     There is one foreign product the Japanese are buying faster than others and its popularity has caused an

uneasy feeling among many Japanese.

     That product is foreign words.

     Gairaigo-words that come from outside-have been part of the Japanese language for centuries. Mostly

borrowed from English and Chinese, these terms are often changed into forms no longer understood by native

speakers.

     But in the last few years the trickle (涓涓细流) of foreign words has become a flood, and people fear the

increasing use of foreign words is making it hard for the Japanese to understand each other and could lead to

many people forgetting the good qualities of traditional (传统的) Japanese.

     "The popularity of foreign words is part of the Japanese interest in anything new, says university lecturer

and writer Takashi Saito. "By using a foreign word you can make a subject seem new, which makes it easier

for the media (媒体) to pick up."

     "Experts (专家) often study abroad and use English terms when they speak with people in their own fields.

Those terms are then included in government white papers," said Muturo Kai, president of the National

Language Research Institute. "Foreign words find their way easily into announcements made to the general

public, when they should really be explained in Japanese."

     Against the flow of new words, many Japanese are turning back to the study of their own language. Saito's

Japanese to Be Read Aloud is one of many language books that are now flying off booksellers shelves.

     "We were expecting to sell the books to young people," said the writer. "but it turns out they are more

popular with the older generation, who seem uneasy about the future of Japanese."
