31 Kumi Jo Aikijo Bukiwaza

The 31 Kumi Jo (Kumijo) is the partner practice for the Aikido 31 Jo Kata. The 31 Kumi Jo (Kumijo) was organised by Morihiro Saito Sensei who learned the 31 Jo Kata from O Sensei during his 25-year service and tutelage. By the way, as far as this article is concerned, we will spell ‘Kumi Jo’ and ‘Kumijo’ interchangeably, because both spellings are correct.

Osensei was working on the Aikijo, Aikiken, and Aikido during his retirement in Iwama. Saito Sensei was Osensei’s assistant during that period in Iwama Japan.

Saito Sensei became the guardian of the Aiki Shrine in Iwama and vowed that Iwama Style or Iwama Aikido will always be true to Osensei’s Aikido.

Saito Sensei put together 31 Jo moves that can be learned and passed on to the next generation.

These 31 Jo Kata can be practised with a partner. When practised with a partner the 31 Jo Kata are known as ’31 Kumi Jo’.

Here are 7 ways to do the 31 Kumi Jo, I hope this article and page helps you with your 31 Kumi Jo.
