A problem with wigle (and maybe others) it it&#x27;s showing every portable mobile wifi hotspot which are extremely common in Japan. If you&#x27;re trying to find all the places someone who owns that hotspot has been maybe that&#x27;s useful info but usually it&#x27;s not that useful. Zoomed in to the maximum level there&#x27;s so many SSIDs it&#x27;s unreadable.
