You're missing Hicho no Kata. If you're referring to what's commonly called the Sanshin no Kata as the "five basic kata", then yeah, they're not part of the Kihon Happo. If you're referring to the Torite no Gata as the "five basic kata", then they are (although, technically, the Torite no Gata are 10 kata, as each of the five are done on both the right and left sides). The Torite no Gata are a series of joint locking methods (Omote Gyaku, Omote Gyaku Tsuki, Ura Gyaku, Musha Dori, Muso Dori/Ganseki Nage,with variations depending on your teacher, as listed earlier in the thread), which, combined with the Moto Gata (three striking-based patterns, being Ichimonji no Kata, Hicho no Kata, and Jumonji no Kata) form the Kihon Happo (in basic terms, at least). The Sanshin/Shoshin Gogyo Gokei no Gata/Goshin no Kata are a series of five "elemental" named patterns, often learnt solo (although they are also trained with a partner in other forms of exploration), being namely Chi no Kata (Earth), Sui no Kata (Water), Ka no Kata (Fire, occasionally listed as "Hi no Kata), Fu no Kata (Wind), and Ku no Kata (Void).
