The article discusses how Japan's security environment is deteriorating and maritime safety controversies. Topics discussed include China's relations with its neighbors and strengthening of Japan's military presence in the southwestern region and the views of China's military expert Yin Zhuo on efforts of Japanese government to revise the Pacifist Constitution.

Muonium is a bound state composed of an antimuon and an electron, and it constitutes a hydrogenlike atom. Because of the absence of the hadronic matter in the bound state, the muonium is a useful probe to explore new physics being free from the hadronic uncertainties. The process of the muonium-to-antimuonium transition is considered to be effective to identify fundamental interactions which relate to the lepton flavor and lepton number violation. New experiments are being planned at J-PARC in Japan and CSNS in China, and it is expected to attract more attention in the near future. In this paper, we will study what kind of model can be verified in the next generation of the muonium-to-antimuonium transition search experiments while escaping the limitations from other experiments. Though the transition probability is strongly suppressed by the lepton flavor conservation in the standard model, it can be much larger by the exchanges of neutral and doubly charged bosons, and by box loop diagrams in new physics beyond the standard model. We study the neutrino models with heavy Majorana neutrinos at TeV scale, a type-II seesaw model, left-right models, and models for radiative neutrino masses such as the Zee-Babu model in particular, in addition to other possible models to induce the sizable transition probability, which can be tested in the forthcoming experiments.

Abstract: In this paper, we derive a new class of flexible threshold asymmetric Generalized Autoregression Conditional Heteroskedasticity (GARCH) models. We use this tool for analysis and modeling of the properties that are apparent in many financial time series. In general, the transmission of volatility in the stock market is time-varying, nonlinear, and asymmetric with respect to both positive and negative results. Given this fact, we adopt the method of fuzzy logic systems to modify the threshold values for an asymmetric GARCH model. Our simulations use stock market data from the Taiwan weighted index (Taiwan), the Nikkei 225 index (Japan), and the Hang Seng index (Hong Kong) to illustrate the performance of our proposed method. From the simulation results, we have determined that the forecasting of volatility performance is significantly improved if the leverage effect of clustering is considered along with the use of expert knowledge enabled by the GARCH model.

Abstract: The People''s Republic of China is one of the world''s most popular tourist destinations. This paper reviews the development of the Chinese inbound tourism industry after the cultural revolution and analyses tourist flows from Japan, which is the most important short-haul inbound market for China. Box-Jenkins univariate time series analysis facilitates an understanding of tourist arrival patterns in inbound tourism for China from Japan for the period 1986–2000. Tests for stationarity of tourist arrivals time series are also conducted. [Copyright &y& Elsevier]

Discusses the controversy between Japan and China over the Diaoyu Islands. Discovery of oil and natural gas deposits off the islands; Negotiation of signing of treaty of peace and friendship between countries; Japans' construction of beacon tower on one of the islets; Japanese adoption of 1996 defense white paper.

The author reports on the 2012 summit meeting between China, Japan, and South Korea wherein a decision was made by the countries' state leaders to begin talks on introducing a Free Trade Area within the year. Regional trade between the countries increased to 690 billion U.S. dollars in 2011 according to a Chinese Foreign Ministry white paper. Differences and disputes reportedly remain among the three countries due to political situations in East Asia despite their strong economic ties.

Discusses how cardboard is in short supply in Japan. In Japan, China's insatiable demand for raw materials is now endangering the most vital commodity in retailing: the cardboard box. Once blamed for exporting deflation to Japan, China is now charged with causing the recent surge in the prices of nickel, plywood and other commodities. Japanese cardboard-makers are reluctant to match these prices and have opted to lower production instead. Still, after another hike in procurement costs last autumn, the Japan Corrugated Association, the industry body, called on its members to start raising cardboard-box prices. Local governments, which collect waste cardboard along with other sorts of rubbish, are also affected: they find private collectors now swipe the stuff before they arrive.
