Aiwa is now a brand owned by the Sony Corporation,

Originally called Tokyo Tsushin Kogyo (Tokyo Telecommunications Engineering Company), Sony’s roots go back over half a century to 1946 when it was founded by Masaru Ibuka and Akio Morita. In the crippled post-war Japanese economy Ibuka and Morita made their living repairing radios and manufacturing small numbers of voltmeters whilst looking to develop a future in designing and manufacturing new electronics. Perhaps surprisingly, their first electronic innovation was an automatic rice cooker. Its success was limited but it was the first in a long line of innovations which continue today.
