Jackson has performed just 16 dates on her Rock Witchu tour
Janet Jackson's tour of Japan has been postponed, with promoters blaming the global financial crisis.
Japanese concert promoter Kyodo Yokohama said the singer cancelled five concerts due to take place in February.
The 42-year-old Grammy Award winner had planned to perform in several major cities, including Nagoya and Osaka.
Jackson, on her first world tour in nearly seven years, cancelled seven performances in the US in 2008 because of a bout of vertigo.
The gigs in Japan will be rescheduled later this year, with new dates expected to be announced in March.
The star was recently in the UK to support older sister LaToya during her stint in the Celebrity Big Brother house.
