There are 3 Japanese 50ks that take place in consecutive weeks during the European Claycourt season. One is on hard and the other two are on grass, not sure if the grass is natural or artificial. But regardless, these provide Kimiko with a great opportunity to A) spend some time in Japan and play a few events in front of her home fans. B) pick up some valuable ranking points C) get some practice on grass prior to the Grass court season and D) Avoid the European red clay, aside from RG and maybe one event the week before.
Kimiko really does need to play these events rather than toiling for weeks on the European red clay. But aside for this adjustment I think sticking with the WTA level events the rest of the year until the post seaon ITFs makes sense.
Its the very thing Tanasugarn does sometimes which we saw work perfectly in 2008 when she won s'Hertogenbosch & made the QF at Wimbledon. Also the same events KDK made her comeback in that same year.
