'Submerged forest' captivates tourists at lake in Japan's Gunma Prefecture
Lake Okushima in Gunma Prefecture is a dam reservoir with a circumference of about 4 kilometers. Each spring, as melted snow flows into the lake, trees on the shore and shallows are submerged, making it appear like the trees are growing out of the lake.
This enchanting scene is visible for only two months.
Visitors are captivated by the contrast of the green forest and the lake's bright blue water, known as "Shima Blue."
A couple from Saitama Prefecture said the yellow, green and blue colors are very beautiful. They added that next time they want to ride a canoe to get a closer look.
An official of the dam management office says water discharge began on Thursday and people can enjoy the view until next week when the water level drops.

Japan's nationwide average temperature for July hits record high
Japan's weather officials say the country had its hottest July on record this year. The Japan Meteorological Agency says the nationwide average temperature for the month was a record 2.89 degrees Celsius higher than usual. It says the country faced "abnormally high" temperatures. The agency says the average is the highest for July since such data began to be collected in 1898 and broke previous records for the third straight year. Officials say this year's deviation from normal is much larger than past figures. On Wednesday, a temperature of 41.2 degrees was logged in Hyogo Prefecture's Tamba City, the highest ever observed in the country. On July 24, the mercury rose to nearly 40 degrees in some parts of the northern prefecture of Hokkaido. The average temperature in July was 6.3 degrees higher than normal in Oumu Town, Hokkaido, 4.8 degrees higher in Aomori City, northern Japan, and 2.7 degrees higher in central Tokyo. Meanwhile, the country had less rain in July. Precipitation was only 13 percent of the average amount on the Sea of Japan side of the Tohoku region and just 8 percent in the Hokuriku region and Niigata Prefecture. The figures are record lows since such data began to be compiled in 1946. An agency official said the wide northward meandering of westerly winds is a cause of abnormal high temperatures and less rain. The official also said severe heat and less precipitation are expected to continue in August.

Japan Logs Hottest July for 3rd Year in Row
News from Japan Society Aug 1, 2025 21:45 (JST) Tokyo, Aug. 1 (Jiji Press)--Japan's average temperature in July hit a record high for the third consecutive year, the Japan Meteorological Agency said Friday. This July's average temperature was 2.89 degrees Celsius higher than the 30-year average for the month. The positive deviation was the largest since records began in 1898. As the average temperature in June also hit a new record high this year, the average summer temperature from June to August is "likely to rewrite the record, too," said Yoshinori Oikawa, head of the agency's Center for Information on Climate Extremes. Last year, the country experienced the hottest summer for the second straight year. Meanwhile, the amount of rainfall in July was 13 pct lower than average along the Sea of Japan coast of the Tohoku northeastern region and 8 pct lower along that of the Hokuriku central region. Both areas saw record-low rainfall. [Copyright The Jiji Press, Ltd.] Jiji Press
