Japan is poised to celebrate the Imperial succession and the start of a new era on May 1 with a festive extra-long 10-day Golden Week from April 27 through May 6.

The string of consecutive holidays, at first glance, appears to be a miniature spring break for children out of school and a summer and winter vacation merged into one for employees who get permission to go.

More people will be traveling, eating and shopping during the break, which is expected to benefit businesses. But it is also expected to be a headache for traders in Japan who are concerned the prolonged shutdown of Japan's financial markets will unsettle the yen.
