A Traditional Happi, Reimagined

The IKI Happi Jacket & Pants reimagine the happi coat, a haori-style garment beloved in Japan since the Edo period, as a modern everyday set.

#DESIGN PROCESS

Refined Through Prototypes

While preserving the iconic form of the happi coat, we carefully refined the fabric, sleeve length, body width, hem length, and adjustable details through repeated prototypes. The result is a modern happi jacket that feels light, comfortable, and natural in everyday life.

MANUFACTURING PROCESS

Each piece is carefully made in Japan, from fabric selection and sewing to final inspection. Every step is handled with attention to comfort, durability, and the quality needed for a garment you can enjoy for years.
