Wii U error won’t let Japanese users access eShop, firmware update, DQX beta

Some Wii U owners in Japan are having issues launching the eShop and are also unable to apply the latest firmware update. Instead, they’re receiving error code “105-3102”. This also means that it’s impossible to start up Dragon Quest X’s new Wii U beta at the moment.

The issues are caused a program inside the console, Nintendo says, which will soon receive a patch. Users can expect an update sometime this weekend.
