To the relief of more than 500,000 Japanese fans who have been eagerly awaiting its release, the Japanese translation of the second volume of the best-selling "Harry Potter" book series will hit bookstores nationwide later this week.

The Japanese translation of "Harry Potter and the Chamber of Secrets," written by British author J.K. Rowling, follows "Harry Potter and the Sorcerer's Stone," which has sold more than 800,000 copies in Japan since going on sale late last year.

More than 500,000 reservations have been made for the second volume, according to Tokyo publisher Say-zan-sha Publications Ltd.
