Yoko Kanno wrote the music of the Japanese estate agency HouseMate campaign.
The full version of the music, which is an untitled 0:50 orchestral piano piece, is available for listening on the Grand Funk Inc. official website.
Interesting fact, the last music Kanno wrote for Grand Func Inc. was at the very beginning of the year 2013 for Japan Tabacco Inc., meanwhile she seemed to have worked for Piano Inc. only.
The campaign started around December 11, 2013. The first commercial is entitled「まごころ。父親」(“Devotion: Father”):
The second one is entitled「まごころ。未来」(“Devotion: Future”):
The full music is available on the Piano Inc. sounds page.
