Japanese shares tumble as crude oil extends slide
* BOJ-inspired rally offset by fading hopes of more support steps

The Nikkei stock index skidded 3.1 percent in morning trade, pulling further away from a three-week high touched on Monday.
The broader Topix and the JPX-Nikkei Index 400 both fell 3.3 percent.
