It could be going dormant. My willow-leaf would drop its leaves every
winter; I'd cut back on water until new leaves started to emerge, usually in
late February. Your tree might have taken the change in environment as a
cue to go dormant.

Of course, it could be a root problem. Either way, cut back on water and
watch the tree carefully. As soon as temperatures get toasty, put the tree
outdoors. Figs may be "indoor" bonsai, but nothing beats the great
outdoors.

Won't it be susceptible to disease outside?
