The Japan National Tourism Organization has launched another campaign to lure tourists from Singapore as the number of visitors from the city-state has yet to return to pre-March 11 levels.

JNTO data show that Singaporean visitors dropped almost 37.8 percent in December compared with the year before, even though the month is traditionally the peak season because of Singapore's yearend school holiday.

The total number of tourists from Singapore in 2011 was down 38.5 percent from the record 180,000 in the previous year, dashing the JNTO's hopes of a recovery by the year's end.
