'Himawari no Yakusoku' (Promise of Sunflower) is Motohiro Hata's 17th single. It is the theme song for the Japanese animated film 'STAND BY ME Doraemon,' released in August 2014. It continues to be loved by a wide range of generations and is sung at events such as graduation ceremonies and weddings.

In the intro, which begins with an acoustic guitar, pay careful attention to the rests (lift your fingers precisely and feel the eighth-note rests). Ensure that the length of the rests at [A] is also not ambiguous. Throughout the piece, feel the 8-beat rhythm and play with a rich, singing quality. Be mindful of the count, as the time signature changes to 2/4 one measure before [C] and returns to 4/4 at [C]. At [C], the right hand features many ties; feeling the downbeat with the left hand's quarter-note pulse will help you play this section successfully. Practicing without the ties is also recommended.
