TsukasaJames is a Japanese brand crafting handmade leather guitar straps for rock and metal musicians.

These straps are not made as decoration.
They are made to support the instrument, the sound, and the conviction of the person who carries them.

I was once a composer.
Now, instead of creating sound directly, I create the structure that supports it.

The name TsukasaJames carries my own background and philosophy.
"Tsukasa" is my own name, and in Japanese it conveys the idea of governing structure.
"James" is a name that symbolizes the spirit of metal that has supported me.
As a brand emerging from Japan, I also associate this name with the image of Tokyo's T and Japan's J.
Taken as a whole, the name expresses the idea of supporting through both structure and spirit.

Each strap is handcrafted one by one from cow leather.
Every detail is intentional. Nothing is hidden. Nothing is wasted.
What matters is not only appearance, but also balance, durability, how it fits the body, and whether it can continue to be used on stage.

Each strap carries a name drawn from Japan's feudal era — warriors, weapons, and those who shaped history. These are not decorative references. They reflect the idea that a strap, like armor, is built to be worn in battle.

As the leather is worn over time, it develops character shaped by the person who carries it.
Performance, movement, sweat, and conviction all leave their mark, giving each piece its own unique depth.

TsukasaJames straps are also used on stage by working musicians.
Artist photos and examples of use can be seen on Instagram.

Strap in. Stand apart.
