The trend of adapting popular television dramas into film in Japan seems to be losing its charm, as the box office success of these movie adaptations is shrinking. This reflects a changing dynamic within the Japanese entertainment industry and audience preferences.

Japanese viewers are known for their loyalty towards popular TV series, often leading to successful movie spin-offs. However, this trend appears to be changing, with movie adaptations struggling to meet the same level of success. This shift could have significant implications for Japan's entertainment industry.

In the US or EU, TV series are often spun off into movies when they reach a certain level of popularity. The commercial success of these adaptations varies, however, typically they reflect the series' viewer ratings. There's also a trend towards creating spin-off series or sequels rather than full movies.
