We measured the real mobile speed in Sapporo Center, from Center, on 22/06/2026. With our eSIM connected to NTT Docomo on 5G, the test shows 189.00 Mbps download, 25.90 Mbps upload. That is fibre-like speeds, measured in real travel conditions.
To put that in context: at 189 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 Sapporo Center, the connection easily handles GPS, video calls, social media, tethering and streaming.
