5G test in Tokyo Harajuku (Japan): real 67 Mbps on NTT Docomo
Tokyo Harajuku: our June 18, 2026 field test using an eSIM connected to NTT Docomo on 5G measured 67.00 Mbps download, 22.40 Mbps upload and 188 ms latency. This proprietary result describes that place and moment; it does not represent all coverage in Japan. The published screenshot, time and protocol allow the measurement to be checked and cited with its context.

We measured the real mobile speed in Tokyo Harajuku, from Harajuku, on 18/06/2026. With our eSIM connected to NTT Docomo on 5G, the test shows 67.00 Mbps download, 22.40 Mbps upload and 188 ms latency. That is very strong 5G, measured in real travel conditions.
To put that in context: at 67 Mbps an offline map downloads in seconds, a video call runs without a stutter and HD video starts instantly. Most travellers use only a fraction of this bandwidth.
In Tokyo Harajuku, the connection easily handles GPS, video calls, social media, tethering and streaming.
