Dear Jorgen,
Yes Takeda Shihan has from the beginning of his Aikido experience been connected through Aikikai Honbu. He was a long time student of Yamaguchi Seigo Shihan ( deceased ) a Honbu Instructor. Takeda Shihan is a director on the Board for Aikikai Honbu. and is very close to the Doshu on Aikido activities. Also each year During May the A.K.I. celebrate with one whole day of Social activity with Doshu UESHIBA. An Enbukai followed by a big dinner with introductions and speeches Takeda shihan Shonan Aikido Renmei organisation Japan has expanded outside Japan and taken on the title of Aikido Kenkyukai International ( A.K.I ) which when translated means Aikido Research Group.
When you have the opportunity to experience his liberating and deeply connected Aiki experience then you will discover new opportinity in your own practise and direction. I believe so.
All the best to you Jorgen
