Toyota Motor Corp posted a steeper-than-expected fall in quarterly profits after Japan's biggest quake on record hit output, and lamented that making cars at home was tougher than ever now with disasters compounding the impact of a strong yen.

The world's biggest automaker gave no forecasts for the current year due to the continued disruption to production, but said output would begin recovering as much as two months earlier than it had expected as parts makers come back on line.
