Java sparrows have been a popular cage bird in Asia for many centuries, first in China of the Ming Dynasty and then in Japan from the 17th century, often displayed in Japanese paintings and prints. Meiji-era writer Natsume Sasaki wrote an essay about his pet Java Sparrow. The United States was one of the most popular cage birds until the Java sparrow was banned in the late 1960s and early 1970s. California-based Asian countries, such as China, Taiwan and Japan, have no legal control over California because of the threat to agriculture.
In Asia, Java sparrows are often inherently raised by human breeders and owners, and they become very bitter and associated with humans. As such, they can usually be kept in a relatively small cage, but opt out for indoor practice without trying to escape. In captivity, a variety of colors including pi, java sparrow (Japan's Sakura bunch), including a white, silver / opal, von / isabel, pastel, cream and agate (which are rare in present-day European captive specimens) have been collected.
Java sparrow is considered by most countries as an agricultural pork in rice cultivation. Continued erosion of natural habitats, hunting in some areas and trapping of an animal in others have created very few numbers in the wild, and sightseeing in its natural range has become increasingly uncommon. Java Sparrow is assessed as a threat to the IUCN Red List (listed from weak in 2018) as a threat and is listed in Appendix II to the CITES. The breed has been subjected to grave threats by the illegal foreign pet business, according to Traffic.
