I came across this particular Japanese website while surfing audioasylum.com. Have no idea what the Japanese writing is saying but the photos are enjoyable....
Some of the brands may be unfamiliar to those outside of Japan. As far as I know....
Lo-D = Hitachi
Exclusive = Pioneer's high-end line in Japan
A&D = Akai
Optonica = Sharp
Victor = JVC
Diatone = Mitsubishi
Trio = Kenwood
Esprit = Sony, forerunner of the ES line
