Came across a yoga homonym in this article, which turned out to be about western art in Japan. Apparently, in Japanese, yō 洋 means 'Western' as opposed to wa 和, which means 'Japanese'. Yōga is a Western style painting movement in modern Japan and Nihonga is the Japanese equivalent. Thanks Justin B. Stein
