Kodansha International comes to mind when thinking about quality English translations of Japanese folktales like 'Tsuru no Ongaeshi' (The Crane's Return of a Favor). They've built a solid reputation for preserving cultural nuances while making stories accessible to global readers.
Their bilingual editions often include beautiful illustrations that enhance the reading experience. What stands out is how they maintain the poetic rhythm of the original text without sacrificing clarity. Many educators recommend their versions for classroom use due to the thoughtful annotations and cultural context provided alongside the translation.
