MORITA KISEN K.K.

The flag’s outer blue bands appear broader than the others. Japanese publications from 1953 show a funnel M, but Yuyo Maru was recorded without it in March 1963 and with it in April 1965. Watt describes M1’s letter shape as wrong and its lower white band as wider. Rosanoski notes that the original NJK drawing’s V extended only through the second blue band and assumes a treatment like M135, while acknowledging that the correction is unclear.
