percent stated that they use either depending on the situation. In another survey, over 90% of ethnic Koreans in Japan have a Japanese-sounding name in addition to a Korean one. Eighty percent stated that they used their Japanese names when in Japanese company, and 30.3% stated that they used their Japanese names "almost exclusively". Zainichi in the Japanese labor market Zainichi Koreans are said to mainly engage in pachinko parlors, restaurants/bars, and construction. Discrimination against Zainichi Koreans in hiring pushed them into so-called 3D (dirty, dangerous, and demeaning) industries. Annual sales of pachinko had been about 30 trillion yen since 1993, and Zainichi Koreans and Chongryon accounted for 90% of such sales. However, the pachinko industry is shrinking, because the Japanese government has imposed stricter regulations. The number of pachinko parlors decreased by 9.5% between 2012 and 2016, while the number of people playing pachinko dropped to less than 9.4 million. Some Zainichi Koreans have developed yakiniku restaurants. The honorary president of the All Japan "Yakiniku" Association is Tae Do Park (alias: Taido Arai). In the 1970s, newcomers started to enter the precious metal industry. Currently, 70% of precious metal products are made by certified Zainichi Koreans. Some Zainichi Koreans participate in organized crime, as do some people in other segments of the population. A former member of Sumiyoshi-kai estimates there are a few hundred Korean yakuza, and that some of them are bosses of branches. However, Korean gang members tend to go to China and Southeast Asia, as these countries are more lucrative for them than Japan. There has been improvement in the field of the working rights of Zainichi Koreans since the 1970s. For example, foreigners including Zainichi Koreans were not allowed to become lawyers in Japan, but Kim Kyung Deok became the first Zainichi Korean lawyer in 1979. As of 2018, there are more than 100 Zainichi Korean lawyers in Japan, and some of them have worked as a member of LAZAK (Lawyers Association of Zainichi Koreans). In popular culture The earliest Japanese films featuring Koreans in Japan often depicted Koreans as members of the peripheral society, rather than as main characters. It wasn't until after the Second World War that films visualized the struggles and oppression experienced by Zainichi Koreans, with films such as Three Resurrected Drunkards (1968) by Nagisa Ōshima, which addressed the bigotry and xenophobia experienced by Zainichi in Japan. The first film to
