Been meaning to get round to it for a long time but will try to review all the equipment that we use for TV production.
Narration (known as "Afureco" in Japanese which is short for "After Recording") for Culture Japan Season 2 is done in my office. For the pilot episode of Culture Japan Season 0, we used a studio in Roppongi who charged us 200000 yen for using their facilities - and for only a few hours!
My production budget would run out pretty quick if we carried on like that so decided to do it myself.
