Johanna Kustannus Oy (Ltd) has been the name of two Finnish record labels. Atte Blom has been a founding member for both companies, and Pekka Aarnio has also been involved with both. The first company using the name used the sublabel Johanna, while the second one used Pyramid and Megamania.
The first Johanna Publishing started in 1978 with the publication of Juice Leskinen's, Dave Lindholm's and Kari Peitsamo's lyrics books. When Love Records went bankrupt in 1979, Johanna Kustannus began publishing records. A majority of the bands signed with Love Records transferred over to Johanna Kustannus.
At first the company's name was Musiikki- ja kirjatoimisto P. Karhu, and the company also made a few releases under the sublabel Karhu. The first single released under the label Johanna was "Lontoon skidit" (JHNS 101) by Ratsia, and the first album "Kohdusta hautaan" (JHN 2001) by Tuomari Nurmio ja Köyhien Ystävät. At this time Johanna's releases were being published by Love Kustannus Oy. Johanna Kustannus began publishing its releases in 1981, and in 1982 the company was renamed to Johanna Kustannus Oy. Johanna Records released approximately 40 records in 1981.
