Japanese drama (テレビドラマ terebi dorama?, television drama), also called dorama (ドラマ?), are television programs that are a staple of Japanese television and are broadcast daily. All major TV networks in Japan produce a variety of drama series including romance, comedy, detective stories, horror, and many others. For special occasions, there may also be a one- or two-episode drama with a specific theme, such as one produced in 2015 for the 70-year anniversary of the end of World War II.
Japan drama series are broadcast in three-month seasons, with new ones airing each season. The majority of dramas are aired weekdays in the evenings around 9:00 p.m., 10:00 p.m., or even 11:00 p.m. Dramas shown in the morning or afternoon are generally broadcast daily, and episodes of the same drama can be aired every day for several months, such as NHK's asadora, or morning dramas. The evening dramas air weekly and are usually nine to twelve episodes long, though sometimes there will be an epilogue special made after the final episode if the show has been a huge success.
