Karoff Japanese mid century mini bar

I found this interesting little cabinet at my local thrift store. I have no idea what it is supposed to be used for. The cabinet measures 14 1/4 inches high x 12 3/8 inches wide x 6 1/2 inches deep. The doors and sliding drawer work together, if you open one all three open together. They can not be opened or closed independently. the doors have openings for holding something. There are three small wooden dividers at the back of the cabinet that divide the space into four equal parts. The holders on the doors do not touch the dividers. The depth of the sliding drawer is 1 1/2 inches. The cabinet was made in Japan, as indicated by the sticker, but I don't know the manufacturer or when it was made. I would appreciate any help in identifying what type of cabinet this is and the manufacturer and approximate age. Thank you in advance for your help.
