What type of package is it in? The Toshiba data-sheet says
it is a gual-gate GaAs FET in a surface mount package.

Your description sounds more like a TO-50 pill or X type package.
Most Japanese dual-gate FETs in pill packages use the same
pinout as the BF981. The long lead is probably the drain,
although I have seen a few that had a long lead for G1.
