Is Shadowing Japanese with transcript more efficient

Web sites like the NHK, iTBS or FNN allow to practice shadowing while reading transcripts. The Nikkei daily podcast - the long version - allows for shadowing with partial transcript support granted you have on hand the corresponding printed newspaper. Nude shadowing - shadowing without text support - may be adequate for alphabetical languages, but I wonder if the same apply with character based languages. The relationship between the written and the spoken discourse at the terminology level is so closely imbricated that shadowing while reading may be more effective and strategically essential to improve in Japanese than plain shadowing for non-native learners of Japanese.
