Iki no Hakatoko no Sho

Iki no Hakatoko no Sho (伊吉博徳書) is a historical Japanese record written by Iki no Hakatoko. Composed late in the 7th century, the record is primarily known for being used as a reference in the composition of Nihon Shoki as well as for being the oldest Japanese travel record. It is no longer extant.
