Before the pilot made a hard landing. The jet then veered off the runway before coming to a stop. More than 20 passengers were injured. Officials with japans transport safety board released their analysis of data from the flight recorder. They say the aircraft started to lose too much altitude after the pilot switched from automatic to manual control. They say that happened one minute before the accident, and they say the pilot then tried to lift the planes nose about two seconds before touching down by applying full engine thrust, but the investigators say the engines did not produce enough power and the aircraft failed to climb. They also say the possibility of turbulence being behind the altitude drop is low. U. S.

Ramin mellegard joins us from the tokyo stock exchange. What are you seeing so far . The april u. S. Retail sales were weaker than expected and that pushed the dollar a little bit lower and putting doubt in investors minds as to the timing of the Federal Reserve when it may want to raise rates. But lets have a look how that is affecting the nikkei and the topix here and both indexes in the negative. The nikkei rose to twoweek highs on wednesday. And nissan didnt disappoint. As a weaker yen provided a boost to its bottom line. The car maker reported a net profit of 3. 8 billion in the fiscal year through march. Record sales in the u. S. Of course helped.

Ramin mellegard from the tokyo stock exchange. Well hear from him in a few hours time. Its time for view from the top, where Business Leaders explain how they stay ahead of the competition. Today we hear from elon musk, the pioneering ceo of u. S. Electric carmaker tesla motors. Musk has turned his attention to other ventures, including commercial space exploration. These days, hes been busy promoting batteries Strong Enough to power your home. Musk also wants to make his mark in japan. Nhk worlds rosa sabrino has this report. Reporter the innovative tech entrepreneur recently surprised the world with a bold announcement, he announced tesla will manufacturer rechargeable batteries that can supply Household Energy needs. We have to come up with the solution. Thats the missing piece. As thats the thing thats needed to have a proper transition to a Sustainable Energy world. Reporter demand for home batteries is rising around the world, for use as an emergency backup power source and to store surplus electricity generated by solar power systems. Musk says teslas new products are very different from existing batteries in the Energy Market which are typically expensive and bulky, and it will help with the worlds transition to Sustainable Energy. The way i see the longterm future of the world is, like, we have to say, okay, everything has to be renewable and sustainable. So, in order to achieve a Sustainable Energy future, in order to have a good future, essentially, we have to have sustainable power generation, which i think is primarily solar, but combined with also wind and geothermal and hydro. And then youve got to combine that with battery packs. Youve got to be able to store the energy you produce during the day so that you can use it at night. And then you combine that with electric transportation, and now you have a fully sustainable future. Reporter teslas battery is unlike anything thats ever been produced. Previous efforts by rival companies have been boxy and sit on the floor. Teslas battery, however, is designed to be mounted on the wall. Previously if you look at home battery packs, they are big and heavy and they are on the ground and you need a whole room, special room for them and they tend to be usually lead acid, and then they sort of smell bad and they look bad. And so, thats why people dont and they were expensive. Thats why people dont want them. Reporter one of the most notable features is the price. A model with the capacity of 10 kilowatt hours will sell for 3,500. Thats much cheaper than comparable batteries produced by japanese firms. Tesla executives are now planning to build a huge battery factory in the u. S. State of nevada. They hope to cut costs by expanding production, and they aim to begin selling their batteries in japan soon. Tens of gigawatt hours of demand, i suspect, maybe hundreds of gigawatt hours of demand, just in japan alone. Were going to offer our product, if its the right product, people will buy it. And then probably others will if ours is successful, others will copy it, and then they will get closer to our product, but thats fine. Im just saying, like, the future in order for us to have a good future, we have to have, in my view, solar power, plus batteries, plus electric cars, and then its good times. Reporter musk changed the way people thought about electric cars, and he slashed the cost involved in launching a rocket. Now he appears to be on the verge of transforming the market for rechargeable batteries. Rosa sobrino, nhk world, los angeles. More for you in business next hour. Ill leave you with a check on markets. An International Defense and security exhibition has opened in japan. Its the first time for the country to host this county of event. Japan has long banned the export of arms. Nhk worlds takefumi terui reports. Reporter more than 120 countries around the world are participating in the gathering in yokohama near tokyo. These include japan companies. The event opened on wednesday. They are displaying maritime technologies and defense equipment. The nation banned arms exports starting in the 1970s. Prime minister shinzo abe changed that principle last year. Japanese companies now can export defense equipment under strict restrictions. At the Opening Ceremony on wednesday, the head of japans maritime selfdefense force noted the change. Now the transfer of defense equipment and technology for maintaining National Peace and safety is permitted. I think japan will make both personal and material contribution toward capacity building. Reporter japanese manufacturers see the exhibition as a key opportunity to reach out to foreign markets. 