Looking at changes after May 1, 1993, when the highest number of overstayers was recorded, the country (place of origin) of the largest number of overstayers as of May 1, 1993 was Thailand, followed by R.O. Korea, the Philippines, China, and Malaysia. In the ranking as of January 1, 2010, R.O. Korea was top followed by China, the Philippines, China (Taiwan), and Thailand.

The changes in the number of overstayers by nationality (place of origin) were as follows. Although new entries have increased drastically since visa-exemption measures have been implemented for those who intend to engage in activities that can be performed under the status of residence of “Temporary Visitor”, the number of overstayers from R.O. Korea has been consistently decreasing since January 1, 1999. The number of those from Thailand has steadily decreased since May 1, 1993. The number of those from Malaysia and Peru has also seen a decrease due to a measure to promote the acquisition of visas, which was taken on June 1, 1993 and on July 15, 1995 respectively. The number of those from China continued to decrease from 1994 until 2002. Then, it started to increase in 2003 and further increased in 2004, but it has also shown a decreasing trend since 2005. The number of overstayers from the Philippines has been decreasing since 1998, but fluctuated between increasing and decreasing.
