"Kuchiina," who knows Isetan Shinjuku Store, Men's Building inside and out, selects the must-have outerwear for autumn and winter.

Finally, the air feels like autumn and winter, making it the perfect season for layering knits and shirts. In this edition of "Kuchiina," we've carefully selected outerwear and blousons from six brands that are not just for warmth, but the centerpiece of your outfit. Our focus is on lightweight leather jackets, sophisticated shearling coats, and coats that showcase their silhouettes. We'll introduce this wide range of options, available only Isetan Shinjuku Store, Men's Building , along with the appeal of each brand.

1. ARMA Lightweight and on-trend. Three must-have styles from this popular leather brand.

ARMA is a leatherwear brand from Amsterdam, Netherlands. Its biggest appeal lies in its ability to offer high quality at an accessible price, thanks to its own factory.

As a brand that originally enjoyed strong support from women, it offers a wide variety of models despite being a leatherwear brand. It's not just about the typical "masculine leather"; the balance of being light, soft, and easy to wear fits perfectly with today's adult style. It's a popular brand with many repeat customers at Isetan Shinjuku Store, Men's Building , and it expands the range of leatherwear options available.

• ARMA leather blouson "KALE" 132,000 yen
  □Isetan Shinjuku Store, Men's Building, 5th Floor, Men's Tailored Clothing

This short, slightly relaxed blouson-style jacket is made from goat suede and is a best-selling model that pairs well with knitwear.


A leather shirt incorporating Western shirt-style details. It's a versatile piece that can be easily worn over a t-shirt or sweater.



While sharing a similar feel to "DEX," it features a more A-line, relaxed silhouette. It's pocketless for a simple, easy-to-wear look.

Inaba: ARMA is a brand that very clearly embodies the current trends in leather wear. They offer a wide range of styles, from traditional, heavy blousons to lighter pieces that can be worn like a shirt. The appeal of Isetan Shinjuku Store, Men's Building , is that you can compare these current trends in leather wear all within one brand.

Kucchi: Each of the three models has a different silhouette and color, so the impression changes quite a bit when you actually wear them. I hope you'll choose one while considering the overall balance, whether you want to pair it with a knit or wear it over a cut-and-sew top.

2. A new proposition: high-quality leather shirts tailored by LES LESTON , a shirt maker.

LES LESTON is an Osaka-based dress shirt brand. They have handled numerous custom orders and have dedicated themselves to creating shirts that perfectly suit the Japanese physique.

The leather shirts made by LES LESTON are not just leather outerwear, but "leather shirts made with serious dedication by a shirt maker." They are made using 0.6mm thick calfskin, and the finest parts are carefully selected and hand-cut for each shirt.

One of the highlights is how dress shirt-derived sewing techniques, such as the "flat-felled seam" which encloses the seam allowance and creates a beautiful finish on the reverse side, and the "triple-fold hem" which involves folding the edge of the fabric three times and sewing it, are applied to leather. This is a garment that embodies the brand's unique style, blending the presence of leather with the delicate craftsmanship of a shirt.

• LES LESTON calfskin shirt: 165,000 yen

With its slightly A-line silhouette, it looks natural whether paired with wide-leg pants or worn with a coat. Its appeal lies in its lightness, allowing it to be worn like a shirt despite being made of leather.



Inaba: LES LESTON is a brand with a strong background in shirt making. Even though this leather shirt uses leather, the concept is still fundamentally that of a shirt. The details of the stitching and pattern clearly show the techniques that the brand has accumulated over the years.

Kucchi: Rather than seeing it as leather, I'd like people to see it first as a "high-quality shirt." It's easy to throw on, and it develops character the more you wear it. You can wear it casually with wide-leg pants, or layer a coat over it for a more sophisticated look.

3. BARACUTA classic "G9" jacket in leather. A standout piece that sets it apart from the norm.

BARACUTA is a leading British brand. Among its products, the "G9" is known as a masterpiece that can be considered the prototype of the swing top.

While retaining iconic details such as the "Fraser Tartan Check," the "Dog Ear Collar" with its distinctive dog-ear-like shape that can be folded and fastened at the collar tips, and the "Umbrella Yoke" with its double-layered construction on the back, this time we introduce a model made of leather. It's a classic, but the change in material creates a completely different impact and a sense of exclusivity.

Isetan Shinjuku Store, Men's Building , offers a wide selection of G9 jackets, including the standard "G9," but the leather version, in particular, will appear fresh even to those who are already familiar with the classic.

• BARACUTA Leather Blouson "G9" (Cowhide) ¥198,000
  □Isetan Shinjuku Store, Men's Building, 5th Floor, Men's Tailored Clothing

This jacket features a firm leather texture and a distinctive sheen. It's a leather outer garment that gains character the more you wear it, making it a truly impressive piece. Because it's leather, we recommend wearing it a little oversized. Going up one size will give it a more relaxed, outerwear-like fit and a more imposing presence.





