from the 17-9-10 in bottom right hand corner 17 signifies 17th year of the reign of Akihito (current Emperor, spelling may be wrong though )
Welldone, I would never have guessed that....
so
2316 @ 2002/11
8899 @ 2003/05
10124 @ 2003/06 bit close must be when it got repaired
then doing around 1200Km/month
some missing years
43444 @ 2005/09
may be a simple explanation for missing service records like never bother taking book in to be stamped, al least you've got some history it has had 4 services in 40K kms or 27K miles
