Though ranma (transom panels) originally hail from Kyoto, as they became more and more popular among everyday people they started to spread to Osaka, a city where the lumber trade flourished. Over time, ranma techniques were developed and refined to better respond to the exacting demands made by Shitennoji Temple, Shinto shrines within the prefecture, and other clients. Western Japan in particular is noted for the use of Japanese cedar and cypress in carved chokoku-ranma, osa-ranma done in vertical slates, and sukashibori-ranma with cutaway shapes. In recent years, artisans have taken the initiative in producing ranma for this day and age by making new offerings: condo market-oriented items that are done in the simple designs favored by the younger generation.
