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 | 261.4 | 149.6 | 13 |
| Mobile — your own SIM | 54.9 | 14.6 | — |
Do not plan on tethering here. Mobile upload (14.6 Mbps) is far below the fixed line (149.6 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.

Where this listing came from
OpenStreetMap has no record of this place, so its name and location came from Overture. The speed figures above are Ookla open data for the surrounding tiles and do not come from Overture.
