This is a small point. There is no plural in Japanese. You would say one kata or two kata. You would not say two katas. You don’t add the English letter “s” to Japanese words to make them plural.
Also I would say that there are two sensei, not two senseis. Or I will teach two waza, not two wazas. Or there are two dojo in Kingston , not two dojos in Kingston. Or I would refer to the five Pinan kata rather than the five Pinan katas. So no plural in Japanese.
