Some universities, libraries and museums in Japan hold Qur'an manuscripts, such as The University of Tokyo, Kyoto University of Foreign Studies, Tenri Central Library and Toyo Bunko (the Oriental Library). The National Museum of Ethnology in Osaka, also, holds several manuscripts of Qur'an, but they are not widely known. The purpose of this essay is to introduce some of the Qur'anic Manuscripts held in this museum. The Qur'anic manuscripts introduced here are as follows; I: part 11 of a 30-part Qur'an in Bihari script with a Persian translation. It includes an endowment text in Persian (probably early 10th century A.H.) II: a Qur'an in Persian Naskh script with beautifully illuminated double spread page containing the first sura and the beginning of the second sura. It has a colophon signed by Muḥammad Muḥsin al-Nayrīzī, dated 1121 A.H. III: two unbound Qur'ans in Sudani script, one of which is kept in a leather bag. Both of them have colorful patterns to mark divisions of the text. IV: a Qur'an from Aceh, Indonesia, with illuminated double spread pages in three places; at the beginning, the middle and the end of the Qur'an. V: two Qur'ans in Ottoman Naskh script produced in accordance with the standardized page-setting of the Ottoman Qur'an in the 18th and 19th centuries. One of them is signed by Ḥasan al-Ḥusni, dated 1279 A.H.
