Mari Yamamoto
Men's Clothing Department, Underwear, Socks, Nightwear, Assistant Buyer
I joined the company in 2016. After working as an assistant buyer for shirts, ties, seasonal accessories, tailored clothing, and leather goods, I assumed my current position in 2025. Lately, I've been focusing on my health, making my own lunches and going to the gym as part of my routine. I strive to keep my life in order.

I like to have multiple copies of my favorite items and continue to use them for a long time.

I was shocked by how comfortable it is to wear. GOOD PEOPLE GOOD STITCHING GOOD PRODUCT

Last summer was so hot that I became obsessed with tank tops, and this is one of the many I bought.
I'd seen this tank top on Instagram and was intrigued by it – it's from GOOD PEOPLE GOOD STITCHING GOOD PRODUCT , an original brand launched by a factory specializing in cut-and-sew garments.

Knowing that they use a special sewing machine to make the seams as thin as possible to bring out the best in the material, and having previously worked in a sewing factory myself, I thought, "I want to try this on," and bought one to try it out.
When I actually tried it on, I was shocked by how comfortable it was. I was surprised that such thin seams could make it so light and stress-free to wear. The 100% cotton light rib material is dry to the touch, soft, and subtly silky. The stitching and fabric are a perfect match, and I think the comfort is even more apparent when worn during the hot summer months.
Before I knew it, I had bought another tank top and three more T-shirts from this brand – it's become one of my favorites! It's also a brand that we've just started carrying in the section I manage this season. We have a variety of men's T-shirts available, so please come and check them out in store.

Experience the new comfort of hemp with this Classics The Small Luxury handkerchief.

Even before I was assigned to the handkerchief department, I always prioritized a "smooth texture" when it came to usability, and I loved using linen handkerchiefs. This one is a slightly smaller-sized hemp handkerchief from CLASSICS the Small Luxury. One day I left home without a handkerchief and bought one in a hurry at the men's department store, but when I used it, I found it to be much better than I expected, and before I knew it, I was using only this one. Since then, I've bought many more.

Some people might associate hemp with a rough texture, but thanks to advancements in yarn, weaving, and finishing techniques, it's now possible to create a smooth and comfortable feel without any roughness. It has a firmer thickness and crispness than linen, yet still possesses a soft touch. I also appreciate that it doesn't take up much space in my pocket and doesn't feel unpleasant when it absorbs moisture after wiping wet hands. This excellent balance of practicality makes it a handkerchief I reach for every day. With a wide variety of weaves and colors available, it's the kind of handkerchief that makes me want to buy more every time I find one I like.
Some variations are also available in the men's department, so we would be delighted if you could come and see them in person at the store.
