Greg, we'll be in Osaka for a few days in late Feb/early March. A friend said he heard it's worth going to Shikoku. Being next to Kobe etc. also doesn't hurt. Are you aware of any car rental places that rent fun cars? I found a place which has an old RX7 and Legacy Touring Wagons (which cost more than the RX7 for some reason). If not, I can always just rent a Levorg from Nippon again.
