Mexico's population was slightly less than Japan's in 2015, with projections suggesting Mexico will soon pass Japan. Current statistics do not indicate much difference in population numbers.Japan's population size can be attributed to high growth rates experienced during the late 19th and early 20th centuries.

Since 2010, Japan has experienced net population loss due to falling birth rates and almost no immigration, despite having one of the highest life expectancies in the world, at 85.00 years as of 2016 (it was 81.25 as of 2006.

Religion in Japan is dominated by Shinto (the ethnic religion of the Japanese people) and by Buddhism. According to surveys carried out in 2006 and 2008, less than 40% of the population of Japan identifies with an organised religion: around 35% are Buddhists, 3% to 4% are members of Shinto sects and derived religions, and from fewer than 1% to 2.3% are Christians.[note 2] In 2009, an official survey showed that over half the Japanese families had a "butsudan" or Buddhist altar in their homes.

In 2011, it was reported that 90% of the Japanese identified as Buddhist or Shinto or a combination of both.

 Japan demographics Population by Immigrants

According to the Japanese immigration centre, the number of foreign residents in Japan has steadily increased, and the number of foreign residents (excluding a small number of illegal immigrants and short-term visitors, such as foreign nationals staying less than 90 days in Japan), exceeded 2.2 million people in 2008.

In 2010, the number of foreigners in Japan was 2,134,151. This includes 209,373 Filipinos, many of whom are married to Japanese nationals, 210,032 Brazilians, the majority possessing some degree of Japanese ancestry, 687,156 Chinese and 565,989 Koreans. Chinese, Filipinos, Koreans, and Brazilians account for about 69.5% of foreign residents in Japan.

The current issue of the shrinking workforce in Japan alongside its aging population have resulted in a recent need to attract foreign labor to the country. Reforms which took effect in 2015 relax visa requirements for "Highly Skilled Foreign Professionals" and create a new type of residence status with an unlimited period of stay.

The number of naturalizations peaked in 2008 at 16,000, declining to over 9,000 in the most recent year for which data are available. Most of the decline is accounted for by a steep reduction in the number of Japan-born Koreans taking Japanese citizenship. Historically the bulk of those taking Japanese citizenship have not been foreign-born immigrants but rather Japanese-born descendants of Koreans and Taiwanese who lost their citizenship in the Japanese Empire in 1947 as part of the American Occupation policy for Japan.
