One of the latest Japanese developments in transport industry is an ecological taxi (based on some previous - well tested models). Its main advantage - no polution, the main drawback - needs two drivers. Some bus models based on the same concept are currently under development.
Ecology has also strong influence on fashion - as an example some new raincoat designs.
