My dealer has stock some quality tosai and nisai from Oishi's Oct 06 auction. I would say their kohaku are pretty impressive... fast growing and holds conformation well. Beni has depth and elasticity. However, I've got to point out that their kohaku aren't as big as Hiroshima Sakai at the same age from the farm (nisai average 45cm), but their growth catches up when kept at my dealer's pond.
