The impact of the Great East Japan Earthquake on the Japanese financial systemIntroductionJapan is located in an area where several Tectonic plates meet. Earthquakes frequently strike the Japanese archipelago - minor tremors occur almost daily, while serious disasters - are rare, but they have nevertheless had serious consequences in terms of direct and indirect impact on the economy, and therefore on the financial system. Earthquakes are usually associated with damage and loss, and Japan is no exception. However, Japan remains the world's third largest economy measured by gross domestic product (Ro, 2013). The most disastrous earthquakes in Japanese history over the past 100 years occurred in 1923, 1995 and 2011 - the Great Kanto, Kobe and the Great East Japan Earthquake (GEJE) , respectively. According to the findings of Peter G. Zhang, the Great Kanto Earthquake destroyed most of western Tokyo, leading to an increase in the inflation level of 15%, resulting from a severe shortage of goods in addition to huge government spending (Zhang, 1995). ). After the Kobe earthquake, the Japanese economy fell into a long decline, except for the short period when reconstruction spending temporarily boosted the economy (Hayashi, 2012). The Great East Japan Earthquake that struck the country about 3 years ago was the most powerful earthquake ever recorded in Japan. Although the post-disaster reconstruction phase cannot be considered complete, the response to the earthquake is already the subject of much debate. The physical damage in the areas affected by the earthquake was enormous, but despite this, Japan's financial system, which is a critical infrastructure that supports people's lives and economic activity, continues steadily...... mid paper ......datastream database. The extracted GDP data consists of quarterly entries collected from 2006, quarter I, until 2013, quarter III. Daily Nikkei 225 values ​​are extracted from January 2, 2006 to January 1, 2014. Nikkei 225 industrial indices, calculated on a daily basis, are also exported from Datastream. The indices are calculated using the same method as the main Nikkei 225 index, so no further adjustments are necessary. Since the index is weighted by price rather than value, the authors use the relative change in prices rather than the absolute change due to the difference in size of each industry. To compare the relative impact on industries, the following formula is used: P1P1=(Pt1-Pt0)/Pt1) The acquired data will be organized with MS Excel and STATA statistical software will be used for regression analysis.
