Japanese Painting in Hanamasa

I found this painting in Hanamasa Restaurant,Giant Mall,Point Square.TB Simatupang street.  On the picture there is figure of girl playing Japanese Guitar.  She is learning and read the music book in front of Her.  Dress That she wearing called Yukata.  The Japanese Painting style is little different from Chinese Painting even look the same.  Chinese paintings drawn with a lot more style curved brush on each corner so that the robe or gown and shawl she used appear to form look a circle or wave.  I dont know who made this painting, on the top left, there is a word of Japanese called Kanji, and I can not translate it..Maybe you can visit Hanamasa restaurant and watching so seriously to understand that Kanji. thanks
