This jacket is made of soft corduroy material that creates an autumn/winter mood.
The relaxed size and chic coloring give the jacket a calm and relaxed look that can be worn both casually and beautifully.
In addition to the large collar and patch pockets, the direction of the fabric's ridges is deliberately switched horizontally and vertically on the body part to create a jacket with a unique character.
The big silhouette does not choose bottoms, so it looks great just by wearing it. We recommend you to set it up with Koiki Transform Pants 8 Wale Corduroy made of the same material.



This pile weave corduroy fabric is soft to the touch. The wide ridges on the surface of the fabric keep the air inside from escaping, making it a fabric with excellent moisture retention and absorption properties. Black The gray color is a nuanced color that gives a sense of the fall and winter seasons.

I am a designer at Eriko Yamaguchi. I would like to share with you where my inspiration came from and what I am particular about when I am making a product.


The corduroy fabrics we have developed so far have been "9 wale", which has a narrower vertical line, but this time we used "8 wale", which has a slightly thicker vertical line.

Corduroy itself was used in the fall/winter of 2022, and was my personal favorite because it is very easy to use and you don't have to worry about wrinkles, but I think there were many lady-like pieces last year.

This season, when I met the "8wale" material, I got a more robust impression and thought, "I want to make a men's set-up! I thought, "I want to make a men's set-up!
Therefore, the first image sketches I drew were also for men's wear.

I was very particular about this.

The three important points I focused on were "the angle of the collar," "large cuffs," and "pockets that can hold a lot of things.

The collar is neither too large nor too small, and I imagined that it would look good with the first button undone.

The cuffs have two buttons with the ERIKO YAMAGUCHI logo, and the antique-length button corduroy was a perfect match.

The most difficult part was the pockets.
Corduroy is a strong fabric, so even if the pockets are large, the fabric doesn't lose its shape.

So I decided that I would like to go out without a bag and put my wallet and cell phone all in my pockets (even though I am a bag designer ・・・・), so I made the longer jackets with 4 cm gusseted pockets.

It's already really convenient, and the flap allows me to put it in my pockets (laughs).


The color worn with the set-up is gray.
The smoky hue is a recommended color.
