Interior shop management

Seiichiro Iwamura is an importer and retailer of furniture and interior goods based in Fukuoka and Nagasaki.

Iwamura, a regular user, and a SANGACIO staff member are friends, which is why he has occasionally appeared as an amateur model on SANGACIO's social media. Since then, he has been getting approached by strangers on the street more and more often. Here are some snapshots of Iwamura.

How do you wear sneakers and what do you think about SANGACIO?

I think sneakers look cool when worn in a way that shows off the lines of your legs from the knee down, so I overwhelmingly wear them with shorts.

I usually coordinate it with shorts, but I try to eliminate the street feel as much as possible and enjoy elevating or toning it down with a "dress" feel.

SANGACIO has a strong personality in a good way, so I tend to want to coordinate my clothes with simple colors and patterns, but on the other hand, I sometimes choose bold materials and patterns and match them with sneakers to tie the whole look together.

Today I'm keeping it understated by matching the texture with sneakers, but I like that it can go either way.

QWhere are the shoes made?
ACountry of production: Thailand.
Our products are handmade at our directly managed workshop, “SANGACIO INTERNATIONAL.”

In Japan, the shoe manufacturing process—such as gluing, sole production, sewing, and inspection—is typically divided across multiple factories. To maintain full control over quality, we established our own workshop in Thailand, a hub in Southeast Asia where global sneaker manufacturing equipment and expertise are concentrated.

By managing the entire process in-house between Japan and Thailand—from planning and manufacturing to quality control, import/export, and sales—we are able to provide products of exceptionally high quality.
QCould you please provide instructions on how to care for these shoes?
AFor brushed materials, use a shoe brush. For coated surfaces, wipe with a damp cloth. You may also use commercial shoe cleaners if needed.
QIs it okay to use waterproof spray on these shoes?
AYes, you can. Please use a colorless, transparent spray.
