This page counts CS2 community servers from the Steam list that stand in Japan, by the IP address of the machine. It is the location of the server, not of its players: many communities rent machines in another country, often in Germany, France or the Netherlands, where hosting is cheap and the ping is fine for half of Europe. Valve matchmaking servers are not in the Steam list, so Premier and Competitive games in this country are not here. And the time of day matters a lot: in the morning a country can have a few hundred players, in the evening tens of thousands.
Over the last 30 days servers in Japan had 20 real players at any moment on average - 0% of everyone on CS2 community servers, #42 of 84 countries. Right now 3 people play on 2 servers there, mostly deathmatch and zombie. The maps with the most players at the moment: de_mirage, ze_hazard_escape_p. The busiest time is Saturday around 13:00 UTC, the quietest Tuesday around 23:00 UTC.
