Top Music Festivals You Can’t Miss

Summer Sonic

Looking for one of the biggest music events in Japan this summer? Don’t miss Summer Sonic 2025, which is held between August 16th and 17th in Tokyo and Osaka. This two-day festival brings together some of the world’s hottest artists and Japan’s top performers. The Osaka event will occur at Expo ’70 Commemorative Park, while Tokyo’s concerts will be at the Zozo Marine Stadium and Makuhari Messe Convention Center. 

This year’s lineup includes famous international artists such as Alicia Keys, Fall Out Boy, YungBlud, Camila Cabello, Katseye, and more! The stages are split between Osaka and Tokyo, with Tokyo having six main stages and Osaka having five. In addition to these stages, there are two extra events: Sonicmania and midnight. Sonicmania is the warm-up party for Summer Sonic, which takes place the night before at Makuhari Messe. 

Fuji Rock

If you love festivals with fantastic music and stunning mountain views, don’t miss Fuji Rock 2025! This legendary three-day event will take place from July 25th to 27th at Naeba Ski Resort in Niigata, one of Japan’s biggest and most beloved music festivals. Around 100,000 music fans attend this major three-day event every year. 

This year’s lineup is packed with global superstars like Vampire Weekend, Vulfpeck, and Fredagain, alongside Japanese favorites such as Vaundy, Radwimps, and Creepy Nuts. With over 100 acts performing across iconic stages like the Green Stage and Red Marquee, there’s plenty to discover, whether you’re into rock, indie, electronic, or something in between.

Experience Nagashi Somen During Summer in Japan!

Nagashi somen, or “flowing noodles,” is a fun and refreshing way to enjoy somen noodles in summer. Thin noodles are sent down a long bamboo slide with cold running water. As the noodles flow down the bamboo slide, you try to catch them with chopsticks, then dip them in the sauce before eating. It’s like a game and a meal in one, making it perfect for hot days! 

One of the most famous places to try nagashi somen is Kibune, a peaceful village in the mountains just outside of Kyoto. At a popular restaurant called Hirobun, you can sit by a clear mountain stream and catch noodles as they flow through the bamboo. The cool air and sound of the water make it a relaxing and memorable experience. Reservations for Hirobun aren’t available, so you should arrive early to secure a spot. Sets start from 2000 yen (13 USD).

Enjoy a Beach Barbecue Party This Summer!

A beach BBQ in Japan is a fun and memorable summer activity, perfect for groups of friends or family. However, not all beaches have designated BBQ areas, so it’s essential to check online reviews or official websites beforehand to see if it’s allowed. If permitted, most beaches follow a “BYO” style, bring your own grill, food, and drinks. Some beaches may have food stalls selling BBQ sets, but these can be limited.

For those who prefer convenience, some restaurants near the beach offer BBQ plans that include food and all-you-can-drink options. A popular choice is THE BBQ BEACH, a chain with stylish setups across Japan, including a popular location in Odaiba, Tokyo. These offer a more relaxed experience where everything is prepared for you, just reserve in advance, show up, and enjoy grilling by the sea. Whether DIY or full-service, beach BBQs are a great way to enjoy Japan’s coastal scenery and summer vibes.

Cool down with Kakigori

One fun and refreshing activity during summer in Japan is to try kakigori! Kakigori is a Japanese shaved ice dessert topped with sweet syrups and other delicious toppings. Typical flavors include strawberry, matcha, melon, and lemon, often with extras like condensed milk, mochi, red bean paste, or fruit. You can enjoy this sweet treat at many cafes across Japan, especially during the hot summer months. It’s also a popular treat at summer festivals, where you’ll see colorful stalls selling it to happy crowds.

Explore Japan’s Mountains During this Summer in Japan!

Mountain climbing is a great way to enjoy summer in Japan and escape the heat! Higher up, the air is cooler, and the views are amazing. Mt. Fuji is the most popular climb, especially in summer, but it gets crowded, and mountain huts must be booked early. You can take multiple trails, but if you’re a beginner, sticking to the Yoshida route is recommended. 

Hakuba Valley in Nagano is a fantastic option if you want something more relaxed. With beautiful trails, fresh mountain air, and fewer crowds, it’s perfect for beginners and experienced hikers alike. Whether you’re chasing a sunrise or just want an incredible summer adventure, Japan’s mountains won’t disappoint.

Why should you spend this summer in Japan?

Summer in Japan offers a perfect mix of fun, culture, and ways to stay cool. There’s something for everyone from world-famous music festivals like Summer Sonic and Fuji Rock to unique experiences like nagashi somen and refreshing kakigori. Outdoor lovers can enjoy beach barbecues or escape the heat by climbing mountains like Mt. Fuji or hiking in Hakuba Valley.
