6th Dan. Good to hear there's sensei teaching. 'Cause there are some youngsters proclaim they are senpai/sensei (which they learnt for less than a year, or watch in DVD/Youtube/book). Yeah...undisciplined. Finland's Kendo is recognized by FIK (International Kendo Federation) under EKF (European Kendo Fed.) So you not have to worry about it.

Usually Kendoka with 3rd-Dan above are called "sensei". However, some prefer at "4th Dan".

Hmm...That's true. Beginners are put that way so they can choose which sword arts they are more interested in We had 3 aessions week. You dont have to worry about your toe. Usually we dont use toes to move. "ashi-sabaki" is more on sliding. Example, lazy way of people walking - they dont lift their feet when they walk.get it?.LoL. I remember my first time, i was told to do ~2hours of 'ashi sabaki'. Beginner (sometimes) tend to get blister on the bottom of your feet.

Second, if you swing hours with shinai during your training. You'll get blisters on your hands. Do ask your sensei about your blisters. They can indicates your wrong way of holding the sword. Then, you should ask which position of blisters on your hand you should get/see for the correct cut (or swing). YES. We must get blisters on our hand - which is the left hand. LOL.
