Japan's foreign-language learning sector saw earnings rise by 0.9% in the 2005 financial year to $5.5bn, according to data gathered by the Yano Research Institute. The moderate growth was mainly due to the expansion of English conversation classes for pre-schoolers and primary school children. This market was estimated to be worth $822m. There was also slight growth in the adult foreign--language teaching sector, which was estimated to be worth $2.3bn. Language schools have expanded their business to include early-morning classes, online teaching as well as Chinese-, Korean- and French-language tuition.
