Business establishment: in 1918 at age 23

Now that business was picking up and Konosuke had money to invest, he rented a two-story home and launched Matsushita Electric Housewares Manufacturing Works that was to become Panasonic.
With this larger workshop on the ground floor, Konosuke was able to expand his production to include an innovative attachment plug and a two-way socket, both of which he designed himself.
These new products proved immensely popular, earning the company a reputation for high quality at low prices. And by 1922, Konosuke had to build a new factory and office to house his growing business.
