The Way of the warrior (bushido) is to be found in dying. - Yamamoto Tsunetomo

Meditation on inevitable death should be performed daily.
Every day when one’s body and mind are at peace, one should
meditate upon being ripped apart by arrows, rifles, spears and
swords, being carried away by surging waves, being thrown into
the midst of a great fire, being struck by lightning, being shaken
to death by a great earthquake, falling from thousand-foot cliffs,
dying of disease or committing seppuku at the death of one’s
master. And every day without fail one should consider himself
as dead.

Victory and defeat are matters of the temporary force of circumstances. The way of avoiding shame is different. It is simply in death.

Men of high and low status, clever men, and artistic men all vie to exhibit their merit as loyal servants, but become limp and craven when it comes to actually sacrificing their lives when calamity strikes. This is inexcusable behavior indeed.
