In March 1943, the new Butoku Kai changed the titles to Hanshi, Tasshi and Renshi (Senior Teacher), and the dan-i (qualification of rank) to a to-i system, with the fifth 'to' as the first dan level, the fourth 'to' as the second dan level, and so on to the first 'to' as the fifth dan, thus abolishing the sixth dan and those above it.
昭和18年（1943年）3月、新武徳会は称号を範士・達士・錬士とし、段位を等位制に改め、初段を五等、二段を四等～五段を一等として、六段以上の段位を廃止。
