Tourism in Japan is a major industry and contributor to the Japanese economy. In 2024, the total number of domestic tourists in Japan, including day trips, reached 540 million, while the number of international tourists visiting Japan was 36.87 million. Total tourism consumption within Japan amounted to 34.3 trillion yen ($237 billion), accounting for 5.6% of the country’s GDP of 609 trillion yen ($4,208 billion). Of this amount, Japanese tourists spent 26.2 trillion yen ($181 billion) domestically, while foreign tourists contributed 8.1 trillion yen ($56 billion). From a statistical perspective, spending by international tourists in Japan is classified as exports. As a result, the inbound tourism industry ranks as the second-largest export industry after the automobile industry, which recorded 17.7 trillion yen ($122 billion) in export value. In that year (2024), domestic tourism spending by Japanese nationals, the number of international tourists, and the total tourism spending by international visitors all reached record highs.
 

The revolution of air travel between 1945 and 1969 contributed greatly to tourism in the United States. In that quarter century, commercial aviation evolved from 28-passenger airliners flying at less than 200 mph (320 km/h) to 150-passenger jetliners cruising continents at 600 mph (970 km/h).During this time, air travel in the U.S. evolved from a novelty into a routine for business travelers and vacationers alike. Rapid developments in aviation technology, economic prosperity in the United States and the demand for air travel all contributed to the early beginnings of commercial aviation in the US.
 

By 1915, city touring had marked significant shifts in the way Americans perceived, organized and moved around in urban environments. Urban tourism became a profitable industry in 1915 as the number of tour agencies, railroad passenger departments, guidebook publishers and travel writers grew at a fast pace. The expense of pleasure tours between 1850 and 1915 meant that only a minority of Americans could experience the luxury of tourism. Many Americans traveled to find work, but few found time for enjoyment of the urban environment. As transportation networks improved, the length of commuting decreased, and income rose. A growing number of Americans were able to afford short vacations by 1915. Still, mass tourism was not possible until after World War II. 

As American cities developed, new institutions to accommodate and care for the insane, disabled and criminal were constructed. The Hartford, Connecticut American School for the Deaf opened in 1817, Ossining, New York state prison (now known as Sing Sing) in 1825, the Connecticut State Penitentiary at Wethersfield in 1827, Mount Auburn Cemetery in 1831, the Perkins School for the Blind in 1832, and the Worcester State Hospital in 1833. These institutions attracted the curiosity of American and foreign visitors. The English writer and actress Fanny Kemble, an admirer of the American prison system, was also concerned that nature was being destroyed in favor of new developments. Guidebooks published in the 1830s, 40s and 50s described new prisons, asylums and institutions for the deaf and blind, and urged tourists to visit these sights.
 

Tourists spend more money in the United States than in any other country, but the United States attracts only the third-highest number of tourists, after France and Spain. The discrepancy may be explained by longer stays in the US.
 

In the United States, tourism is a large industry that serves millions of international and domestic tourists yearly. Foreigners visit the U.S. to see natural wonders, cities, historic landmarks, and entertainment venues. Americans seek similar attractions, as well as recreation and vacation areas. Tourism in the United States grew rapidly in the form of urban tourism during the late nineteenth and early twentieth centuries. By the 1850s, tourism in the United States was well established both as a cultural activity and as an industry. New York City, Los Angeles, Chicago, Boston, Philadelphia, Washington, D.C., and San Francisco, all major U.S. cities, have attracted numerous tourists since the 1890s. By 1915, city touring had marked significant shifts in the way Americans perceived, organized, and moved. During the early 20th century, many more people started to travel, partly because of the spread of the automobile. Similarly air travel revolutionized travel during 1945–1969, contributing greatly to tourism in the United States. Purchases of travel and tourism-related goods and services by international visitors traveling in the United States totaled $10.9 billion during February 2013. In the U.S., tourism is among the three largest employers in 29 states, employing 7.3 million in 2004, to take care of 1.19 billion trips tourists took in the U.S. in 2005.[citation needed] As of 2007, there are 2,462 registered National Historic Landmarks (NHL) recognized by the United States government. As of 2023, New York City is the most visited destination in the United States, followed by Miami, Los Angeles, Orlando, and San Francisco.
 

Tourism is the largest economic industry in the Maldives, as it plays an important role in earning foreign exchange revenues and employing 25,000 people in the tertiary sector of the country. The archipelago of the Maldives is the main source of attraction to many tourists visiting the island country. Entrepreneurs have been swiftly amassing assets connected to the tourism sector in the Maldives. Given that tourism is the primary economic driver in the Maldives, this trend is affording the substantial influence over the nation's economy.

The tourism industry is especially vulnerable to climate change: as one of the island nations expected to be most impacted by climate change, sea level rise and subsequent increased extreme weather, coastal flooding, and coral bleaching damage the natural attractions that bring many of the tourists to the country.
