Princess Mako will get engaged to her former classmate Kei Komuro, who is a law firm worker and graduate student from Tokyo’s Hitotsubashi University. Japan’s Princess Mako, granddaughter of Emperor Akihito and the elder daughter of Prince Akishino and Princess Kiko, is expected to get engaged to a former classmate, Kei Komuro, 25, who is a law firm worker and graduate student and once starred in a tourism campaign as "Prince of the Sea,” reports said Tuesday. The pair will get married sometime next year, the Imperial Household Agency confirmed the news to Japan's national broadcaster NHK, Tuesday. The engagement will be the first among the four grandchildren of the emperor and Empress Michiko. Both Mako and Komuro studied at Tokyo’s Hitotsubashi University. Komuro has been a resident of Kohoku Ward in Yokohama, near Tokyo. According to an agency source, Princess Mako first met Komuro about five years ago through a friend at International Christian University that they both went to. Mako later accepted the marriage proposal from Komuro. The source also told Japan Times that Prince Akishino and his wife Princess Kiko have given their blessings to the couple in acceptance.

She has a major in arts and cultural property studies from the university. She also studied at the University of Edinburgh in Britain as an exchange student for nine months. After completing her graduation, she went on to study at the University of Leicester in Britain, where she completed her master's degree in art museum and gallery studies in January 2016. Currently she is studying in a doctoral program at ICU and also is an affiliate researcher at the University Museum of the University of Tokyo. She also performs some official duties by attending ceremonies and serving as honorary president of some events like the Tokyo International Book Fair. Mako’s husband-to-be did not answer any questions regarding the engagement and told reporters: "I would like to talk about it when the time comes." Read: Japan-Russia War?

Once Mako gets married she will no longer be a princess but a commoner. “I personally think a female imperial member should be allowed (to remain in the family),” said Meiko Hirayama, a 44-year-old employee at an accounting firm told CNN. “I guess the male line of succession would be kept through the crown prince and his brother, but I think there should be no problem that there could be a female emperor someday,” Hirayama added. However, another man named Katsuiji Tsunoda of Japanese nationality said he would like the heir to the throne to be male. “It's a tradition that has continued for over a thousand years. If we go with the global trend, anyone could be the emperor,” he told CNN. “We must respect tradition.” The news of Mako’s marriage came at a time when Prime Minister Shinzo Abe's government has been preparing a bill for submission to the current Diet session in order to enable the 83-year-old emperor Akihito to transfer his thrown to Crown Prince Naruhito. If that happens then this will be Japan’s first abdication in around 200 years.

Retirement is a major life-course transition that is closely related to changes in health. This study examined the dynamic impact of retirement on health and health behaviors, distinguishing an immediate change in the level of health at retirement and a change in the rate of change after retirement. We used panel data from 9283 individuals (4441 men and 4842 women) who had retired during a nationwide ten-year panel survey in Japan conducted in 2005–2014. We focused on three health behaviors (current smoking, heavy alcohol drinking, and leisure-time physical activity) and two health indicators (self-rated health and psychological distress). We estimated regression models that controlled for both time-invariant individual attributes and the endogeneity of retirement, using panel data collected during the five years before and after retirement. Results generally confirmed that the transition was accompanied by favorable changes in health and health behaviors with some gender differences. Among men, retirement immediately promoted leisure-time physical activity and reduced poor self-rated health and psychological distress. Retirement also accelerated smoking cessation and leisure-time physical activity and decelerated reporting poor health. Among women, retirement immediately promoted leisure-time physical activity and reduced psychological distress, while it did not affect the rate of change in any health variable after retirement. The current study underscores the need for more in-depth knowledge of the dynamic impact of retirement on health. This will assist in developing policy measures to help the middle-aged population make healthy transitions from work to retirement. © 2017 Elsevier Inc.