12 companies are jointly displaying their products. These include Maritime Communications systems and replicas of vessels. Translator we plan to expand our market share with products that can contribute to the peace and security of society. We feel many people are interested in these items. Reporter International Visitors are eager to use the event to form Collaborative Networks with japanese companies. We are interested in what the Japanese Defense industry has to offer. Reporter the organizer emphasizes its importance. People dont know quite to expect from japan. So this is the first time people have been able to talk openly about what their offerings are. And i think its an ongoing process. It wont happen just in these three days. This will be something that is revisited in years to come. Reporter the fair will continue until friday. The organizer expects thousands to attend. Takafumi terui, nhk world, toke hama. The japanese government is stepping up efforts to get more of the countrys modern industrial sites on the unesco World Heritage list. Its sending staff around the world to drum up support. The International Council on monuments and sites recommended earlier this month that 23 sites around japan be given world Cultural Heritage status. The facilities are located in eight prefectures. They date back to japans Industrial Revolution in the late 19th and early 20th centuries. The World Heritage committee will screen the recommendations for a formal decision at a meeting in germany in july, but one of the 21 member nations of the committee opposes listing the facilities. South korean members say they include sites where many koreans were forced to work. Senior japanese government officials are being sent to other member nations to seek support for the unesco listing. Theyre set to hold talks with their south Korean Counterparts on may 22nd. They want to explain that the sites have historic value as artifacts from the meiji revolution. Many public facilities went up with japans revival in the 1950s, 60s and 70s. They now are liabilities. Communities are finding they cost too much to keep up and too much to tear down. Nhk worlds Yasuhiro Kobayashi explains. Reporter a workplace that used to be the center of activity in the section of saitama, a city next to tokyo. Soon, nothing will be left of it. The building became decrepit and could not easily be converted to another use. So the city decided to tear it down. This office is one of about 1,700 public facilities in saitama. The older ones are especially expensive to maintain and the city is not planning to build any new ones in the near future. Translator more than half of the buildings are at least 30 years old. No matter what we do with them, we need to reduce the overall number of public facilities. Reporter nationwide, a Government Survey shows more than 12,000 public facilities targeted for demolition. Most are Public Housing and schools. Tearing them down will cost nearly 3. 5 billion. The National Government allows communities to issue Municipal Bonds to pay for the work. In that way, they can raise 75 of the money from financial institutions. Some local governments, though, are hesitant to use bonds. Reparations are shrinking. The city of ritto is one such place. It already has cut back administrative services. It decreased the subsidy for buses and stopped providing lunches for junior high students. Even so, the cost of dismantling public facilities far exceeds the savings from those budget reductions. It will have to pay about 590,000 to tear down a community center. Another building, a welfare center, has already been closed for six years. Getting rid of it will cost another 420,000. City officials worry that paying for the work with bonds will cause even worse financial problems down the line. Translator we would like to dismantle the structures as soon as possible. However, under the current conditions, we cannot formulate a plan. Reporter some other local governments are trying a different approach, increasing usage fees to pay for maintenance. The city of ichikawa in chiba prefecture has tripled the charges in some cases for access to community and sports centers. It expects a population decline to cause a shortfall in tax revenue. So, it wants to establish another income stream for the facilities. One economist suggests that local governments look at the big picture. Translator municipalities should find ways to generate income, even if only by a little. For example, by working with private organizations. A variety of things should be on the table. Overall plans should include both the dismantling of buildings and preservation. Reporter depopulation is no longer just a possibility. For many communities, it is a near certainty. Somehow, they will have to come to terms financially with a new normal. Yasuhiro kobayashi, nhk world. Lets get a check on the weather. Many people in tokyo are enjoying a warm and sunny morning. Mai shoji joins us with more in world weather. Yes, i really like this weather, too. Its not too hot during the night hours, so, we actually get a good sleep, too, but its going to get, again the mercurys setting up to the 30s again today. So, this consecutive heat could lead to some heat stroke, so we should watch out for that. We have some images coming up from yesterday, what people were dealing with. Tokyo and many parts of japan are getting ready for another round of warm temperatures today with the mercury expected to climb in the 30s for the second day in a row.
