Why Onishi Exists

Onishi was born from a simple idea: underwear should make you look and feel sexy—without loud logos or distractions. Most men’s underwear is over-branded, uncomfortable, and designed to promote the brand, not the wearer. We wanted something different.

That’s why Onishi was created—to bring you sleek, minimal underwear that feels like an extension of you. No big logos. No distractions. Just the perfect fit.

At Onishi, we believe underwear should be about you, not the brand. That’s why our pieces are non-branded, timeless, and designed for confidence, comfort, and self-expression—without the unnecessary noise.

The Fabric: Why Modal?

Luxuriously soft, ultra-breathable, and sustainable—just perfect for underwear.

Modal is a high-end fabric made from beech tree fibers, offering an unbelievably soft touch with exceptional breathability. Unlike cotton, Modal production uses 10-20x less water, making it a more sustainable choice without compromising on comfort.

Care Instructions
