Diehard Hanshin Tigers fans already know their baseball team's fight song by heart and thanks to a new dictionary, they can now find out what the words mean.

Already a hit with fans, the new Tigers dictionary went on sale earlier this month, featuring the anthem on an "obi," a strip of paper looped around a book, and definitions for the words and many others inside.

Tokyo-based Sanseido Co. teamed with the Hyogo-based Hanshin Tigers for the publication, which comes near the beginning of the new academic year, the best season for selling dictionaries.

The 1,760-page dictionary was designed and edited based on the Sanseido Japanese dictionary.

The new style of dictionary, dedicated to all the fanatic fans of the team, was launched with the aim of reversing shrinking demand caused by the declining birthrate and the aging population as well as the rise in Internet searches.

Clad in the baseball team’s uniform featuring the Tigers’ primary logo--a yellow tiger head inside a black-and-red circle on black-and-white stripes--the dictionary jacket was handsomely bounded.

A photo of Hanshin Koshien Stadium, the home of the Tigers, is featured in the front of the dictionary. From its packed stands, the team’s anthem, "Rokko Oroshi,” reverberates throughout the game.

With the lyrics of the anthem featured on the obi, enthusiastic fans may recall memorable plays and highlights while singing the song--and searching for words and terms, some of which can only be found in this dictionary.

For example, on its page to explain how terms are spelled in the Roman alphabet, words related to the Hanshin Tigers such as “Hansin,” “ganbare" (hang in there) and “nekketu" (hot-blooded) are included as a reference.

As an example for the usage of “Hanshin,” a part of the team’s anthem "Rokko Oroshi” was cited, which says,“(Hanshin) Tigers, hurrah, hurrah, hurrah!” printed in red, which vastly differs from the original Sanseido Japanese dictionary that reads: “(Hanshin) industrial zone.”

There are two other words that cite original examples of their usage related to the baseball team. But it remains a “secret as to which words they are,” providing readers the opportunity to “enjoy finding them as a treasure hunt,” according to a Sanseido official.

“We want those who usually don’t look in a dictionary and those who have been away from printed books to open it and realize the joy and fun of reading the dictionary,” said the official.

When the company preannounced the sale of the dictionary in January, it was swamped with orders for the first edition of 20,000 copies. That led the company to decide to do a second printing even before it went on sale.

The dictionary is priced at 3,000 yen ($28), excluding tax.
