Summer in Japan might not be the ideal time for every traveller. It’s hot, humid, and a bit intense. But let’s be honest, every time I’ve been to Japan, no matter the season, it’s always been an unforgettable experience. And the bonus? Flights are usually cheaper in summer! So if you’re like me and thinking about a summer trip to Japan, this guide’s got you covered.

How Is The Weather During Summer In Japan?

From around late June to August, Japan’s temperatures usually sit between 28°C and 35°C during the day, but it can feel even hotter because of the crazy humidity. I’ve experienced the temperature hitting 37° C. Whether it’s summer in Osaka or summer in Tokyo, it feels just as intense, especially in August.

There’s also the rainy season (called tsuyu) that kicks in around June, which means you’ll get warm, sticky days with sudden downpours. It’s not all-day rain, more like tropical bursts. The sun can be intense too. I always make sure I’ve got sun cream, a hat, and one of those handheld fans. I bet an umbrella will become your best mate too.

To be fair, it can be tiring walking around in that heat, especially in crowded cities. I found myself ducking into convenience stores or cafés every hour just to cool off.

What Cities Can Be Visited During Summer In Japan?

Alright, the weather might be on the intense side, but summer is still a brilliant time to soak up both Japan’s natural beauty and cultural charm. Each city offers something a bit different, and all well worth a visit. There will be loads of festivals, fireworks, cold noodles, and icy drinks everywhere. Here are some of recommended best place to visit in Japan during summer:

Tokyo – Non-stop city buzz, epic festivals like the Sumidagawa Fireworks, and loads of summer shopping deals. Joining one day trip from Tokyo in summer is also a fun idea!
Kyoto – Home to the famous Gion Matsuri, peaceful temples, and stunning seasonal kaiseki dishes.
Osaka – Street food heaven in Dotonbori, and Universal Studios Japan is a blast in the summer.
Sapporo (Hokkaido) – If you’re after cooler weather, head north. The flower fields in Furano and Biei are absolutely gorgeous.

Naha (Okinawa) – Think tropical beaches, clear blue water, and that laid-back island vibe. Also, don’t miss snorkeling and diving with shark whales while in Okinawa.
Nagano – Ideal for escaping the heat, with mountain retreats, hiking trails, and crisp fresh air. Evergreen Hakuba summer camp is an activity you can miss!
Karuizawa – A classy summer hideaway just outside Tokyo with cooler temps and boutique charm.

What To Pack During Summer In Japan?

Packing smart is key to enjoying your trip, especially with Japan’s hot and humid summer. Here’s what I always make sure to bring:

Light, breathable clothing – Stick to natural fabrics like linen or cotton. Loose-fitting clothes are a lifesaver when it’s humid.
Sun protection – Pack sunscreen, a good pair of sunglasses, and a wide-brimmed hat or cap.
Umbrella or light raincoat – A small travel umbrella (with UV if available) or a packable raincoat will come in handy.
Comfortable walking shoes – You’ll be walking loads, so bringing lightweight trainers or walking sandals are perfect.
Cooling towel or handheld fan – A cooling towel around your neck or a portable handheld fan can make a huge difference when you're out in the heat. You can buy it at any convenient store in Japan.
Mosquito repellent – Especially important if you’re heading to rural areas, parks, or anywhere near water. Japan’s mosquitoes can be quite active in summer evenings.
Swimwear – If you’re planning to visit beaches in Okinawa, go to onsen resorts with pools, or even just want to cool off at your hotel, bring a swimsuit just in case.

Where To Stay During Summer In Japan?

Hotels in Tokyo – Stay in Shinjuku or Shibuya for easy access to public transport, shopping, and nightlife. You’ll find everything from budget hostels to high-rise hotels with city views.
Hotels in Kyoto – Book a stay in Gion or Higashiyama if you’re after a more traditional feel. Think charming machiya-style guesthouses, boutique hotels, and cosy ryokans tucked in old streets.
Hotels at Mountain towns – For a cool summer escape, stay in a ryokan or mountain lodge in places like Hakone or Takayama. Expect scenic views, hot springs, and peaceful surroundings.
Hotels in Sapporo – The Odori area is a great base for exploring flower fields nearby. There’s a good mix of business hotels, modern apartments, and family-friendly stays.
Hotels in Okinawa – Head to beach resorts in Nago, Onna, or Ishigaki for sea views, outdoor pools, and tropical vibes. Perfect if you’re planning a laid-back beach holiday.

For a more seasonal experience, consider staying near summer festivals or close to nature. My tip? You can book all kinds of hotels across Japan, in any city or district, on Traveloka. It’s super easy to use and often offers some of the best deals around.