The "G9" model is also available in goat suede. Compared to the cowhide model, it has a softer feel and the elegance unique to suede.


Inaba : While many brands offer leather swing-top style jackets, BARACUTA is truly the originator. The fact that this brand makes the leather "G9" jacket gives it a certain appeal. It's recommended for those who want to enjoy a classic style in a more refined way.

Kucchi: It looks great paired with checked pants, and I'd like people who already own a "G9" to try it out too.

4. Alta Cluna Mouton: Lightweight and sophisticated luxury that redefines the concept of Mouton.

ALTACRUNA is an Italian leatherwear brand. They also handle OEM production for numerous luxury brands and have a strong reputation for their use of high-quality leather and sheepskin.

Sheepskin is often perceived as a strong, hard material, but AltaCruna's sheepskin is finely textured and soft, and the tailoring is very smart. The appeal of AltaCruna lies in its sophisticated appearance that is luxurious yet does not appear excessively heavy.






The quality of the materials, the pattern design, and the lightness when worn—all of these elements come together to create a sophisticated, urban-style shearling blouson for adults. While retaining the distinctive presence of shearling, the superior quality of the material and the compact silhouette allow for a stylish look.

Inaba: Altacruna excels in both material quality and pattern design. Despite being made of sheepskin, the shoulder area feels light, making it less heavy when worn. This is something you'll really understand once you actually try it on.

Kucchi: Some people have the impression that sheepskin looks too strong, but this is very elegant. The pile is straight, and the touch is smooth. I want people to first appreciate the quality of the material, and then look at the beauty of the tailoring.

5. LUTAYS Simple yet beautiful. A new coat embodying French elegance.

LUTAYS a brand committed to French craftsmanship and embodying French elegance, has long been a popular choice at Isetan Shinjuku Store, Men's Building .
Rather than relying on flashy designs, LUTAYS clothing leaves a lasting impression through the beauty of its materials, patterns, and silhouettes. It possesses that kind of refined French elegance.

The new "ALLURE" model, which we're introducing today, is a new addition to the collection this season. The name is a French word meaning "elegant" or "graceful," and the coat also draws inspiration from the rounded form of classic French cars, giving it a double meaning.

Made from wool melton, this simple, knee-length coat features a minimalist design with minimal embellishments on the front. The pockets are positioned along the side seams, giving the overall look a clean and streamlined appearance.

On the other hand, the back features deep inverted pleats. From the front, it looks neat and simple, while the back view has movement and elegance, allowing you to enjoy the beautiful silhouette that is characteristic of LUTAYS .

• LUTAYS coat "ALLURE" (deerskin collar) 770,000 yen
  □Isetan Shinjuku Store, Men's Building, 5th Floor, Men's Tailored Clothing

Some models feature a deerskin collar. While the price is higher than the standard model, it offers the presence and unique exclusivity that only French craftsmanship can provide.


Inaba: I think LUTAYS is a brand whose quality shines through the simplicity it offers. Because there are no unnecessary designs, the lines, materials, and tailoring are all directly apparent. The first thing a customer said when they tried it on was, "It's beautiful," and that word is perfectly fitting for this coat.

Kuchimoto: At first glance, it looks very simple, but once you wear it, you can appreciate the rounded silhouette and the beauty of the back view. It leaves a lasting impression despite not having a large design. I would definitely recommend this coat to anyone looking for a coat they can cherish for a long time.

6. TOHNAI "Rustling, fluffy" is the mood right now. A light hooded coat.

TOHNAI is a brand that originally started with a coat collection. Their strong commitment to coats is evident in their material selection and silhouettes, which reflect the brand's unique style.

The item we're introducing today is a hooded coat, which could be considered the brand's signature piece. It's made from black felted material and features a soft, brushed texture.

• 

• TOHNAI coat "WOOL NYLON/PARKA COAT" 165,000 yen
  □Isetan Shinjuku Store, Men's Building, 5th Floor, Men's Tailored Clothing

Despite being a long coat, it's lightweight and has a relaxed silhouette, making it easy to wear. The rich texture of the material prevents it from looking too heavy, even in black, adding depth to your outfit.



Inaba: The current trend in casual wear is towards materials that are crisp yet light and soft. This coat is made from a material that perfectly embodies that trend. It has a modern feel, but the construction as a coat is solid, which is typical of TOHNAI .

Kucchi: You might think plastic buttons would work to give it a lighter feel, but they've used genuine buffalo horn buttons. Plus, it's fully lined, so it's easy to put on. It looks relaxed, but the details show that it's well-made and suitable for adults.
