"It is about what would happen if these warriors -- the toughest and best in Japan -- all of a sudden became common people and had to fight for their lives. Think 'Shogun' meets 'Squid Game,'" said Kaata Sakamoto, vice president of Japanese content at Netflix. In 2023, non-English-language titles accounted for 13% of Netflix's U.S. viewing hours, a threefold increase from 2015. This trend is particularly prominent in Korean-, Spanish- and Japanese-language productions. "Shogun," a drama created by FX under Walt Disney, stars Hiroyuki Sanada in the lead role. The series won 18 Emmy Awards in September, fueling renewed interest in Japanese period dramas. The success of "Shogun," with 70% of its dialogue in Japanese, highlights the impact of Netflix in offering subtitles for U.S. viewers. "American audiences are now used to subtitles because when we watch TV, movies and videos on our phones and tablets, we often keep the subtitles running to make it easier to follow even if there are noises around us," said Morgan Pitelka, a professor at the University of North Carolina.
