Beatles: Help ?

I own (just found it in deep storage) a boxed set of Toshiba EMI Beatle albums. 12 to be exact. The box is entirely in Japanese. Each album has cellophane sleeves for the records. The box is blue 3/4 quarters of the way up in the front with a white flip cover at the top. All lettering on the top is in Japanese. EMI is printed on the individual albums, as well as Apple on many of them. The back of the box is entirely blue. I purchased this baby in 1978ish? 'twas expensive at the time, but I can't, for the life of me, remember where and how much I

paid for it. Was purchased at a Hi End audio store. Anybody have a clue what I have? All the albums have not been played. A stylus has never touched them. thanks in advance.
