**TOBU RAILWAY AWASH WITH SELL ORDERS ON CAPITAL RAISING**

Tobu Railway 9001.T , a Japanese rail operator and property developer, was overwhelmed with sell orders 10.5 per cent below Wednesday's close of 407 yen, after it said it would raise as much as 93.2 billion yen ($1.13 billion) in a share offering to buy back convertible bonds maturing in 2014.

"The impact of the deals may be short-lived, but if there are more financing deals coming out due to a recent recovery in the stock market, further falls are likely," said Yutaka Miura, a senior technical analyst at Mizuho Securities.

Tobu, which is building the 634 metre (2,080 ft) Tokyo Sky Tree broadcasting tower, said it would sell up to 218.5 million new shares including a greenshoe option, potentially boosting the total number of shares outstanding by 25 per cent. 0026 GMT
