Ikiya lives in Fukushima, Japan and has been actively mapping on OpenStreetMap since 2008. In 2011, a massive earthquake and tsunami caused major damage to the Fukushima area, including a nuclear accident. Ikiya documented the changes to the area by mapping radiation levels and the coastline before and after the disaster. Though recovery continues, normal life has mostly returned to Fukushima. Ikiya enjoys participating in the local OSM community through mapping parties and educational events.

A survey by GSI(Geospatial Information Authority of Japan)
has revealed that land in the Tohoku region moved
to the south-east in the earthquake.
Ishinomaki City in Miyagi Prefecture moved up to
5.3meters.
The earth's crust had
moved.

12. After the disaster
Japan had a lot of support from around the world.
Thank you very much
for all your kind support.

much of the debris out to sea.

I mapped the radiation levels in Fukushima.

21. I recorded 2,400 km,
7,000 waypoints.

4 years has passed since the disaster.

23. Fukushima 2015
The people living in Fukushima
have mostly settled down to a normal life again.
But, nearly 120,000 people who were evacuated

Aizu-Wakamatsu City Fukushima, Japan

35. December 2014, Aizu-Wakamatsu City Crisis Management Division made
"Home Disaster-Prevention Chart" and "Hazard Map".(Fukushima,Japan)

36. The base map of these maps has used road and building data of OpenStreetMap,
and is made up in the form of overlapping the disaster information
that is provided by the National and Fukushima Prefecture.

37. These Paper Maps were enclosed in News of Municipal Government
and distributed to all households of Aizu-Wakamatsu City. (50,000 copies!)
