Hello,
I am a student of Mehmet Sıtkı Doğu who leads Iwama Ryu Turkey. Thanks for mentioning our web site on the forums. We have keiko everyday except sunday, 07:00-08:00 in the morning and 19:30-21:30 evenings and 11:00-12:30 on saturdays. There is bukiwaza (aikiken and aikijo) training in both morning and evening keiko.
Btw, dear Steffen, i will make sure my instructor receives your hi.
