Based on the data in the Japanese Science and Technology Indicators 2017 by the Ministry of Education, Culture, Sports, Science and Technology, the situation in which we are located and future possibilities are discussed.

Surface science had its beginning at the dawn of the human civilization and vacuum science in the 17^th century. Collaboration between them has begun in the late 19^th century and has grown in close manner in the field of science and technology since that. As an example of their collaboration, the author's work for 40 years is introduced.

The mechanism of gas release from the system in the process from ultrahigh vacuum to extreme-high vacuum was overviewed based on the basic evacuation model, quantitative outgassing measurement, and the examples using actual vacuum vessels. The main residual gas species after exposure to the atmosphere is water molecules adsorbed on the vessel wall. Accelerating thermal desorption of adsorbed molecules is the main role of baking. The gas species in the vacuum chamber that has been baked sufficiently is hydrogen molecules, and for extreme-high vacuum generation, a vacuum pumping system having a sufficient pumping speed for hydrogen is important. In the near future, it is highly expected that the extreme-high vacuum region will be a routine for researchers in surface science.

I became the Vice President of JVSS at the 1st general meeting in May and become the Chairman of the Industry-Academia cooperation committee. I would like to introduce the Industry-Academia cooperation of the two previous societies that I have actually worked on in setting up the Industry-Academia cooperation committee at the new society. I am hoping to advance as a new academic society through the Industry-Academia collaboration.
