For three years, from January 1914 until his move to England in 1917, Kosaku Yamada actively worked as a pioneer of Western music in Japan, establishing orchestras and performing his own piano works at 'Yamada Abends'. In his private life, he married Ikuko Nagai in 1915 (though the marriage was not officially registered), but they later broke up. In November 1916, he married his childhood friend Kikuo Murakami (Isoyo Kawai). He led a fulfilling life, with his eldest daughter Misa being born in April of the following year.

Geshun (Welcoming Spring), composed in December 1916, was originally conceived as the tenth piece of Petit Poème 'A Page from a Diary'. However, the composer deleted the words 'No. 10', and the current tenth piece, Joya (New Year's Eve), was newly composed. Although no record of the composer's own premiere remains, Geshun is included in his self-selected piano collection 'Oto no Nagare' (Flow of Sound), published by Oliver Ditson Company in Boston. The entire piece is very short, consisting of only 24 measures. The beginning of the piece is marked by significant changes in meter, the appearance of fragmentary motifs, and frequent double stops. However, the melody in the right hand that appears from measure 9 onwards is written in a traditional Japanese pentatonic scale, making it very melodic and adding nuance to the piece.
