“It made me feel so happy that the day started in such a pleasant way,” smiles a Japanese woman in her late teens. As most Japanese spend a considerable amount of time commuting to work and school, this may be the best time to send a message.

Your birthday wishes will bring her a smile and set the stage for a lovely day ahead.
