Measured on this block in Jul-Sep 2026 — the ceiling the hotel's WiFi sits under. Shared WiFi, captive portals and per-device caps only make it slower, never faster.

Fixed line vs mobile
| Network | Down | Up | Ping |
|---|---|---|---|
| Fixed broadband — what the WiFi runs on | 274.7 | 255.7 | 16 |
| Mobile — your own SIM | 29.4 | 9.0 | — |
Do not plan on tethering here. Mobile upload (9.0 Mbps) is far below the fixed line (255.7 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.

Outages in Japan

Country- and ISP-level outages, not hotel-level. A national outage takes the hotel with it; the hotel's own router failing will never show here.
