koraiban

Koraiban, also known as ko-riban, is a type of Japanese-style martial art that originated in the 17th century. It is essentially a precursor to Kendo, and is a close-range combat sport that involves the use of a bamboo sword.

Koraiban was mentioned in the historical novel "Hogen Monzui" which was written by Eikyu, in 1693. This novel is one of the most significant sources of information on Koraiban. Although not much is known about the specifics of the martial art itself, several illustrations and wood carvings have been discovered that provide insight into the sport.

In Koraiban, practitioners, known as ribanchi, used curved bamboo swords called "koraiba" which reflect the curved shape of a horseshoe or ribbon. The technique and principles of Koraiban are believed to have influenced the development of later Japanese martial arts.

Historical records are limited on the early history of Koraiban, making it challenging for historians to provide a clear understanding of the sport's origins and refinement. However, the evolution of Koraiban into Kendo is a demonstrated fact.

It's also mentioned in other historical documentation such as Edamori imbayashi, which adds a few details about Koraiban including illustrating the popularity of Koraiban in the late 17th century.
