Driven by this vision, we developed J-TECH EASY CARE (formerly Known as PALPA Premium)—a special yarn made by wrapping cotton around recycled polyester. After three years of development and seven years on the market, it has become our No.1 best-selling fabric, loved for its exceptional comfort and durability. With only cotton touching your skin, it delivers the natural feel of cotton with a refined sheen. Comfort, functionality, and sustainability—this proudly Japan-made shirt offers it all. Experience the difference today.
※ As of January 2025, "PALPA" has been renamed "J-TECH EASY CARE".
Easy Care in 3 Simple Steps
The Easy-Care Shirt is the perfect companion for busy professionals. Simply wash and dry as usual—no extra effort needed. If wrinkles are a concern, a light ironing will do the trick. Enjoy a crisp, clean look effortlessly, without the hassle.
1. Wash Machine washable just like a 100% cotton shirt. Turn inside out and use a laundry net to extend the life of the fabric and buttons. Gentle cycle recommended.
2. Dry After spinning, gently smooth out wrinkles and shape the shirt before hanging. This helps reduce wrinkles as it dries.
3. Wear Wrinkles naturally relax as the fabric dries. Ready to wear the moment you take it off the hanger.
Features of J-TECH EASY CARE
Wrinkle Resistance
Unlike conventional wrinkle-resistant fabrics that rely on surface coatings or resin treatments, J-TECH EASY CARE achieves the same effect through its unique yarn structure.
It has earned a 3.5 rating on the Wash & Wear scale, ensuring long-lasting easy-care performance even after repeated washing.
Quick-Drying
The outer cotton absorbs moisture, while the inner polyester speeds up drying—combining the best of both materials.
As a result, it dries three times faster than a 100% cotton shirt. Even on humid days, during overnight washes, indoor drying, or when damp from sweat or rain, you’ll notice the difference.
Aesthetics
Many wrinkle-resistant shirts can have the shiny appearance typical of synthetic fibers. However, J-TECH EASY CARE features cotton on all parts that touch the skin or are visible on the outside, giving it a natural, refined sheen.
Designed for those who appreciate the comfort and texture of cotton, this easy-care shirt combines both elegance and functionality.
Of course, it retains premium details like Japanese craftsmanship, flat-felled seams, and natural shell buttons.
Environmental Consideration
The core of the yarn is made from recycled PET bottles, while the outer cotton is blended with high-quality Australian cotton. This minimizes the use of bleaching agents (chemicals) and reduces water consumption during washing, achieving "Less Chemical & Less Water."
Additionally, this unique structure allows us to reduce the use of cotton by approximately 30%, making it a more sustainable choice.
Wash & Wear (W&W) Performance
W&W performance refers to the measure of how much wrinkle remains after washing. It indicates the fabric's ability to maintain a smooth, neat appearance with minimal effort post-wash.
Generally, a rating of 2.5 or higher is considered suitable for wearing straight out of the wash. With a 3.5 rating, J-TECH EASY CARE delivers exceptional wrinkle resistance, making it an ideal choice for dress shirts that maintain a sharp, smooth look without extra effort.
Comparison with Standard Wrinkle-Resistant Shirts
100% Cotton × Chemical Treatment
Easy-care properties are added through chemical treatments or resin processing. While labeled as 100% cotton, the fabric tends to feel stiff and has an unnatural texture. Over time, with repeated washing, the wrinkle resistance diminishes, leading to a loss in its long-lasting performance.
100% Polyester
While 100% polyester is easy-care and resistant to wrinkles, it tends to have a sporty look and is less suitable for dress shirts. The fabric lacks the natural feel of cotton and may not provide the refined appearance expected in more formal attire.
Polyester Blend
Easy to maintain while retaining some of cotton’s texture. However, since the polyester fibers are exposed, it has a slightly unnatural appearance and a firmer feel against the skin.
J-TECH Easy Care Yarn
With a polyester core wrapped in cotton, this unique structure offers a natural look and texture while maintaining its wrinkle resistance even after washing. Traditional easy-care shirts often required compromises. But with Kamakura Shirt’s easy-care shirt, you no longer have to sacrifice appearance or functionality.
Yarn Structure of J-Tech Easy Care
Selected for METI’s "Manufacturing Supply Chain Reconstruction Support Project"
With its selection for the Ministry of Economy, Trade, and Industry (METI) initiative, Kamakura Shirts partnered with Unitika Tokiwa Factory in Okayama, known for its top-tier spinning technology in Japan. After three years of development, this collaboration led to the creation of the world’s first J-TECH EASY CARE yarn, which was patented in 2019. This innovative yarn features a recycled polyester core wrapped in cotton, combining Indian premium cotton with high-whiteness Australian luxury cotton in a unique blend, achieving both functionality and a refined look.

It isn't easy to find a fine-gauge cotton sweater, and this one is great. My husband and I (F) both bought multiple sweaters. The fit is relaxed like in the picture, and the waistband allows you to cinch it higher on your hips.
Pros:
- The color for the green and navy sweaters was exactly as shown
- It really does resist odors
Cons:
- The description says to hang dry after washing, in our experience this caused the sweater to stretch. I would suggest drying flat instead.
- There was some variation in the actual size of the garment, the navy we received was smaller than the green.
Wonderful quality as always from Kamakura, with the amazing attention to detail the Vintage Ivy collection is renowned for. A true classic and sure to become a staple of my winter and autumn wardrobe.
I recently picked up the French Work Jacket Kamakura and I'm very impressed. The quality is excellent, and the fit is spot-on—it has that perfect slightly baggy, relaxed workwear silhouette. Highly recommend for a comfortable and stylish jacket!
