The Hinoki Project began in 2000 at Prof. Kikuko Nishina's lab at the Tokyo Institute of Technology's International Student Center as a collaboration among specialists in language education, linguistics, and computer science. The project develops reading and writing assistance systems for learners of Japanese. Asunaro supports multilingual reading and sentence-structure exploration; Natsume searches collocations in large corpora; Nutmeg assists revision of academic writing; and Natane provides access to an error-annotated learner corpus.
