Whether you’re off to Japan for the cherry blossoms or the ski slopes, there’s a better option than paying $10 a day for roaming on a slower network. Over a month, that’s up to $310 in extra charges.

With TravelKon, you can download and install the latest eSIMs in seconds. Enjoy completely unlimited data and super-fast local speeds for as little as $2.71 a day with a 31-day eSIM.

Enjoy truly limitless, blazing-fast data with KDDI

For one of the best connectivity experiences in Japan, consider a local KDDI eSIM. Once downloaded, you’ll browse like a local with truly unlimited data – no caps or throttling.

Explore Japan by the seasons

Not visiting during Cherry Blossom season? Japan transforms beautifully throughout the year, each offering a unique charm and reason to visit:

  • Spring (March to May): A pastel dream of cherry blossoms and mild temperatures. Hanami (flower viewing) is a beloved tradition, especially in Kyoto and Tokyo. A must-visit for those who love picturesque landscapes and vibrant festivals.
  • Summer (June to August): A mix of humid heat and lively energy. Traditional summer festivals and mountain escapes make this an exciting time to explore. Perfect for those seeking adventure in the countryside or cultural immersion.
  • Autumn (September to November): A fiery canvas of red and gold foliage. Cooler weather makes sightseeing comfortable, while seasonal treats like roasted sweet potatoes and chestnuts add to the experience. Ideal for nature lovers and photographers – see our previous trips to the Kyushu region and the Ehime Prefecture.
  • Winter (December to February): A serene, snow-draped wonderland in the north, while Tokyo and Kyoto remain crisp yet inviting. Skiing in Hokkaido, relaxing in steamy onsens, and enjoying festive illuminations make winter enchanting. A dream for winter sports enthusiasts and onsen lovers.

Whenever you go to Japan, there’s a TravelKon eSIM ready to keep you connected.

Save money on multi-region eSIMs before you travel

If your travels take you to multiple countries before or after Japan, why not consider a TravelKon multi-region eSIM that works seamlessly across different countries?

You’ll only need the one eSIM to enjoy up to 5G data speeds across Asia, including at common transit airports such as Singapore. Prices start from $19 for 3GB of data to use over 30 days, before any discounts.