The portfolio optimization problem in which the variances of the return rates of assets are not identical is analyzed in this paper using the methodology of statistical mechanical informatics, specifically, replica analysis. We defined two characteristic quantities of an optimal portfolio, namely, minimal investment risk and investment concentration, in order to solve the portfolio optimization problem and analytically determined their asymptotical behaviors using replica analysis. Numerical experiments were also performed, and a comparison between the results of our simulation and those obtained via replica analysis validated our proposed method. © 2016 American Physical Society.

The estimate raises the decommissioning part of the total costs to 8 trillion yen ($70 billion) from the current 2 trillion ($17.5 billion) because of surging labor and construction expenses. Panel officials said the numbers could still grow as experts learn more about the damage to the plant's reactors and determine fuel removal methods. Costs for compensation, decontamination of the area and waste storage have also grown significantly. The plant suffered multiple meltdowns following a massive March 2011 earthquake and tsunami. Officials say its decommissioning will take several decades. Rising cost estimates mean an increased burden on consumers. Kunio Ito, a Hitotsubashi University professor of commerce who heads the panel, said it is inevitable that the plant operator, Tokyo Electric Power Co., or TEPCO, will pass on to customers part of the costs. He said the cost estimate for decommissioning is sketchy, but is needed to show the public how much the national project will roughly cost. The estimated increase of 6 trillion yen ($53 billion) is modeled after the example of the Three Mile Island nuclear plant cleanup in Pennsylvania following its 1979 partial meltdown. The TMI cleanup took five years and nearly $1 billon to remove 136 tons of melted fuel from one reactor. The Fukushima plant has twice as much melted fuel in each of three damaged reactors, meaning six times as much melted fuel must to be removed, the government-funded decommissioning and compensation organization said. It came up with the figure of $53 billion by factoring in the more extensive development of robotics and other equipment needed at Fukushima. The estimate does not include the cost of final waste management. The panel has been discussing ways to keep TEPCO alive so it can cover the cost that it is responsible for. TEPCO has already received a government bailout, and the panel urged Fukushima cleanup-related operations to effectively stay under state control until the next review in 2019. The 10-member panel commissioned by the Trade and Industry Ministry plans to urge TEPCO to conduct a drastic restructuring and reforms, possibly with a new business alliance with companies in and outside Japan, to stay afloat. The panel will submit its recommendations in a final report to Trade and Industry Minister Hiroshige Seko later this month. "This is a chance for innovation and cost-cutting to push forward Fukushima's reconstruction," Seko told reporters. "We expect TEPCO to fulfill its responsibility." TEPCO President Naomi Hirose, who was summoned to parliament Friday, pledged to live up to expectations. Explore further: TEPCO's Fukushima compensation cost to reach over $57 bn

The purpose of this study was to investigate gender differences in the associations of life satisfaction with family and social relations among the Japanese elderly. Ordered logit models were estimated to explain life satisfaction with a rich set of explanatory variables, using micro data of 3,277 elderly Japanese adults (1,679 men and 1,598 women) collected from the first-wave sample from the Japanese Study of Aging and Retirement (JSTAR). This study found that men are less satisfied with life when living without their spouse; women are less satisfied with life when they live and/or have close relations with their parents-in-law; coresidence with an unmarried son is negatively associated with life satisfaction for both men and women; and, a larger number of friends and social activities enhance life satisfaction for women but not for men. Men are more sensitive than women to overall family relations, while the relative importance of social relations is higher for women. These results confirmed gender differences in the associations of life satisfaction with family and social relations in Japan-a nation characterized by a gender-asymmetric society and multi-generational family settings. © 2012 Springer Science+Business Media, LLC.

Using industry- and micro-level data, this paper examines why Japan's productivity growth has been slow for such a long time and how it can be accelerated in the future. Japan's capital-gross domestic product ratio continued to increase after 1991, and this increase in the capital-gross domestic product ratio must have contributed to the decline in the rate of return on capital in Japan by decreasing the marginal productivity of capital. On the other hand, Japan's accumulation of information and communication technology capital and intangible investment was very slow. Compared with large firms, which enjoyed an acceleration in the total factor productivity growth in recent years, Japanese small- and medium-sized enterprises were left behind in information and communication technology capital and intangible investment, and their productivity growth has been very low. Furthermore, as large firms expanded their supply chains globally and relocated their factories abroad, research and development spillovers from large firms to small- and medium-sized enterprises seem to have declined. © 2013 Japan Center for Economic Research.

