Yoshifumi Inatani, who led the RVT reusable rocket vehicle project in Japan, will participate in a panel discussion at the Personal Spaceflight Symposium later this month in Las Cruces, New Mexico.

I interviewed him back in 2004 but haven't heard much about him since then. Should be interesting to hear what he has to say. (He is mentioned in this Japan Times article from January 2007.)

Googling around a bit, I found a set of slides that he gave at a symposium in May in which he discussed RLV development in general and a specific project involving a small, low operating cost, reusable sounding rocket: A Concept & Readiness to the Reusable Sounding Rocket - Norway-Japan Symposium on Polar, Space and Climate Research - May 29.07 (pdf).
