Romances of Old Japan: Rendered into English from Japanese Sources

His old widowed mother would not die happy unless he were rehabilitated, and to this end he knew that she and his faithful wife, O Yumi, prayed daily before the family shrine.
How often had he racked his brains to find some way by which it were possible to prove his unchanging fidelity to Shusen; for the true big-hearted fellow never resented his punishment, but staunchly believed that the ties which bound him to his lord were in no wise annulled by the separation.
At last the long-awaited opportunity had come. In obedience to the mandate of the Shogun Ieyasu that the territorial nobles should reside in his newly established capital of Yedo during six months of the year, the Daimio of Tokushima proceeded to Yedo accompanied by a large retinue of samurai, amongst whom were his chief retainers, the rivals Shusen Sakurai and Gunbei Onota.
Like a faithful watchdog, alert and anxious, jurobei had followed Shusen at a distance, unwilling to let him out of his sight at this critical time, for Gunbei Onota was the sworn enemy of Shusen Sakurai. Bitter envy of his rival's popularity, and especially of his senior rank in the Daimio's service, had always rankled in the contemptible Gunbei's mind. For years he had planned to supplant him, and Jurobei knew through traitors that the honest vigilance of his master had recently thwarted Gunbei in some of his base schemes, and that the latter had vowed immediate vengeance.
Jurobei's soul burned within him as this sequence of thoughts rushed through his brain. The tempest that whirled round him seemed to be in harmony with the emotions that surged in tumult through his heart.
More than ever did it devolve on him to see that his master was properly safeguarded. To do this successfully he must once more become his retainer. So Jurobei with vehement resolution clenched his hands over the handle of his umbrella and rushed onwards.
Now it happened that same night that Gunbei, in a sudden fit of jealous rage and chagrin, knowing that his rival was on duty at the Daimio's Palace, and that he would probably return alone after night-fall, ordered two of his men to proceed to Shusen's house and to waylay and murder Shusen on his road home. Once and for all he would remove Shusen Sakurai from his path.
