Japan's embassy in China is urging its citizens to pay more attention to their safety while in the neighboring country as sensitive anniversaries and territorial tensions might exacerbate anti-Japanese sentiments.

The embassy notice cites the anniversary of the end of World War II on Aug. 15 and two other dates in September. It said some incidents of harassment of Japanese citizens in China have been reported.

Japan's foreign minister summoned China's ambassador this week and lodged a protest over the increased number of Chinese vessels in waters near East China Sea islands controlled by Japan but claimed by China.

Beijing has also expressed concern over planned visits by members of Prime Minister Shinzo Abe's Cabinet to Tokyo's Yasukuni Shrine, which honors war criminals among the war dead.
