for the thigh area, which is prone to size changes. The leg openings and groin area change as much as the abdomen.

The newly launched "3D Maternity Shorts" focus on the stretch and fit of the leg openings, featuring high elasticity that prevents digging in no matter how much you move.

(4) "High Cost Performance" at 1,980 yen for 3 Pairs

Furthermore, pregnancy is a time when it's difficult to spend money on oneself. With many expenses for childbirth preparations, the developer's wish was "so that mothers don't have to put themselves last," leading to a thorough focus on an accessible price point [3 pairs for 1,980 yen].

The crotch area is 100% cotton for a gentle feel. There are no itchy tags, ensuring a comfortable fit. The knit structure means no seams, reducing itching and pain.

A "New Standard" for Long-Term Use Until Postpartum

It takes several months after childbirth for the enlarged belly to return to its original size. This product is designed for comfortable, long-term use not only during pregnancy but also during the postpartum recovery period.

We aim to make the comfort of this 3D design the "new standard" for maternity shorts, moving away from the current norm of shorts with elastic waistbands and seams! We are launching this product with that vision. We recommend it as an item that can support the minds and bodies of as many mothers as possible.
