The meeting room Fumio Ohtsubo uses when visiting Tokyo from his Osaka base has a Panasonic television and DVD player in the corner, portable Panasonic telephones, a Panasonic air purifier, Panasonic lights and Panasonic air conditioning. Yet the room itself is traditional. Japanese ceramics sit, a little uneasily, alongside French post-impressionists, and the building shows no signs of corporate flashiness.
