Japan's Rainy Season 2025: Status, Forecasts, and Travel Tips

Today, July 18, the Japan Meteorological Agency announced that the rainy season is considered to have ended in the Kanto Koshin, Hokuriku, and southern Tohoku regions. The rainy season ended one day earlier than normal in the Kanto Koshin region, five days earlier than normal in the Hokuriku region, and six days earlier than normal in the southern Tohoku region.

---------------

Today, on the 18th, the Japan Meteorological Agency announced that "the rainy season seems to be over in Kanto Koshin, Hokuriku, and southern Tohoku". It is the end of the rainy season in Kanto Koshin, which is 1 day earlier than normal, 5 days earlier than normal in Hokuriku, and 6 days earlier than normal in southern Tohoku.

---------------

The Japan Meteorological Agency declared that the rainy season ended in western Japan on June 27th. This is the earliest end of the rainy season in the history of Japanese meteorological observations. It looks like this year's hot summer will be long in Japan. Please be careful.

End of the Rainy Season in Okinawa and Amami

On June 19, 2025, the Japan Meteorological Agency announced that the Amami region in Kagoshima Prefecture has reached the end of its rainy season ("tsuyu"). This marks an end to the rainy period about 10 days earlier than average and 3 days earlier than last year. The rainy season in Amami began around May 19, so this year’s tsuyu lasted about one month. Okinawa also exited the rainy season at roughly the same time.

The early end of the rainy season is due to a strong Pacific high-pressure system covering Japan. The weather forecast for the next week predicts mostly sunny days for Okinawa and Amami. Typically, these regions see the end of the rainy season in late June, but this year, it has arrived a bit earlier than usual.

Upcoming Weather Trends

• From late June, sunny and hot days are expected nationwide due to the Pacific high. Extreme heat is likely.
• Just before and after the end of the rainy season, humid air from the south may cause localized heavy rain and thunderstorms. Stay alert.
• At the end of the rainy season, there is a higher risk of torrential rainfall and "linear rainbands," which can cause landslides and river flooding. Be cautious.

Travel Tips for International Visitors

1. Traveling During the Rainy Season:
   • Okinawa and Amami have already exited the rainy season, so now is the perfect time to enjoy beaches and marine activities.
   • For Honshu (especially Kansai, Kanto, and Tohoku), the rainy season is expected to end from early to mid-July. After that, summer will be in full swing.
   • During the rainy season, sudden heavy rain and high humidity are common even in urban areas. Always carry a compact umbrella or raincoat, and check the weather forecast regularly.
2. Heat and Heatstroke Prevention:
   • After the rainy season ends, temperatures will rise rapidly. Stay hydrated, take breaks in the shade, and wear hats or sunglasses to avoid heatstroke.
3. Disaster Preparedness:
   • At the end of the rainy season and just after, the risk of heavy rain, landslides, and river flooding increases. If visiting mountainous or riverside areas, pay attention to the latest weather and evacuation information from local authorities.
4. Flexible Travel Planning:
   • Weather can change suddenly, so have backup plans for indoor activities such as museums or shopping malls in case of rain.

Summary

• In 2025, Okinawa and Amami exited the rainy season earlier than usual, with sunny and hot weather continuing.
• For the rest of Japan, the rainy season is expected to end from early to mid-July, with rainfall amounts around or slightly above average, and the season itself slightly shorter than usual.
• After the rainy season, be prepared for extreme heat and potential heavy rain disasters.
• Travelers should check the latest weather information and plan flexibly according to the weather conditions.

Japan’s rainy season varies greatly by region. For a safe and comfortable trip, make use of weather forecasts and local information, and always stay alert to weather-related risks.

