eSIM Travel Tips for Japan
Set up your eSIM before your long India-Japan flight
Flights from Delhi or Mumbai to Tokyo take 8 to 9 hours. Install your HelloRoam eSIM at home before departure. Enable data when you land at Narita or Haneda and you are instantly connected for Google Maps, Japan Travel by NAVITIME, and hotel navigation.
Download Hyperdia or Google Maps for train navigation
Japan's rail network is complex but very punctual. Google Maps and Japan Travel by NAVITIME work well for routing on the JR Pass network, Tokyo Metro, and Shinkansen. With your HelloRoam eSIM, you can check real-time train updates on the go.
Cash is still king in Japan
Japan is more cash-dependent than India or most Asian countries. Your HelloRoam eSIM helps you use Google Maps to find the nearest 7-Eleven or Japan Post ATM, which accept international cards. Plan ahead for cash withdrawals.
Keep your Indian SIM for family calls
Keep your Jio or Airtel SIM active in slot 2 on your dual SIM phone. Use HelloRoam as the data line for Japan. You stay reachable on your Indian number while enjoying fast Japanese 5G data for tourism.
Rural mountains and small towns have weaker signal
Japan's major cities and Shinkansen routes have excellent coverage. Rural mountain areas, small farming villages in Tohoku, and parts of Shikoku can have limited signal. Download offline maps before heading into mountain regions.
Mobile networks in Japan: what Indian travellers need to know
Japan's major carriers include NTT Docomo, SoftBank, au (KDDI), and Rakuten Mobile. HelloRoam connects on KDDI/au and NTT Docomo. NTT Docomo is traditionally known for broad rural reach, and all four operators report 99%+ population coverage. KDDI/au is strong in urban areas. Both provide 4G LTE on routes where 5G is not yet available. Coverage and speed depend on the local network.

Best time to visit Japan from India
Japan is a year-round destination with distinct seasons. Cherry blossom season (late March to early May) is the most sought-after time, especially for Indian couples and families. Autumn (October to November) has brilliant foliage. Summers are hot and humid. Winters are cold but ski resorts in Hokkaido and Nagano are excellent. Indian tourists often visit during Diwali long weekends and December school holidays. The Golden Week period in late April to early May is crowded and expensive.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
