NHK Archives

In 2013, NHK changed its broadcasting system from tapes to file servers. The NHK Archives now receive a direct feed that enables us to save every program. Producers enjoy hugely increased convenience. They can use their own computers to search our database, watch reference videos, and order clips. They get the footage they need in an average of just seven hours.

Videotapes deteriorate over time. The NHK Archives restore discolored or damaged footage so it can be broadcast again and preserved for posterity. We first remove dust and other particles. Then we copy the content into digital file. We have to retouch every scratch and splice. On average, we need to do 60 hours of work to restore a 30-minute program. NHK airs restored content in a range of programs.

Restoration

NHK's past programs convey messages that remain relevant today, so the NHK Archives have a production unit that creates shows using archived content. Interviews with famous people who are no longer alive offer insight into unique philosophies and paths to success. And content from popular programs such as “NHK Special” documentaries sheds light on tumultuous chapters in Japan's modern history.

An Open Program Library

Every NHK facility throughout Japan contains an Open Program Library-a public space where people can watch past NHK programs free of charge. Viewers can choose from a diverse range of programs dating back to the earliest days of television. Highlights include dramas, year-end song festivals, documentaries, and travel shows. The library at the NHK Archives in Kawaguchi is the largest. Visitors can watch over 10,000 programs on 70 terminals.
