About this Program

This program is aimed for the expansion of implementation of renewable energy among commercial facilities by Tokyo Metropolitan Government actively, introducing renewable energy technologies which are at their initial phase of popularization and “visualizing” their capacity.

In 2020FY, solar panel pavement (paving solar panel to be installed on pavement surface) and vibration-powered generators (converts energy generated by vibration to electric power) were installed at Tokyo Big Sight to “visualize” their effect.

Two Models


Solar panel pavement


Solar panel pavement consists of layers of solar panels and glass light guide plates.
The surface is made of tempered glass with nonskid functionality and thus can be walked upon.
You can view the amount of electricity currently being generated by the solar panel pavement.


Vibration-powered generators

Power Generating Floor

This is a electrical power generation system using vibrational energy from pedestrians or vehicle movement.
The vibration-powered generator installed at Tokyo Big Sight illuminates LED lights when stepped on and it can also send information to LINE accounts.

Installation locations


These two models are being installed at the entrances of Tokyo Big Sight. Solar panel pavement has been installed in the outdoor entrance plaza. Two types of vibration-powered generator panels are installed in the indoor entrance hall.