享受北海道無梅雨季節：國際旅客完整活動指南

今天（7 月 18 日），日本氣象廳宣布，關東甲信地區、北陸地區和東北南部地區的雨季被認為已經結束。關東甲信地區的雨季比正常時間早一天結束，北陸地區比正常時間早五天結束，南東北地區比正常時間早六天結束。

北海道是日本最北端的島嶼，獨特地避開了影響日本大部分地區從六月到七月的梅雨季節（梅雨）。在此期間，遊客可以享受涼爽舒適的天氣，同時探索充滿活力的節慶、茂盛的花田和文化活動。本指南重點介紹國際旅客體驗北海道夏日魅力的主要景點和實用建議。

六月上旬亮點：YOSAKOI索朗節

歷史根源與文化融合

每年六月上旬在札幌舉行的YOSAKOI索朗節，融合了高知縣活潑的Yosakoi節與北海道傳統的索朗節漁民民謠。起源於1992年，這個節慶最初只有10支隊伍和1,000名參與者，但現已發展成吸引超過200萬遊客的重大活動。其創立理念——「城市就是我們的舞台！日本將會改變」——反映了透過動態表演復興在地文化的使命。

體驗節慶

節慶的主舞台設在大通公園，各隊伍展現結合傳統動作與現代風格的高能量舞蹈競賽。參與者使用鳴子響板，原先設計用來驅趕稻田中的鳥類，為他們的表演增添節奏強度。旅客可以在Waodori廣場參加工作坊，或觀看週日夜晚的壓軸表演，各隊伍展示精心編排的演出。在札幌溫和的初夏氣候下（平均15-20°C），戶外享受相較於日本本土潮濕的梅雨季輕鬆許多。

六月中旬文化與自然景點

上之國夷王山祭

夷王山祭（6月14-15日）在上之國町慶祝該地區的歷史，由兒童領導火炬遊行登上夷王山到夷王山神社。主要活動包括民謠表演、當地美食攤位和箏（日本豎琴）音樂會，提供了解北海道鄉村傳統的機會。

津別九輪草週

從6月14-22日，津別Nonno森林的九輪草週節慶展示30萬株粉紅色九輪草（日本櫻草）在濕地中綻放。遊客可以沿著木製步道漫步，同時了解森林療法——一種將沈浸自然與減輕壓力聯繫起來的實踐。該地點的偏遠位置（距離津別市中心24公里）確保了在北海道荒野中的寧靜沈浸。

六月下旬至七月：海岸美食與花田

小樽祝津鯡魚·御館祭

六月下旬，小樽的鯡魚·御館祭慶祝鯡魚，這種魚類是北海道海洋歷史的核心。旅客在海濱攤位烤新鮮鯡魚（每條300日圓），同時探索歷史運河和玻璃吹製工作坊。這個活動強調了北海道作為海鮮和手工藝中心的身份。

十勝和富良野的花田

從六月下旬到七月，十勝的日出公園和富良野的富田農場盛開著薰衣草、罌粟花和向日葵。上富良野薰衣草節（7月12-21日）每晚點亮花田，創造出完美攝影的超現實景觀。附近的滝野鈴蘭丘陵國營公園在400公頃的花海中提供健行步道。

旅客實用建議

氣候與服裝

北海道六月至七月的溫度範圍從10°C（早晨）到25°C（下午）。請準備輕便的層次穿搭、防水外套，以及參加戶外活動時的防蟲劑。

交通

在YOSAKOI等重大節慶期間，由於道路封閉，札幌的地鐵系統（例如，南北線到大通站）比開車更有效率。對於津別等鄉村地區，租車提供靈活性，儘管前往Nonno森林的接駁巴士在工作日運行。

文化禮儀

尊重當地習俗：拍攝表演者前請先徵求同意，妥善處理垃圾，避免在活動場館附近的住宅區大聲喧嘩。

結論

北海道無梅雨的夏季結合了文化活力和自然壯麗，為日本本土的梅雨季提供了避暑勝地。從札幌令人興奮的舞蹈到富良野薰衣草香氣瀰漫的夜晚，這座島嶼邀請旅客發現其傳統與寧靜的獨特融合。透過提前規劃和擁抱當地習俗，遊客可以完全沈浸在北海道的季節魔力中。

Enjoying Hokkaido’s Rain-Free Season: A Comprehensive Event Guide for International Travelers

Today, July 18, the Japan Meteorological Agency announced that the rainy season is considered to have ended in the Kanto Koshin, Hokuriku, and southern Tohoku regions. The rainy season ended one day earlier than normal in the Kanto Koshin region, five days earlier than normal in the Hokuriku region, and six days earlier than normal in the southern Tohoku region.

