Travel around Japan was heavily restricted by the Ashikaga shogunate during this rebellious era, but the Fuke sect managed to wrangle a rare exemption from the Shogun, since their spiritual practice demanded a mendicant lifestyle of constant pilgrimage, meditative shakuhachi playing and begging for alms (one famous song reflects this mendicant tradition, "Hi fu mi, hachi gaeshi", "One two three, pass the alms bowl"). They persuaded the Shogun to give them "exclusive rights" to play the instrument and travel about the country as they pleased. In return, some were required to spy for the shogunate, which (quickly recognizing the utility of the ruse) also began dispatching their own spies on secret missions in the disguise of komusō.[3]Ninja and ronin (masterless samurai) were also known to travel in the guise of komusō to avoid official scrutiny of their presence or intentions in a province.
Once this became common knowledge, travelers wearing the komusō outfit became subject to closer inspection, especially in restive and disputed areas. Several particularly difficult honkyoku pieces, e.g., Shika no tone, became well known as "tests": if a suspicious komusō was challenged to play one of the test pieces and was able to reproduce it in the authentic suizen manner, he was accepted as an actual Fuke. If he was unable, or if he refused, he was assumed to be a spy and would likely be immediately arrested.
