Where to go and what to do

There is a long list of beaches in Japan to relax in the summer heat.

The cultural events that are organized throughout the country should have a special place on your list of things to do in Japan in August. The Nebuta Festival, for example, starts at the beginning of the month and lasts for six days. Over 20 massive lanterns based on mythical stories are paraded through the city of Aomori. However, if musical events are your cup of tea, the Summer Sonic Festival welcomes travelers with fun, food and rock music on the third weekend of August in Chiba and Osaka.

If you are not in the mood for dancing, make sure that you spend a few days enjoying the beautiful beaches of Japan. Okinawa is the go-to place for the ultimate fun in the sun, and the weather in Japan in August is perfect for a few sunbathing sessions. This island is home to numerous sandy stretches, with Okuma Beach, Emerald Beach, Araha Beach and Sesoko Beach being some of the most popular. If you do not want to contend with crowds, there are plenty more options in the outlying islands. However, if you wish to head to Tokyo and its surroundings, Odaiba is a great choice.

Although few travelers realize it, the city of Tokyo is a superb destination for hiking enthusiasts. Leave behind its streets and head for the trails that scour Mount Fuji to enjoy nature. For an enhanced encounter with the natural world, do not miss out on the nature reserves of Hokkaido, where you can spot a variety of unique plants and animals while hiking in solitude. Home to bears, deers and foxes, Shiretoko National Park is one of the best national parks to visit in the region in August.

August is the perfect time to discover Japan and experience its mix of cultural activities and outdoor explorations. Lose yourself in its megacities and explore the range of entertainment options available. Else, head for sunny beach towns and picture-postcard mountain villages to enjoy nature and experience local traditions. If you are still undecided, feel free to reach out to our local travel experts and book your customized trip to Japan.
