Increased competition saw premium revenue rise only incrementally at Japan's largest property insurance companies, according to fiscal 2000 earnings reports released Friday.

Pickings were slim in the world's second-largest nonlife insurance market. Insurance giant Tokio Marine & Fire Insurance Co. saw a 1.9 percent rise in net premium income on a parent-only basis, to 1.3 trillion yen in the year ending March 31.

A low-disaster year coupled with cost-cutting helped the company gain 87.5 percent in net profit, up to 86.4 billion yen.
