These photos kindly sent to us of manholes in the Osaka area show not only a fascination with Japanese manholes but also the area they occupy and how they blend into the sidewalk and surrounding streetscape.
You can view the originals and more manholes here.
Indeed, Japanese manholes are soon to go hi-tech, three Japanese companies - Bitcom, KDDI and Pasco are working together on a project to equip manhole covers in Japan with RFID (Radio Frequency Identification) tags to monitor the status of underground gas and sewage utility pipes in the event of a disaster such as an earthquake, the so-called “Intelligent Manhole System”.
In China, the authorities will begin tagging up to 1,000 manholes in Beijing, as reportedly around 24,000 manholes in China disappear each year to be sold off as scrap.
