Heatwave in Japan: Sun Returns as Cities Soar to 33°C

Heatwave in Japan: Sun Returns as Cities Soar to 33°C

General

Sunny skies spread across Kanto, Tokai, and Kansai as temperatures climb above 30°C. Learn key Japanese weather terms and heatstroke warnings.

On Friday the 19th, clear skies are expected to spread mainly across the Kanto, Tokai, and Kinki regions, with strong sunlight beating down throughout the day.

According to the 予想 (yosō, forecast), 最高気温 (saikō kion, daily high temperature) will climb to 33°C in Nagoya City and 32°C in Osaka. In areas experiencing a 梅雨の中休み (tsuyu no nakayasumi, a break during the rainy season), caution against 熱中症 (necchūshō, heatstroke) is advised.

Sunny Skies Centered Around Kanto, Tokai, and Kinki

The forecast says that 関東や東海、近畿を中心に (Kantō ya Tōkai, Kinki o chūshin ni)—“mainly centered around the Kanto, Tokai, and Kinki regions”—there will be 晴れ間 (harema, sunny spells or breaks in the clouds).

The expression 〜を中心に (~ o chūshin ni) means “centered around” or “mainly in.” You’ll hear it often in weather reports and news broadcasts. It highlights the main focus area while leaving open the possibility that other regions may also be affected.

With strong 日差し (hizashi, sunlight) that will 照り付ける (teritsukeru, blaze or beat down), the day is expected to feel intensely hot despite it being the rainy season.

Temperatures Rising in Major Cities

The daily 最高気温 (saikō kion) is forecast to reach:

  • 33°C in Nagoya
  • 32°C in Osaka

The report uses the common forecast ending 〜でしょう (~ deshō), which means “probably” or “likely.” In weather news, this softens the statement slightly, signaling a professional prediction rather than absolute certainty.

For example:

  • 強い日差しが照り付けるでしょう。 Tsuyoi hizashi ga teritsukeru deshō. Strong sunlight will probably beat down.

You’ll frequently hear 〜でしょう in formal contexts like news reports and weather forecasts.

A Break in the Rainy Season

Japan’s rainy season, known as 梅雨 (tsuyu), usually brings persistent clouds and steady rain in early summer. However, there are periods called 梅雨の中休み (tsuyu no nakayasumi), literally “a break in the middle of the rainy season.”

These breaks can bring sudden sunshine and rising temperatures. Because people may not expect extreme heat during the rainy season, warnings about 熱中症 (necchūshō, heatstroke) are especially important.

Even without midsummer temperatures, strong 日差し and high humidity can increase the risk of heat-related illness.
