Japan Weather Overview
Japan 7-Day Forecast (July 13-19, 2026)
While Japan’s rainy season (tsuyu) has ended in Okinawa, Kyushu, and Kansai, it is still underway in Kanto (greater Tokyo) and Tohoku.
This week will generally start with cloudy skies and occasional rain before clearing up for a sunnier weekend. Midweek could bring heavy rain warnings to Northern Japan, while Eastern and Western regions are bracing for intense summer heat.
With temperatures expected to soar above 35°C (95°F) in many areas, staying hydrated and taking breaks in air-conditioned spaces is essential.
Typhoon Information

Currently, Typhoon Bavi is positioned in the East China Sea, southwest of the Korean Peninsula. Although it has weakened, it is projected to curve sharply northeast over the next 48 hours. There is a strong possibility that it will pass over Hokkaido on July 15.
Based on this, coastal areas along the Japan Sea may see rough seas, higher winds, and storm surge. Please keep a close eye on local forecasts, prioritize your safety, and check with your hotel or transport providers before heading to the beach or exploring the coast.
Japan's typhoon season runs from May through October, with most activity from July to September. During a typhoon, transit delays and cancellations can be expected. Be sure to stay updated on the latest weather and flight information. For real-time updates on railways and airports, visit LIVE JAPAN's transport information page.

What to Do in July
July in Japan marks the end of the rainy season and the arrival of true summer, bringing hot, sunny days and the sound of buzzing cicadas. It's the perfect time to experience traditional summer festivals (matsuri), with major events like Kyoto's famous Gion Matsuri and Osaka's Tenjin Matsuri taking center stage. July also kicks off the spectacular fireworks (hanabi) season, with massive displays lighting up the night skies across the country.
Looking to beat the heat? Head north to Hokkaido to see stunning lavender fields in full bloom, or hit the beautiful white-sand beaches of Okinawa. For adventurers, the official Mt. Fuji climbing season opens in early July. Whenever you need to cool down, be sure to try seasonal summer treats like fluffy kakigori (shaved ice), chilled somen noodles, and refreshing slices of watermelon.

City-Specific 7-Day Forecasts (July 13-19, 2026)
Tokyo

Expect a mostly overcast week with brief early sunshine. Daytime highs will peak in the mid-30s before cooling to the upper 20s by the weekend, with nights staying warm around 24°C to 26°C. Keep a compact umbrella handy, as rain chances climb to 40% later in the week. Pack breathable short-sleeve tops, lightweight linen bottoms, and water-resistant walking shoes.

Sapporo
The week begins with sun and clouds before showers arrive midweek, raising rain chances to 60% due to the influence of Typhoon Bavi. Fortunately, skies are anticipated to clear beautifully in time for the weekend. Expect daytime highs to briefly spike to 32°C before settling around 29°C, with mild nights around 21°C to 22°C.
Sendai
Cloudy skies and a few sunny breaks will give way to unsettled, rainy weather by midweek. Temperatures will start hot in the low 30s before cooling comfortably into the upper 20s, with nights resting between 22°C and 24°C. Pack short-sleeve tops, cropped linen trousers, water-resistant shoes, and a travel umbrella.
Osaka
Look forward to a pleasant mix of sunshine and clouds. Rain is unlikely, but the heat will be intense, with highs reaching a sizzling 36°C and warm nights in the mid to high 20s. Stay cool in lightweight tops, loose linen bottoms, and comfortable walking shoes. Bring sunglasses and a small umbrella just in case.
Fukuoka
Bright skies will transition to a steady mix of sun and clouds. The weather will remain mostly dry and consistently hot, with daytime highs hitting 34°C to 35°C before nights cool slightly to 24°C later in the week. Pack cotton tees, breathable shorts, walking sandals, and sun protection, plus a compact umbrella.
Naha
Enjoy a beautiful stretch of sunshine and light clouds ideal for island exploration. Temperatures will hold steady and tropical throughout the week with only a slight chance of rain toward the weekend. Pack your favorite breathable summer wear, comfortable sandals, a wide-brimmed hat, and polarized sunglasses to shield yourself from the brilliant Okinawan sun.
Seasonal Tips & Current Vibe
- Tip 1: Prepare for Intense Heat and Humidity July brings the end of the rainy season and the start of true Japanese summer, with temperatures often climbing past 30°C (86°F) and high humidity. Pack lightweight, breathable clothing, a sun hat, and comfortable walking shoes. Be sure to drink plenty of water, carry a hand fan or portable fan, and take frequent breaks in air-conditioned spaces to beat the heat.
- Tip 2: Embrace the Summer Festival Season July is the ultimate month for traditional summer festivals (matsuri) and spectacular fireworks displays (hanabi). Don't miss major events like Kyoto's Gion Matsuri or Osaka's Tenjin Matsuri. It’s the perfect excuse to rent a yukata (light cotton kimono) and enjoy the lively atmosphere, traditional dances, and delicious street food stalls.
- Tip 3: Book Ahead for Peak Summer Travel With the official start of the Mt. Fuji climbing season and Japanese schools going on summer break late in the month, domestic travel significantly picks up in July. Be sure to reserve your accommodations, tours, and bullet train tickets well in advance, especially if you're heading to popular summer retreats like Furano in Hokkaido or the beaches of Okinawa.
