With the first confirmed case reported in Niigata Prefecture late on Saturday, Japan's infections of A/H1N1 flu have amounted to 378.

The 21-year-old female, who studied in the United States, developed a fever after arriving at the Narita international airport Friday and tested positive for the new H1N1 strain of influenza A, according to Niigata health authorities.

As A/H1N1 flu appears to run out of steam in Japan, Kobe High School and Hyogo High School in the hardest-hit Hyogo Prefecture, with 17 and 43 confirmed cases of the new flu respectively, reopened Saturday and will resume classes on Monday following a two-week closure.

The prefectural authorities said that the move came as no new H1N1 cases have been found at the two schools and Kobe High School and Hyogo High School since May 21 and all those infected with the new flu at the two schools have recovered.

All public high schools in Hyogo Prefecture have thus reopened.
