 a plurality of suction units that sucks and discharges any torn Japanese paper tapes to an outside; and   a plurality of storage tanks that stores any torn Japanese paper tapes discharged by each of the suction units.   
     
     
         6 . The Japanese paper yarn manufacturing device according to  claim 1 , wherein each of the yarn processing device units is a twisting device unit or a covering device unit. 
     
     
         7 . The Japanese paper yarn manufacturing device according to  claim 1 , wherein a plurality of the yarn processing device units includes a steam generator unit that applies steam into contact with each of the Japanese paper tapes or each of the Japanese paper yarns. 
     
     
         8 . The Japanese paper yarn manufacturing device according to  claim 1 , further comprising a plurality of yarn breakage detectors that detects breakage of the Japanese paper tapes or the Japanese paper yarns. 
     
     
         9 . A Japanese paper yarn manufacturing device comprising:
 a Japanese paper roll that is obtained by winding a long Japanese paper sheet in the roll shape;   a slitter that slits the Japanese paper sheet fed out from the Japanese paper roll into a plurality of Japanese paper tapes each having a narrow width in a feeding direction;   a distributing section provided with a plurality of tubes each having an inner diameter that allows each of the slit Japanese paper tapes to pass through; and   a plurality of yarn processing device units that processes the Japanese paper tapes distributed by the tubes of the distributing section into a plurality of Japanese paper yarns,   wherein an installation position of the slitter is higher than a Japanese paper tape supply position to each of the yarn processing device units, and an inclination angle of each tube of the distributing section is at a depression angle of 20 to 60 degrees.   
     
     
         10 . The Japanese paper yarn manufacturing device according to  claim 9 , wherein in the distributing section, one ends of the tubes are bundled and each of the other ends is provided in each of the yarn processing device units. 
     
     
         11 . The Japanese paper yarn manufacturing device according to  claim 9 , wherein the air flow section includes a plurality of nozzles each provided at an inlet of each of the tubes toward an inside the tube and one or more pressurizing devices that send compressed air to each of the nozzles. 
     
     
         12 . The Japanese paper yarn manufacturing device according to  claim 9 , wherein the air flow section includes a plurality of suction members each provided at an outlet of each of the tubes so as to suck air inside the tube and one or more decompression devices that suck air through each of the suction members. 
     
     
         13 . The Japanese paper yarn manufacturing device according to  claim 9 , further comprising:
 a plurality of suction units that sucks and discharges any torn Japanese paper tapes to an outside; and   a plurality of storage tanks that stores any torn Japanese paper tapes discharged by each of the suction units.   
     
     
         14 . The Japanese paper yarn manufacturing device according to  claim 9 , wherein each of the yarn processing device units is a twisting device unit or a covering device unit. 
     
     
         15 . The Japanese paper yarn manufacturing device according to  claim 9 , wherein a plurality of the yarn processing device units includes a steam generator unit that applies steam into contact with each of the Japanese paper tapes or each of the Japanese paper yarns. 
     
     
         16 . The Japanese paper yarn manufacturing device according to  claim 9 , further comprising a plurality of yarn breakage detectors that detects breakage of the Japanese paper tapes or the Japanese paper yarns.
