eSIM Travel Tips for Osaka

Osaka is a top Japan destination for Australians
Osaka is one of the most visited Japanese cities for Australians, often combined with Kyoto, Nara, and Tokyo on a Japan itinerary. Qantas and Japan Airlines operate services from Sydney and Melbourne. Activate your HelloRoam Japan eSIM at home before departure. One plan covers Osaka, Kyoto, Tokyo, and all of Japan.
Download Navitime or Google Maps Japan transit before landing
Japan's train and metro network is the most complex in the world. Navitime and Google Maps Japan transit both work excellently with live data from your HelloRoam eSIM. Download offline maps and pre-load your transit IC card app (Suica or ICOCA) before landing at KIX to navigate from the moment you arrive.
Cherry blossom season at Osaka Castle causes congestion
Cherry blossom season in late March and early April at Osaka Castle Park brings enormous crowds. Network congestion near the castle can slow data speeds. Download offline maps before heading to the castle during peak blossom season. Signal returns to normal speeds away from the crowded park.
Universal Studios Japan works best with the official app
Universal Studios Japan (USJ) has indoor and outdoor 4G throughout the park. The official USJ app provides real-time wait times, show schedules, and dining reservations. Download the app and log in before arriving at the park. Peak school holiday days can see some congestion in the busiest ride queues.

The Tenjin Matsuri festival in late July is one of Japan's three great festivals, held along the Okawa River.
