With the first case confirmed in Yamanashi Prefecture Sunday, Japan's patients of A/H1N1 flu amounted to 379, Xinhua reported.
According to the prefectural government, a woman was confirmed to be infected with the new flu after coming back from the United States.
It was the one and only case of the new flu reported in Japan on Sunday after a 21-year-old female, who studied in the United States, was confirmed by Niigata health authorities Saturday to be infected with the new H1N1 strain of influenza A.
As A/H1N1 flu was running 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.
