Working for Recovery from Great East Japan Earthquake – Yahoo! JAPAN’s Initiatives Seen from Data

After the Great East Japan Earthquake in 2011, Yahoo! JAPAN has undertaken various initiatives, including emergency relief assistance and reconstruction support activities.
This page looks back on some of our efforts made to date with data, including the amount of money and number of people involved in supporting the Tohoku region.
In July 2012, Yahoo! JAPAN opened Yahoo! JAPAN Ishinomaki Recovery Base (currently Yahoo! JAPAN Ishinomaki Base), as a hub for its disaster recovery business. Three or more employees have been stationed to engage in disaster recovery in the Tohoku region.

The figures included in this page are based on the data analyzed and provided by K-three Inc. ©2021 K-three Inc.

People and organizations associated with Yahoo! JAPAN Ishinomaki projects

Yahoo! JAPAN Ishinomaki Base has established relationships with 8 local companies and NPOs, 1 governmental organization, 2 media companies, and 1 local university in Ishinomaki City. Outside of Ishinomaki, Yahoo! JAPAN Ishinomaki Base has established relationships with four local companies and NPOs, four local governments, and two media companies in the Tohoku region. In addition, there are 14 companies outside of the Tohoku region that have collaborated with Yahoo and 7 companies that have provided individual support. We conducted a survey to determine the percentage of businesses that have been developed/maintained due to Yahoo! JAPAN's presence in Ishinomaki City and those outside of Ishinomaki City in Tohoku. The results were 73% for those in Ishinomaki City and 69% for those outside of Ishinomaki City. We also took a questionnaire on the percentage of respondents who have used services, etc. related to earthquake recovery support, and the results were 77% for Ishinomaki officials and 56% for Tohoku officials outside Ishinomaki City.

Voices of people in and outside Ishinomaki City

Thanks to Yahoo! JAPAN and members who stood by Ishinomaki City, we were able to make our wish come true and were able to deliver “Made in Ishinomaki” products to a lot of people.

As we are passing a milestone, I would like to express my sincere thanks to the people involved in Yahoo! JAPAN Ishinomaki projects. It was very encouraging for us living in the area and across Japan to see that a big company like Yahoo! JAPAN set up a base for recovery in the devastated Ishinomaki, ahead of everyone else and launched a variety of projects. Your work has opened up the potential of the local areas.

Working with Yahoo! JAPAN has brought me a number of things: ideas never thought of in the conventional fishery, visions for the future, and change of awareness. Yahoo! JAPAN has triggered transformation in Ishinomaki.

The very fact that many actions were taken at the time of catastrophe encouraged many people and created a huge impact on society that cannot be measured by numbers.

Voices of employees

I was a student living in Tohoku and was just in the middle of a recruitment seminar held by Yahoo! JAPAN in Roppongi, Tokyo when the earthquake struck. I saw the company take swift actions to support reconstruction ahead of other Internet service companies, and as I was luckily offered the job, I decided to join the company.
I am proud to be part of the company that has continually supported the reconstruction since then.

Using my personal time, I helped an antenna shop for Ishinomaki as a volunteer for nine years. The fact that the company I work with is responsibly engaged in reconstruction projects had positive effects on my off-the-job activities, motivating me and sometimes leading to actual deals.
