Foreign tourists inbound Japan have been over 24 millions in 2016. It was the result of the policy of “Tourism-oriented nation” which is pushed by Japanese Government. And the aim is increasing foreign tourists to 40 million by 2020 Olympic Game in Tokyo - “Inbound Japan” - the project of cooperation between state and people. It is not so surprised to the leading countries in tourism of the world, but that means foreign tourists will be over 6 times less than a decade from 2012 after the Great Eastern Japan Earthquake. It will boost GDP in macro economy extremely, but meanwhile, there are problems at the spots and local areas. We discuss the relations and gaps between foreign tourists and local residents as one of global issues and propose our solution for how to adjust both benefits, establish and keep a partnership relation for the mutual interest among respective parts concerned.

Wellness is usually used to focus on the activities of young or middle aged generation. But, in the extremely aged society like Japan and other developed countries, we must pay much more attention to the wellness of aged person. This study discusses the issue with partnership marketing.

The aging of society is speeding up in Japan. Although over 30 millions of aged persons in Japan are not good at using up-to-date tools like the internet for their daily life, they are well-off and have attractive purchasing power than younger generation. It is very import task how to approach them to sell goods, provide services through the internet. The issue seems to Japan just now, but will be the large and urgent task to Korea, to China in near future. We discuss the measures on the view of partnership marketing.

In order to overcome the recrystallization embrittlement and irradiation embrittlement of Mo, which are major problems for its fusion applications, internally nitrided Mo alloys were prepared by a novel multi-step internal nitriding. Neutron irradiation was performed in the Japan Material Testing Reactor (JMTR). After irradiation, nitrided Mo alloys exhibited ower ductile-brittle transition temperature than irradiated TZM. These results suggested that multi-step internal nitriding was effective to the improvement in the embrittlement by irradiation. Transmission electron microscope observation revealed that TiN particles precipitated by nitriding acted as a sink for irradiation-induced defects.

WC-TiC-TaC binderless cemented carbide was oxidized under low partial pressure of oxygen (50ppm) at 873K for 1 to 20 h. Surface roughness was measured using atomic force microscope, and effect of TiC amount on oxidation behavior of the carbide was investigated. WC phase was oxidized more easily than WC-TiC-TaC solid solution phase. With an increase in TiC amount, WC-TiC-TaC phase increased and the oxidation resistance of the carbide increased.

The effect of TiC content on oxidation behavior of the sintered WC-TiC-TaC alloys with 2 mass% TaC and different TiC amounts of 3-45 mass% was investigated through oxidation tests in air at 973K. As a result of the tests, it was revealed that with increasing TiC content in the alloys, mass changes caused by oxidation and thickness of the scale decreased. Thus, it is considered that the main component of the scales changed gradually from to with increasing TiC content in the alloys, and oxygen diffusion through the scale to the alloys was inhibited gradually.

We have studied the effect of C/Ti atomic ratio of TiCx (x=0.5, 0.75 and 1.0) raw powder on the properties of the Ti-Mo-WTiC sintered hard alloy. The decrease of C/Ti atomic ratio accelerated the densification in the sintering process. The hardness was remarkably improved up to 1350HV with decreasing the C/Ti atomic ratio because of increase of TiCx phase volume content and its fine dispersion. From the results of electro-chemical tests in acid and 3% NaCl solutions, it was obvious that every alloy had excellent corrosion resistance, which meant about 200 times better than that of WC-Co cemented carbide.
