Over 30 years experience & achievement in Pulsed Power Technology

Concept

PPJ will support the development of the science and technology. Additionally, We will contribute to protect all of the global environment and enrich people’s livings by offering the technology with safety generation and control of the extreme situation; Pulsed Power.

Corporate Principles

  • We cooperate with research laboratories such as universities and national research institutes. We will systematically do the Maintenance, the development, and the succession of the pulsed power technology in our country.
  • We always try to study, and to create new social needs in development and the improvement of the technology.
  • We try to collect overseas technical intelligence, and always aim at the top technological level of the world.

Message

I have studied pulse power technology at Nagaoka University of Technology, and have developed a large number of pulsed power systems for many research institutions.
Our company is young and small, but We can provide the excellent technical service which specialized in the further state-of-the-art pulse power technology.
Our hope is that we contribute to development of technology with the clear technology based on the experience and the achievement for over 30 years of the high voltage, large current pulsed power devepolment.
Moreover, it cooperated with the universities and the research institutes engaged in research of pulse power technology, and I aim at becoming a pivotal organization which achieves systematically maintenance, development and  succession of the pulse power technology in Japan.
