Japan's carmakers developing rare-earth recycling technology
The project has taken on a new urgency since China announced in April it will restrict exports of rare earths.
The process involves melting the motor in an electric furnace with other chemicals to separate off the rare earths. The metals are essential to manufacturing EVs.
Nissan Motor Senior Engineer Ogawa Kazuhiro says the technical challenge is to increase the amount of rare earths they can recycle from the magnets.
"We hope to have the system in practical use for when more scrapped electric motors are available," he said. "That is expected to be around 2030."
Toyota Motor is also testing a technology to recycle rare earths from hybrid car motors.

Japan to accelerate development of logistics network in Africa
Prime Minister Shigeru Ishiba will unveil Japan's plan to accelerate the development of the Nacala Corridor, a logistics network in Africa, at the upcoming ninth edition of the Tokyo International Conference on African Development (TICAD), informed sources said. The planned corridor, which will link the inland African country of Zambia and a port in Mozambique in the southeastern part of the continent via Malawi, is aimed at enhancing supply chains for mineral resources. Zambia is a mineral-rich country, and minerals such as copper and cobalt produced there are mainly exported through ports in Angola, western Africa. Using Nacala port in Mozambique, however, is more convenient for exports to Japan. The Japanese government has been developing the Nacala Corridor since 2012. At the three-day event starting Wednesday in Yokohama, Ishiba, who will chair the conference, will pledge Tokyo's support for the three countries hosting the Nacala Corridor by utilizing investment and loan programs of private firms and international organizations, as well as the government's official development assistance program. Specifically, Japan will support the development of water facilities and highways in order to promote industrial growth and increase the value of the areas. Japan is slated to launch a new initiative to strengthen economic ties with India, the Middle East and Africa. The government will support Japanese companies' advances into these regions by helping expand trade and investment through the new economic initiative and the Nacala Corridor. By leveraging the Nacala Corridor, Japan aims to increase its competitiveness with China, which is trying to increase its presence in Africa by providing countries in the continent with subsidies. Establishing solid supply chains for critical minerals is "directly associated with Japan's economic security," a Japanese government official said. "The development of the Nacala Corridor will contribute to the development of Africa and also benefit Japan." U.N. Secretary-General Antonio Guterres is slated to visit Japan in order to attend the conference, where he will underscore TICAD's importance and the potential growth of Africa, a spokesperson said Friday. After attending the conference, Guterres is slated to visit the Osaka Expo.

Smoke disrupts Tokaido Shinkansen services in central Japan
A Japanese railway company says bullet train services on the Tokaido Line on Friday night were temporarily suspended. Central Japan Railway Company and police say that after leaving Shin-Osaka station, conductors on the Kodama No. 764 bound for Shizuoka smelled something burning shortly after 10 p.m. At Gifuhashima station, crewmembers say they discovered white smoke coming from beneath the No. 9 car and reported it to the local fire department. Fire fighters then identified a fire underneath the car, which took about two hours to put out. The estimated 250 passengers were safely disembarked and operations of the Kodama train were suspended. The passengers later boarded a Nozomi shinkansen. The incident caused delays of up to 52 minutes in shinkansen operations, affecting about 3,800 passengers. JR Central is examining the car to determine what caused the blaze. The company says Tokaido Shinkansen services had resumed normal operations on Saturday.

Taiwan foreign minister's visit puts damper on Japan-China relations
Taiwanese Foreign Minister Lin Chia-Lung's latest trip to Japan has put a damper on Sino-Japanese ties, with Beijing canceling at the last minute a bilateral meeting of agriculture ministers. Chief Cabinet Secretary Yoshimasa Hayashi avoided going into detail during a news conference Friday, stating only: "We understand that (the ministerial meeting) was not held due to scheduling conflicts of both sides." Chinese agriculture minister Han Jun was set to visit Japan to hold a meeting with his Japanese counterpart, Shinjiro Koizumi, on Tuesday, after a trilateral agriculture ministers' meeting involving the two nations plus South Korea held in Incheon near South Korea's capital, Seoul, on Monday. Many within the Japanese government consider Lin's Japan visit in late July to be the reason for the cancellation. The Taiwanese side has said that the foreign chief had made a personal visit to Japan. During the trip, however, he held talks with Keiji Furuya of Japan's ruling Liberal Democratic Party, who heads a suprapartisan group of Japanese lawmakers aiming for stronger Tokyo-Taipei relations, and other Japanese officials. In light of heightened tensions between China and the United States, Beijing has been pushing for improved ties with Japan. In autumn last year, China resumed its visa exemption for short-term stays by Japanese nationals. It announced in June this year the restart of imports of Japanese fishery products. The Chinese government has been especially sensitive about the Japanese government's historical perceptions and Taiwan issues due to it marking the 80th anniversary this year of its victory in the past war against Japan. A senior official at the Japanese Foreign Ministry said, "China had to take a strong response based on moves by Taiwan." Lin's trip may also impact Japan-China high-level talks expected to be held on the sidelines of a series of summits related to the Association of Southeast Asian Nations in Malaysia in October.
