English translation
The day my faint first love vanished The rain came down so gently Concealed by my umbrella on the pier Staring out, I cried I was so childish, my chest burning My longing continued -- that person's name was Sensei, Sensei, it was my teacherI cried out at the top of my voice To the ferryboat departing far off A white lighthouse like a painting Rising out of the rain beating down With a sadness no one can give a name The pain in my chest -- that person's name was Sensei, Sensei, it was my teacher The happiness of a heart in love Teaching my gently -- that person's name was Sensei, Sensei, it was my teacher
