I found the answers and wanted to share them. There is only one kiyai per Bo Kata in this style. In the katas identified above, those Kiyais are as follows: (1) Sueyoshi-No-Kon: Last move of the kata (i.e., the strike in kibadachi depicted on page 7, column 2, row 2 of the reference pictures); (2) Sakugawa-No-Kon: On the second of the two double tsukis (i.e., in the strike depicted on page 17, column 2, first row of that column of the reference pictures); (3) Shirotaru-No-Kon: On the landing after the jump as the practitioner executes gedan level counter attack (i.e., at the point depicted on page 16, column 1, row 3 of the reference pictures); and (4) Matsukase-No-Kon: At the flying ushiro tsuki(i.e., at the point depicted on page 16, column 1, row 2 of the reference pictures).
