Kaoru Kubo welcomes thousands of travellers to Japan every day. A former announcer for public broadcaster NHK Kubo has, for 23 years, been the voice of the Airport Limousine buses that ferry passengers to and from Narita Airport. Her announcements are said in both Japanese and English, and her no-nonsense delivery has a cult following. It's also a quick introduction to Japanese etiquette. Once she's told you not to, you won't even think about chatting on your mobile phone. (With thanks to Airport Limousine).
