Coverage in Japan

Subway and underground rail tunnels in Tokyo and Osaka have near-universal LTE/5G coverage, but mountainous rural areas in central Honshu and Hokkaido have significant coverage gaps. Band 11 (1500 MHz) and Band 18/26 (800/850 MHz) are Japan-specific LTE bands often absent from foreign phones, limiting rural and indoor coverage for roaming devices.

Japan travel guide

Enjoy your Japan vacation

Japan is a country of beautiful contradictions — ancient temples tucked between glass-and-steel skyscrapers, bullet trains that run to the second, and ryokan inns where time slows to the rhythm of a tea ceremony. From the neon chaos of Tokyo's Shinjuku to the moss-carpeted paths of Kyoto's Arashiyama bamboo grove, every region delivers its own distinct character. Whether you're chasing cherry blossoms in spring, soaking in an onsen with mountain views, or wandering a lantern-lit festival, Japan rewards every kind of traveller. With a uPhone eSIM active before you land, you'll have instant access to maps, translation apps, and Google Maps on Japan's fast 4G/5G network — no expensive roaming, no airport SIM queues.

Top attractions in Japan

Japan packs an extraordinary range of experiences into a relatively compact archipelago — from World Heritage temple complexes and imperial gardens to volcanic peaks and colourful pop-culture districts. These are the highlights no first-time visitor should miss.

  • Senso-ji Temple, Tokyo — Tokyo's oldest and most iconic temple in the Asakusa district. Visit at dawn before the crowds arrive for an almost meditative experience.
  • Fushimi Inari Shrine, Kyoto — Thousands of vermillion torii gates winding up a forested mountain. Hike past the tourist crowds to the upper trails for sweeping city views.
  • Arashiyama Bamboo Grove, Kyoto — A towering corridor of bamboo that sways and whispers in the wind. Best visited early morning when light filters through the canopy.
  • Hiroshima Peace Memorial Park — A moving and essential site built around the Atomic Bomb Dome, accompanied by a world-class museum that tells the story with unflinching honesty.
  • Mount Fuji & Fuji Five Lakes — Japan's sacred volcano is climbable July–September; the rest of the year, view it from Lake Kawaguchiko for the classic reflection shot.
  • Dotonbori, Osaka — Osaka's famous entertainment canal, lined with giant mechanical crabs, ramen signs, and takoyaki stalls. The beating heart of Japan's food capital.

Popular foods to try in Japan

Japanese cuisine is built on the principle of shokunin — artisan mastery applied to a single dish. From world-renowned sushi to soul-warming ramen, each regional style has been refined over generations. Eating in Japan is one of the great pleasures of any trip.

  • Ramen — Rich pork (tonkotsu), soy (shoyu), or miso-based broth with chewy noodles, chashu pork, soft-boiled egg and nori. Every city has its own style — Hakata, Sapporo, Tokyo all differ dramatically.
  • Sushi & Sashimi — Fresh, pristine, and precise. Try a conveyor-belt kaiten-zushi for casual dining or splurge at an omakase counter where the chef chooses each piece.
  • Takoyaki — Osaka's famous octopus balls: crispy outside, molten inside, topped with bonito flakes, mayo and sweet-savory sauce.
  • Tempura — Light, airy battered seafood and vegetables fried to golden perfection. Best eaten freshly made at a dedicated tempura counter.
  • Yakiniku (BBQ) — Grill your own premium wagyu beef and pork belly over charcoal at the table. An unmissable social dining experience.
  • Matcha everything — Green tea ice cream, matcha lattes, warabi mochi dusted in matcha powder — Japan's obsession with this earthy flavour produces some of the world's best tea-based desserts.

Best time to visit Japan

Spring (late March–early May) is Japan's most iconic season — cherry blossoms (sakura) transform parks and riverbanks into clouds of pink and white. Crowds are heavy but the atmosphere is electric, especially in Kyoto's Maruyama Park and Tokyo's Ueno Park. Book accommodation months in advance.

Autumn (October–November) is equally spectacular: maple foliage (koyo) blazes red and gold across mountain temples and forest parks. Temperatures are crisp and comfortable, and tourist numbers are lower than spring. Nikko, Kyoto's Eikan-do and Hokkaido's Daisetsuzan are prime foliage destinations.

Summer (June–August) is hot and humid, with the rainy season (tsuyu) in June–July. However, summer brings vivid festivals (Gion Matsuri in Kyoto, Awa Odori in Tokushima) and spectacular fireworks displays. Winter (December–February) is cold in Honshu but ideal for skiing in Hokkaido and Nagano, and offers uncrowded visits to temples dusted with snow.

What to pack for your visit to Japan

Japan is exceptionally well-organised and you can buy almost anything on arrival, but a few essentials will make your trip significantly smoother — especially around digital access, payments and cultural etiquette.

  • IC card or cash — Get a Suica or Pasmo card for trains and convenience stores. Many small restaurants, temples and rural vendors are cash-only, so carry some yen.
  • Comfortable walking shoes — You will walk 15,000–20,000 steps per day in cities. Choose shoes that slip on and off easily — you'll remove them frequently at temples and traditional restaurants.
  • Portable umbrella — Japanese convenience stores sell excellent fold-up umbrellas cheaply, but having one avoids the scramble when sudden rain hits.
  • Pocket tissues & hand sanitiser — Public toilets often have no paper towels. Pocket tissues are used everywhere.
  • Layers for variable weather — Even in summer, air conditioning in shops and trains is aggressive. A light cardigan or jacket is always useful.
  • Your uPhone eSIM — Activate before boarding. Japan's 5G network (SoftBank/NTT Docomo) offers blanket urban coverage and strong signal even in temple valleys and mountain towns.

Frequently Asked Questions

Everything you need to know about your Japan eSIM

The facts do not specify coverage in the Seikan Tunnel. In Tokyo and Osaka, subway and underground rail tunnels have near-universal LTE/5G coverage. For this specific tunnel, you should expect possible signal loss, especially if your phone lacks Japan-specific bands like Band 11 or Band 18/26.

This FAQ section is for Japan only. The facts provided do not mention coverage in any other country, including South Korea. You would need to check the separate product page for multi-country or regional eSIMs to confirm whether Japan and South Korea are bundled.

The facts list four operators: NTT Docomo, KDDI (au), SoftBank, and Rakuten Mobile. The specific network your eSIM uses depends on your eSIM provider’s roaming agreements. This page does not state a single default network.

Yes. Band 11 and Band 18/26 are Japan-specific LTE bands often absent from foreign phones. The facts indicate their absence limits rural and indoor coverage. In mountainous rural areas of central Honshu and Hokkaido, where significant coverage gaps already exist, you may experience weaker signal.

The facts provided do not mention any ID registration rules for eSIMs. Japanese law previously required ID for physical SIMs but regulations for eSIMs may differ. For your specific eSIM product, you should check the provider’s purchase flow for any identification steps.
