SAFECAST fundraiser in Tokyo, Nov. 4, 2014


Come spend an evening with SAFECAST!

As many who have been following Safecast know, our funding has come primarily from crowdfunding efforts like Kickstarter and GlobalGiving, and occasional grants from philanthropies such as the Knight Foundation. This is in addition, of course, to the many people who have contributed their invaluable time and knowledge. We have never done a fundraising event until now, but happily we were approached by a concerned local businessman who offered to try to set one up for us in Tokyo. We hope many of you can attend.

Date & Time: Tuesday, November 4th, 7:00pm
Location: Simmons & Simmons / TMI Associates conference rooms,
22nd floor, Roppongi Hills, 6-10-1 Roppongi, Minato-ku, Tokyo

Price: ¥5,000
Food/Drinks: Light food and refreshments will be served
RSVP/Questions: Please contact

With the generous support of Simmons & Simmons in association with TMI Associates,
100% of all ticket sales will go to SAFECAST .

Event Info:
The doors will open at 7:00pm to allow people to socialize and have something to eat. Starting at 7:30pm, SAFECAST co-founder Pieter Franken and his colleagues will provide a brief overview of SAFECAST’s success and results of collecting data on the nuclear radiation around Fukushima and all of Japan. This will include demonstrations of their interactive maps charting radiation data and their unique detector hardware. The overview will include SAFECAST’s current development of a new realtime sensor and information system being deployed around the Fukushima Daiichi nuclear power plant and others in Japan and around the world as an “early warning” system against future possible radiation releases. The event will also provide ample time for Q&A to cover radiation, food, health, and other issues of concern.


SAFECAST, a non-ideological, non-profit, volunteer-based organization created in the days immediately following the start of the Fukushima nuclear crisis in March, 2011, has become the most prominent and reliable independent source for radiation data in Japan and abroad. More than three years later concerns about radiation exposure from Fukushima continue, with low public confidence in government and industry statements that the nuclear fallout does not pose a significant risk to public health. The general public remains worried about the impact of long-term exposure, and lacking faith in government reassurances, has increasingly turned to alternative sources of information like SAFECAST.

In order to fill the acute information vacuum about the severity of the Fukushima fallout, SAFECAST has drawn on the expertise and experience of specialists worldwide, including co-founder Joi Ito (Director of the MIT Media Lab) and advisor Ray Ozzie (former CTO of Microsoft), to quickly field award-winning mobile detectors of its own design. These leverage open-source software and hardware and new-generation DIY tools such as laser cutters and custom PCB fabrication to dramatically accelerate development and deployment time. The group has simultaneously developed an information management system that allows GPS-tagged radiation data points to be uploaded into a central database and displayed on an interactive web-based and mobile maps.

Watch this short video summary of SAFECAST’s mission and principles by Adrian Storey:

The radiation data gathered by the growing group of SAFECAST volunteers in Japan and abroad currently exceeds 23 million data points, arguably the most extensive public data set of its kind. It was soon hailed as a technically competent, credible, and objective source of radiation information for Japan by experts on both sides of the nuclear power debate.

SAFECAST’s unique open-source hardware and software and crowdsourced maps and radiation data have all been developed by volunteers and are freely available without restriction for download and use.
