Bicycle couriers, with their racing tadpole heads, dragonfly sunglasses, antennae and array of weirdly labelled backpacks, don't stand out much in Tokyo.
For one thing, they need to dress a bit more outrageously if they want to be seen in a city that brooks no rival for bizarro-style.
Arrayed against a mohawked punk carrying a mobile phone in the shape of a penguin, or a bright-orange tanned, grey-haired teenage girl in Hawaiian beach gear on 25cm clogs, your average bike courier is a little too straight.
There aren't many courier services, but that is changing rapidly. Tokyo, with its flat streets, crowded roads and expensive transport, is perfect for them.
Now, a romantic comedy-come-action movie, Messengers, starring a Japanese rock star and the hottest actress in the country, has opened. Several television specials have been scheduled. While Japan's best established service, T-Serv, has been around for 10 years, for most city dwellers couriers are a new, fun and attractively non-conformist tribe.
Unlike in Australia, where courier backlash has well and truly set in, people in Tokyo still look on in quiet admiration as a manic courier hurtles down the wrong side of the road before swinging onto the footpath, scattering a few pedestrians and screeching to a halt in the glistening foyer of some imposingly modern office building.
The Yomiuri Shimbun described bike courier as "one of the coolest professions in the nation" in a profile on Koichi Idei, a 20-year-old college student, describing him as a "big man on campus, besieged with requests for interviews about cycling and his courier business".
T-Serve, the model for Messengers, has increased its riders from two to 80. Other, similar services are springing up in the capital.
Motorcycle couriers are well established in Japan but T-Serv undercuts them on price about ´2,350 per trip compared with ´2,850 while regularly being quicker, particularly on bad traffic days.
Says T-Serv founder Takayuki Ikeya: "The beautiful thing about a bicycle is that it can move freely you can cut through parks, ride along sidewalks, go the wrong way down a one-way street and use crossings as well as roads."
