Company History

■1967
 Establishes Y.K. Kawahara Komuten, a general construction company.


■1987
 Establishes Kawahara Technical Research Co., Ltd.
 Starts to promote projects based on the concept of “Technomix”, or the consolidation of technologies from different industries,
 with an aim to reach beyond the realm of general construction and become a company involved with all areas of technology.


■1995
 Starts R&D on the crystallization of inorganic oxides.


■2004
 Starts R&D on energy conversion elements; establishes the R&D department.


■2008
 Starts R&D on inorganic EL, a next-generation luminescent material.


■2009
 Starts R&D on SOMA 107, a high-functioning advanced shielding material.


■2010
 Starts scrutinizing the radiation shielding capabilities and spectral properties of SOMA107.
 The gamma irradiation shielding rate of SOMA107 is measured at a public institution.
 The X irradiation shielding rate of SOMA107 is measured at SPring-8.
 The electron irradiation shielding rate of SOMA107 is measured at the Radiation Research Center of Osaka Prefecture University.
 The neutron irradiation shielding rate of SOMA107 is measured at S.H.I. Examination & Inspection, Ltd.
 Starts development of PPE (such as protective suits for radiation shielding and life-support systems) using SOMA107 as their main material.


■2011
 Tohoku earthquake and tsunami, and Fukushima nuclear disaster
