Rejoice!
No longer must you think to yourself "Damn, I really wish I knew who sang the B-side to Hana no inochi wa mijikai mono yo"! No more will you lament your ignorance as to who wrote the lyrics to Yoru no Akuma! You can, at any time you wish, find out the catalogue number for Igawa Ondo / Igawa Kouta!
Alright, maybe not so many people are curious about those things, but I'm quite happy to announce that I've compiled (what I believe to be) the first full* discography for Yoshiko Otowa, and it'll be a permanent fixture in the tabs bar at the top of my blog from now on. This is, as far as I know, the only list of its kind; no one website has a complete catalogue of every release she sang on. I've linked to YouTube recordings of all the songs that I could find, but some of these songs have never been uploaded to the internet. I own many of her records - and will buy more in the future - so I am actively working on uploading those missing tracks.
Her singing career lasted from the early 1950s to the mid-late 1970s (it's a little foggy when exactly she stopped recording music), so if you've got any interest in Japanese pop music from any point within that period, it might be worth checking some of this stuff out.
*This is still somewhat of a work in progress; her work is so obscure that I will be continually updating this list if/when I find more.