It is widely known that the mental health of middle-aged adults is closely associated with involvement in family caregiving, as well as socioeconomic and sociodemographic factors. However, most studies focusing on mental health in adulthood have not fully controlled for time-invariant factors. Moreover, the relative importance of factors associated with mental health has remained largely understudied. In the current study, we employed fixed-effects regression models to examine the manner in which middle-aged adults' mental health is associated with involvement in family caregiving and socioeconomic and sociodemographic factors, after controlling for time-invariant factors. Using data from a population-based, six-year panel survey in Japan, we focused on the evolution of the Kessler 6 (K6) scores (range: 0-24) for 26,522 individuals (12,646 men and 13,876 women) aged 50-59 years in 2005 over the subsequent five years. We found that men and women experienced 0.54 (95% CI 0.44-0.64) and 0.57 (95% CI 0.49-0.66) unit increases in their K6 scores, respectively, when they became involved in care provision for any family member. This magnitude of distress exceeded that associated with any socioeconomic or sociodemographic factor examined in this study. Furthermore, we found that care provision to a mother-in-law had an additional, negative association with mental health for female caregivers, as opposed to men. These findings suggest that more panel studies are needed to examine the correlates of mental health among middle-aged adults. © 2014 Elsevier Ltd.

Industrial clusters have attracted increasing attention as important locations of innovation. Therefore, several countries have started promotion policies for industrial clusters. However, there are few empirical studies on cluster policies. This paper examines the effects of the "Industrial Cluster Project" (ICP) in Japan on the R&D productivity of participants, using a unique dataset of 229 small firms, and discusses the conditions necessary for the effective organization of cluster policies. Different from former policy approaches, the ICP aims at building collaborative networks between universities and industries and supports the autonomous development of existing regional industries without direct intervention in the clustering process. Thus far, the ICP is similar to indirect support systems adopted by successful European clusters. Our estimation results suggest that participation in the cluster project alone does not affect R&D productivity. Moreover, research collaboration with a partner in the same cluster region decreases R&D productivity both in terms of the quantity and quality of patents. Therefore, in order to improve the R&D efficiency of local firms, it is also important to construct wide-range collaborative networks within and beyond the clusters, although most clusters focus on the network at a narrowly defined local level. However, cluster participants apply for more patents than others without reducing patent quality when they collaborate with national universities in the same cluster region. © 2010 Springer Science+Business Media, LLC.

It has been found that the pass-through of the exchange rate and import prices to domestic prices has weakened over time. The most recent research, however, shows that this trend may have been reversed. Recent studies have applied various time series methods to the Japanese data, and estimated responses of domestic prices to the exchange rate and import prices in different time periods. Those studies have found signs that pass-through has made an impressive comeback since the early 2000s. This paper reviews the most recent evidence and discusses its policy implications. I argue that the exchange rate has likely regained its status as an important transmission mechanism of monetary policy to domestic prices. © 2014 The Author.

Industrial clusters have attracted considerable attention worldwide for their expected contribution to regional innovation. Recently, policymakers in various countries have developed specific cluster policies. However, there exist few empirical studies on cluster policies. Focusing on the Industrial Cluster Project (ICP) in Japan initiated by the Ministry of Economy, Trade and Industry in 2001, we address two research questions on the support programs of the cluster policies: if the project participants who exploit various support programs are more successful in network formation within the cluster than others, and which kind of support program contributes to firm performance. We pay special attention to the differences between direct R&D support and indirect networking/coordination support. The estimation results, which are based on recent original survey data, suggest that cluster participants who exploit support programs (especially indirect support measures) expand the industry-university-government network after participating in the ICP. Moreover, we find that not every support program contributes to firm performance; firms should therefore select the program that is most aligned with their aims. Indirect support programs have an extensive and strong impact on output whereas direct R&D support has only a weak effect. © 2011 Elsevier B.V.
