One of the main themes of the Research Task Force for ICT Tools on Telework is to master existing ICT tools both in our research activities and in our daily life. Although it is too early to validate the effectiveness of ICT tools for the huge earthquake in Northern Japan, an overview it still important. The function and the importance of ICT tools have changed a lot since the Great Hanshin-Awaji Earthquake occurred in 1995. This paper reports the kinds of ICT tools used and their effectiveness when the 3.11 Earthquake happened, focusing on the safety confirmation of family and work members. In the immediate aftermath of a large quake, to know "the size and seismic center of the earthquake", "damage in the local area or transportation conditions", and "information about the well-being of family" is needed. How did mobile phone applications, such as phone call, One-Seg function or e-mail, and communication network such as internet or intranet work on the day? Members will reflect on each experience.

The Tohoku Earthquake that caused catastrophic damages on North East Coast areas has given immeasurable impacts on Japanese people, society, and the economy. The influences were not only direct ones due to the tsunamis but also indirect ones such as; the inference on agricultures, stock farming, and fishing, caused by radioactive contaminations, power shaving quotas due to shortage of electricity by nuclear power plants shut down, the suffers of export industries due to rapid rise of the yen, and the overseas transfer of productions. Repeated natural disasters in the last decades have raised importance of Business Continuity Plan (BCP), and from this point of view Telework has been attracting attentions. After the earthquake, in the east Japan area, the disaster gave huge inference widely. Rotation power supply cut was conducted against shortage of electricity, public transport was disturbed and social and economic confusion was caused due to radiation contamination. Against all these unforeseen problems, to keep employees safeties and solve commutation problems, companies were forced to cope with stand by or work at home with Telework method. The Telework is now highlighted from the point of BCP and power saving. In this report, through the authors experience and visit to Tohoku, how Telework functioned just after the earthquake will be explained, and expectation and prospects of Telework will be discussed.

This paper reports the results of "a survey about telework at East Japan great earthquake disaster and the rolling blackouts of March and BCP (business continuation plan) for the well-informed people about telework" carried out by the study group about "BCP and Telework" of Japan Telework Society. The people and association with the connection for telework as well as members of this Society were asked for the investigation cooperation. The survey was carried out via the internet from April to June, 2011. The count object is 44 people, and the people who did telework at the earthquake disaster and rolling blackouts was 14 people, among which 11 people were able to perform more than 70% of normal duties by telework. The secret to telework well was reported "being always used to a telework" by 10 people.

The medium and small-sized business suffered big damage from East Japan great earthquake. This disaster had a big influence on the world economy as well as Japanese. The necessity of development and the review of the business continuity plan is increasing for not only large companies but also medium and small-sized enterprises. One of the solutions includes dispersion placement of employee, and it can be realized by telework. It became clear that the strategic enforcement of resources with telework was very important from the point of view of their business continuity.

Today teleworking is increasing rapidly, but the shift to working at home from commuting to and from the office everyday may increase an environmental burden by using inefficient equipments at home such as air conditioners. In order to calculate and compare life cycle CO_2 emissions between different work styles, we set three work style scenarios, working at office, using the telework center in worker's neighborhood and working at home. Ahead of calculating, we measured life cycle CO_2 emission of telework centers in Kanto region, Japan, because there is no inventory data of the telework center. In this life cycle CO_2, We also considered CO_2 emissions from commuting and the rebound effects attributed to the increased leisure time. Additionally, there are great differences in the each work styles among individuals, such as commuting time or energy consumption. So we did an uncertainty analysis with Monte Carlo simulation, then we found the high contribution factors of each scenarios. As a result, we found if a telework center or a conventional office is used efficiently, their CO_2 emissions become same level as working at home.

An Ultra- or Meta-Realistic Telework Communication System is one which allows people outside the office to experience exactly the same emotional environment as those physically present, enabling a communal atmosphere. This will allow us to live wherever we wish, irrespective of the work we perform, and in this way transform not only how we work but also our very way of life. In study 1 , I tried to put in order various ways of psychological estimation in this Ultra-&Meta- Realistic Telework Communication System. Also people, I tried to meet and talk people as a first step concerning Telework aiming to fix the frame to construct a mental model of the user. In study 2, I conducted two basic survey researches on the construction of an intuitive user interface (intuitive operation). The results suggest using a combination of one or more means, including gesture, voice, or brain interface.
