Abstract	In many companies of the province of Tohoku (North-East Japan), stock prices were declining just after the East-Japan earthquake. However, on the other hand, some companies' stock prices rose in Tohoku. We have analyzed the reasons using text mining technologies on web data. In our studies, a combination of a stock price analysis and the text mining of the company can weave unexpected facts like a word associative game. First we surveyed stock prices of all listed companies that were headquartered in the damaged three prefectures in Tohoku. Then, we found the remarkable growth of YAMAYA which was an alcohol wholesaler and retailer company. The headquarters are located in Sendai-city, the capital and biggest city of Miyagi prefecture. On the other hand, we found YAMAZAWA's growth which was the same kind of an alcohol retailer company as YAMAYA. Although stock prices of almost all super markets in Tohoku intensely grew just after the disaster, the growth of YAMAYA and YAMAZAWA was distinguished. Therefore we conducted text mining to seek the reason of the company's stock price increase. As a result, we thought the alcohol consumption in Sendai-city caused the rapid stock price rises. In addition, from the comparison, we found that the recovery of YAMAZAWA's was quicker than that of YAMAYA's. We think that the reason for the YAMAYA's delay is that the earthquake damage in Sendai-city was larger than that in Yamagata. YAMAWA is headquartered in Sendai-city and YAMAZAWA is headquartered in Yamagata prefecture. The difference about locations would make the delay in the stock price recoveries. From the analysis, we inferred that an increase of alcohol consumption was one of the triggers for the economic reconstruction in Sendai-city. The paper discusses the economic reconstruction processes through increases of stock prices in the Tohoku province.
