Travel eSIM Speeds Reach 272 Mbps at Tokyo’s Major Cherry Blossom Viewing Sites
Field tests conducted at prominent cherry blossom viewing locations in Tokyo have demonstrated that travelers utilizing local travel eSIMs can achieve rapid and stable mobile connectivity during Japan’s peak sakura season.
Field tests conducted at prominent cherry blossom viewing locations in Tokyo have demonstrated that travelers utilizing local travel eSIMs can achieve rapid and stable mobile connectivity during Japan’s peak sakura season.
The tests were performed at Ueno Park, Meguro River, and Shinjuku Gyoen National Garden using a local travel eSIM connected to the au mobile network operated by KDDI .
The early-season tests indicated strong mobile performance across all tested locations. Idle latency was recorded at below 40 milliseconds , ensuring responsive network capabilities even in crowded sightseeing areas. The highest download speed was observed at Meguro River , reaching up to 272 Mbps .
Download Speed: Up to 272 Mbps at Meguro River Idle Latency: Below 40 milliseconds Network: Local travel 5G eSIM with an unlimited data plan
The early-season tests indicated strong mobile performance across all tested locations.
The local travel eSIM connects directly to Japan’s domestic network infrastructure, bypassing international roaming routes. This configuration reduces latency and enhances data responsiveness for travelers.
Japan’s cherry blossom season, peaking between late March and early April , is a major tourism event, drawing millions of visitors. The field tests were conducted before the anticipated peak bloom period, expected to see a significant increase in visitor numbers.
Connectivity Lab will continue to monitor mobile network performance at major sakura viewing sites as visitor numbers increase during the peak travel period.
