From hidden treasures like the Shinfukan Dojo in Marseille, France and modern luxuries like the Shinjuku Cosmic Centre in Tokyo, to the lineage significant floors of the Musashi Dojo in Ohara, and our current hombu at the Japanese Canadian Cultural Center in Toronto; the art may be the same, but the environment each have their own uniqueness.
An Iaido friend once told me to let my emotions flow into my training.
When you feel happy, do happy Iai. When you feel upset, do angry Iai. Let your Chi/Ki carry these feelings into your movements until you are in balance. This will bring life into your Iai.When entering an unfamiliar dojo, there is a lot you can learn from basic sensory input (sights, sounds, smells), but don't forget the feelings to come about subconsciously. Let yourself forget about technical differences and styles, and experience the training with an open mind and heart. There's no telling how much your performance can change.
