English
I.
The hat over both eyes
Obstructs the Moon from one's vision, oh
The smile held back, oh
Whilst steering the ship, oh.
II.
The seagulls of the sea
If you inquire at the appropriate time, oh
I find myself among the birds, oh
As we heed to the waves, oh.
III.
Telling my daughter
Not to fall for any students of mine, oh
Should you hear the cacophony of the signal guns, oh
It is the sound of new widows, oh.
IV.
The waist dagger
Is exquisitely suspended, oh
A charm equivalent to insect repellant, oh
To women, oh.
V.
The inspection tour's arrangements
The Bugle blares for us to hear, oh
Homesickness takes hold, oh
And I am constantly reminded of it, oh.
VI.
The gust of a Spring breeze,
Does not scatter the Cherry Blossoms, oh
At least during exams, oh
Until their end, oh.
VII.
Examinations come to an end,
The holiday is within sight, oh
The swimming drills, oh
Where all for nought, oh.
