While I have been doing Aikidō for around ten years, this has not been a continuous process, I practiced in some place, stopped, moved elsewhere and started again. To make things even more confusing, nearly each dōjo I practiced was in a different organisation, consider:

• The Aïkidō Club des Eaux-Vives, where I started, is part of the Union Suisse d’Aïkidō. The dōjo follows the teachings of Hirokazu Kobayashi.
• The Aïkido Club Meyrin, where I practiced while working at CERN depends from the Association Culturelle Suisse d’Aïkidō.
• I sometime trained with my brother at Aïkidō-Ōsaka Genève, which follows the Aiki-Ōsaka style, again in the line of Hirokazu Kobayashi.
• When I’m in Mountain View for work, I train at Aikidō-West , which depends of Aikikai Foundation
• I train most of the time at Aikikai-Zürich, which is part of the Fédération Suisse d’Aikidō, which is part of the Fédération Européenne d’Aïkidō, the organisation of Nobuyoshi Tamura.

I won’t pretend I have fully understood the maze of federation and affiliations (this
page details the various aikidō federations that exist in Switzerland), my explanations are probably incorrect in many ways… There is a certain irony to such fragmentation when the first character in aikidō (合) basically means to join, to fit…