Hokkaido, Japan’s northernmost island, is uniquely free from the rainy season (tsuyu) that affects much of the country from June to July. During this period, visitors can enjoy cool, comfortable weather while exploring vibrant festivals, lush flower fields, and cultural events. This guide highlights key attractions and practical tips for international travelers seeking to experience Hokkaido’s summer charm.

Early June Highlight: YOSAKOI Soran Festival

Historical Roots and Cultural Fusion

Held annually in early June in Sapporo, the YOSAKOI Soran Festival blends Kochi Prefecture’s lively Yosakoi Festival with Hokkaido’s traditional Soran Bushi fishing folk songs17. Originating in 1992, the festival began with just 10 teams and 1,000 participants but has grown into a major event attracting over 2 million visitors17. Its founding philosophy—“The city is our stage! Japan will change”—reflects its mission to revitalize local culture through dynamic performances7.

Experiencing the Festival

The festival’s main stage at Odori Park features teams competing in high-energy dances combining traditional movements with modern flair1. Participants use naruko clappers, originally designed to scare birds from rice fields, adding rhythmic intensity to their routines1. Travelers can join workshops at Waodori Square or watch the grand finale on Sunday night, where teams showcase meticulously choreographed performances1. With Sapporo’s mild early-summer climate (averaging 15–20°C), outdoor enjoyment is effortless compared to mainland Japan’s humid tsuyu7.

Mid-June Cultural and Natural Attractions

Iōyama Festival in Kaminokuni

The Iōyama Festival (June 14–15) in Kaminokuni-cho celebrates the region’s history with a torchlight procession led by children ascending Mount Iō to Iōyama Shrine25. The main event includes folk song performances, local food stalls, and a koto (harp) concert, offering insights into Hokkaido’s rural traditions25.

Kurinso Week in Tsubetsu

From June 14–22, the Kurinso Week festival in Tsubetsu’s Nonno Forest showcases 300,000 pink kurinso (Japanese primroses) blooming across wetlands3. Visitors can stroll wooden pathways while learning about forest therapy—a practice linking nature immersion to reduced stress3. The site’s remote location (24 km from central Tsubetsu) ensures tranquil immersion in Hokkaido’s wilderness3.

Late June to July: Coastal Delights and Flower Fields

Otaru Nishin-Otate Festival

In late June, Otaru’s Nishin-Otate Festival celebrates herring, a fish central to Hokkaido’s maritime history. Travelers grill fresh herring (¥300 each) at waterfront stalls while exploring historic canals and glassblowing workshops4. The event underscores Hokkaido’s identity as a hub of seafood and craftsmanship.

Flower Fields of Tokachi and Furano

From late June to July, Tokachi’s Hinode Park and Furano’s Farm Tomita burst with lavender, poppies, and sunflowers. The Lavender Festa Kamifurano (July 12–21) illuminates fields nightly, creating surreal landscapes perfect for photography6. Nearby, the Takino Suzuran Hillside National Park offers hiking trails amid 400 hectares of blooms6.

Practical Tips for Travelers

Climate and Clothing

Hokkaido’s June–July temperatures range from 10°C (mornings) to 25°C (afternoons). Pack light layers, a waterproof jacket, and insect repellent for outdoor events36.

Transportation

During major festivals like YOSAKOI, Sapporo’s subway system (e.g., Namboku Line to Odori Station) is more efficient than driving due to road closures1. For rural areas like Tsubetsu, renting a car provides flexibility, though shuttle buses to Nonno Forest run on weekdays3.

Cultural Etiquette

Respect local customs: ask permission before photographing performers, dispose of trash properly, and avoid loud noises in residential areas near event venues57.

Conclusion

Hokkaido’s rain-free summer combines cultural vibrancy and natural splendor, offering respite from mainland Japan’s tsuyu. From Sapporo’s electrifying dances to Furano’s lavender-scented nights, the island invites travelers to discover its unique blend of tradition and tranquility. By planning ahead and embracing local customs, visitors can fully immerse themselves in Hokkaido’s seasonal magic.
