Wado-Ryu Hironori   Otsuka   was   one   of   the   first   students   of   Gichin   Funakoshi.   As   a   student   of   Jiu   Jitsu   probably he   found   his   way   to   Funakoshi   by   Judo   master   Jiro   Kano,   who   was   highly   interest   in   Karate.   Otsuka got   master   degree   in   short   time.   After   caming   in   contact   with   Kenwa   Mabuni   he   did   start   to   study Shito   Ryu.   Most   of   the   Wado   Ryu   Kata   are   based   on   Shito   Ryu.   So   he   took   the   5   Heian   Kata   under their okinawan name Pinan. The Naihanchi is identical to Naihanchin Shodan and far away to be the old original Naihanchi. Same   is   for   Bassai   which   is   Bassai   Dai.   The   Kushanku   is   identical   to   Kosokun   Dai   but   also   includes some techniques of Kanku Dai. Seishan is identical to Hangetsu. Chinto is similar to Shito Ryu Chinto and is known as the highest Kata of Wado Ryu. This was the fundamental curriculum of Kata of the style. More Kata has been added later. As   Otsuka   made   Wado   Ryu   public   it   was   highly   welcome   in   Japan.   Because   Otsuka   was   Japan, while Funakoshi and Mabuni came from Okinawa. So it was a homegame. Wado Ryu is close to real combat situations. Especially Tai Sabaki plays a main role. The   fact   that   the   defense   against   knife   attack   is   an   important   part   can   make   as   think   that   street fighting was a theme in Otsuka's work. In   his   time   it   was   not   common   to   be   attacked   on   the   road   by   traditinal   weapons   like   sword,   Bo, Tonfa, Sai. Much   more   probably   was   the   attack   with   a   knife.   In   fact   a   knife   is   a   dangerous   weapon.   Easy   to carry and difficult to defeat. Like    Sokon    Matsumura    the    legendary    grandmaster    of    Shuri-te,    Otsuka    may    have    found    the conclusion that Tai Sabaki is a good way to stand out of the way of any attack. So Wado Ryu seems to be close to the ideas of the okinawan roots. This   makes   Wado   Ryu   less   attractiv   on   the   sportive   scene.   And   in   fact   in   Kata   competition   it's   plays no role. But for the value of the style this has no meaning. The   interest   on   the   old   way   is   maybe   the   reason   why   some   Wado   Ryu   masters   are   interest   in   old Kata which not part of Wado Ryu, like Happoren or Rokkishu. Hironori   Otsuka   changed   the   Kata   of   Wado-Ryu   based   on   his   studies   of   Shotokan   teached   by   Gichin Funakoshi and the Shito-Ryu of Kenwa Mabuni. Though the influence of Shito-Ryu is more visible. In   the   beginning   the   Pinan   Kata,   the   Naifanchin   (Shodan),   the   Seishan,   Kushanku   an   Chinto   was included in the style. More   Kata   has   been   added   later.   In   present   time   some   schools   using   more   Kata.   Some   do Suparimpei. Bassai The Kata is similar to the Shito-Ryu Version. Only the end with Mikazuki Geri, Kosa Uke and the following Yama zukis we find in the Shotokan version Chinto The difference to the Shito-Ryu version is only by the performance of the techniques Jion This Jion is nearly identical the version of Shito-Ryu. But in Wado Ryu style a Gyaku Age Uke has been added. So we see the combination Age Uke, Gyaku Age Uke, Choku zuki instead for Age Uke, Gyaku zuki Jitte Jitte is also in mainpart identical to the Shito-Ryu version. Just the beginning is more similiar to the Shotokan Jitte Kushanku The Kushanku is close to the Kosokun Dai of Shito-Ryu. So it's not to compare with Chantanyara Kushanku. But some movements are done on the way of Shotokan Kanku Dai Naihanchi The Naihanchi ist close to the Naifanchin Shodan. But in some parts, which is especially to see in the combination with Uraken Uchi, it's changed Niseishi The Kata is nearly identical with the Nijushiho of Shotokan. Just the Age Uke with following Gykau Tate Empi is done straight direction instead of the sidewise version of Shotokan Pinan Shodan The Pinan Kata of Wado-Ryu are similiar to the Heian Kata of Shito-Ryu. The differences are less and mainly to see in the stances and movements of the legs. Also the Yoko Uke and Shuto Uke will be done in Jodan area Identical to Shito Ryu Heian Shodan (Shotokan Heian Nidan) Pinan Nidan Identical to Shito Ryu Heian Nidan (Shotokan Heian Shodan) Pinan Sandan Identical to Shito Ryu Heian Sandan Pinan Yondan Identical to Shito Ryu Heian Yondan Pinan Godan Identical to Shito Ryu Heian Godan Rohai This Rohai is identical with the Rohai Shodan of Shito-Ryu Seishan There are nearly no differences between this Seishan and the Hangetsu of Shotokan. It's only the performance of the techniques and more movements done slowy Wanshu The only difference between Wansu and Shotokan Kata Empi is, that after the Gyaku zuki in Kosa Dachi instead for the Ushiro Gedan Barai a Gedan Barai in Zenkutsu Dachi will be done in the same direction as the Gyaku zuki before.
