DaveSigaty: Murakawa Daisuke is a 6th grade elementary school student in Hyogo-ken, Japan (October 2002). He qualified as professional shodan in the Kansai Ki-in qualifying tournament on October 11, 2002. At the age of 11 years 10 months he is 1 month older than Cho Chikun was when he qualified and is the second-youngest pro ever in modern Japanese Go.
John Fairbairn: I think you'll find he hasn't made it to the record books yet. He has to be approved by the Assessors Panel and his performance as an insei has to be ratified by the Kansai Ki-in Board of Directors. The earliest he can be accepted is 1 November. If he is, at that point he also becomes the youngest Kansai Ki-in pro ever, just ahead of Yuki Satoshi. If there's just a few days delay (i.e.after 4 November) he will be counted as 11 years 11 months. SL fans seem to be Hikaru no Go fans too, so you may wish to know his favourite character is Isumi. I think Murakawa probably already holds the records for youngest ever tsumego problem creator and number created. I think that tells you where his strength lies. It will be good to keep an eye on his rivalry with other local boy Iyama Yuta, who was the first Japanese pro born in the Heisei era. He's at the Nihon Ki-in but in its Kansai Branch. With Hikaru no Go and now real live PRE-teenybopper rivals, Japanese go is back on the way up (recent club figures confirm this).
