Nintendo [J] started Twitter this morning at 9:08 a.m., June 6th (Japan Standard Time).
There were two tweets pointing today’s releases on their website, E3 2011 conference information notice [J] and a bug info of a race game Ridge Racer 3D [J]
The bio section tells “We are going to give notifications and website updates info from Nintendo. We are afraid that we will not answer your inquiries”. It does not sound that this account will tweet anything human-touch.
Nintendo America (@nintendoamerica) has been tweeting actively, but the Japanese HQ were not so keen on social media.
[Update] The 3rd tweet at 1:02 a.m. 7th (JST) was sent by Satoru Iwata, the president of Nintendo (Wikipedia). He wrote,
“Hello, everyone. I am Iwata from Nintendo. I have been in L.A. since Saturday to prepare for E3. I am going to make a few guest tweets per day only during E3. Yoroshiku-onegai-shimasu #Iwata_E3″
