Before the War between Japan and Russia, considering the need of millitary 
ship for wireless, Navy had founded the Wireless Researching Commitee in 
1900. Soon after that, in 1902, Professor Shunkichi Kimura from The Naval 
College went to Europe and America together with one naval officer to 
investigate the circumstances about the wireless.
Professor Kimura, who had already had some experiences from America, read 
Tesla's book about the high frequency alternating current, asked him for the 
explanation about the wireless and visited Tesla's laboratory at Manhattan. 
Tesla was 45 then and he had already started building of The World 
Broadcasting Tower at Wardenclyffe in Long Island and made the first step of 
realizing the "World System".
Tesla performed a fascinating demonstration of giant Tesla coil for the 
guest from the far away East. Comparing to power transmission without wire, 
Tesla said sneering that the wireless telegraphy was not at all such a great 
invention.
Kimura wrote an essay about that event and said this: "After my visiting 
Tesla's laboratory and seeing the demonstration of his giant Tesla coil, it 
could be described as a giant snake winding all around. That experience of 
demonstration made me understand the efficiency of the electrical resonance 
at once. Sneering at the wireless communication as a great invention, Tesla 
said that he realized the meaning of the wireless transmission of power and 
wireless electrical lighting. Maybe that would be realized sometimes in the 
future, but for the present moment it is not useful for our 
research".Tesla's opinion about the importance of the wireless the 
telegraphy is that it might be caused by Marconi's overtaking in the sense 
of making wireless before Tesla himself.
However that may be, through this reseach trabel, Kimura acquired confidence 
in himself that their technical attainment of wireless telegraphy was by no 
means inferior to that of West. So, having come back to Japan, he tried to 
develop unique Japanese system at his own. The result of this efforts was 
equipping the patrol ship "Mikasa" with wireless machine before the battle 
at the Japan Sea when "Mikasa" used it for sending information about the 
Russian Battle Fleet.

'Japan, on the other hand, had relied on the Marconi company to to equip its 
fleet, not directly but through a Japanese copy of the Marconi installation 
made by Professor Shunkichi Kimura, somewhat simplified to single 
transmission frequency and a plain aerial...'
