TOKYO, May 11 (Reuters) - Japan's Nikkei average slipped 1 percent on Tuesday, as euphoria over a $1 trillion package to prevent the spread of Europe's debt crisis dissipated and as Mizuho Financial <8411.T> fell on news of a big share offering.
Sumitomo Mitsui Financial Group <8316.T> also tumbled as its affiliate consumer lender Promise <8574.T> slid after a loss warning and after a report that SMFG was set to raise its share offer limit.
Doubts over Greece's ability to implement debt cuts as well as worries about weakness in the euro have kept Tokyo stocks this week from matching a 4 percent jump for U.S. stocks -- their strongest gain since March 2009. [
] [ ]"Weakness in the euro is weighing on investor confidence. There are concerns whether the crisis plan will really come to fruition because each country still has to discuss it," said Yutaka Miura, a senior technical analyst at Mizuho Securities.
"In today's market environment, there's no buying other than short-covering, and once that comes to a halt, the market gets overwhelmed by profit-taking."
The benchmark Nikkei <
> fell 100.27 points to 10,430.43, after earlier rising as much as 1.1 percent to 10,643.28.The broader Topix <
> fell 1.1 percent to 933.96.Orders for Japanese stocks placed through 10 foreign securities houses before the start of trade on Tuesday showed selling for a fourth straight day. [
]The euro fell 1 percent against the yen to around 118.00 yen <EURJPY=> a day after jumping almost 2 percent against the Japanese currency. Against the dollar, it stood at $1.2730 <EUR=>, down 0.5 percent.
"What the EU did was really huge, but the fact that the euro is still weak despite that large a package shows that this problem has very deep roots," said Masayoshi Okamoto, head of dealing at Jujiya Securities.
"Without more gains in the euro, markets will remain nervous."
MIZUHO DROPS, PROMISE TUMBLES
Mizuho lost 4.1 percent to 164 yen, becoming the most actively traded stock by volume on the main board, after sources told Reuters that it plans to issue about $8.7 billion of shares to meet stricter capital requirements. [
]Mizuho has been under pressure to raise new capital after top lender Mitsubishi UFJ Financial Group <8306.T> raised about $15 billion and third-ranked Sumitomo Mitsui about $20 billion in their two rounds of fundraising between December 2008 and February this year.
Mizuho raised only $5.7 billion in the same period.
Toyota Motor Corp <7203.T>, which announces results later on Tuesday, came under new scrutiny on Monday from the U.S. government, which launched a probe into whether Toyota promptly notified safety regulators about a pickup truck recall for a steering system problem. [
] [ ]Its shares fell 0.6 percent to 3,500 yen.
Investors dumped shares of companies reporting disappointing earnings outlooks.
Shares of Promise Co <8574.T> tumbled 16.6 percent to 720 yen after the consumer lender warned it would likely fall back into the red this year, defying expectations for a small profit in a sign the industry may not be past the worst. [
]Among other big consumer lenders, Acom Co <8572.T> dropped 6.3 percent to 1,303 yen and Takefuji Corp <8564.T> lost 6.2 percent to 336 yen.
Japan Steel Works <5631.T> shed 4.5 percent to 936 yen after it issued an operating profit forecast, 21 percent below the previous year and just under a consensus estimate from Thomson Reuters I/B/E/S.
Food group Ajinomoto <2802.T> fell 3.9 percent to 816 yen after the company estimated its operating profit for this financial year at 57 billion yen, down 11 percent from the previous year and below a consensus of 66.4 billion yen from Thomson Reuters I/B/E/S.
But Sumitomo Heavy Industries <6302.T> jumped 4.2 percent to 595 yen after it said it will make Nihon Spindle <6242.T>, a maker of spindles and rings for spinning machines, a wholly owned subsidiary to seek synergy effects for further business growth.
Shares of Nihon Spindle were untraded due to a glut of buy orders at 210 yen, up more than 30 percent from Monday's close. (Additional reporting by Elaine Lies; Editing by Edwina Gibbs)
