Well, my very first aikido teacher came from the Shiseikan, which is located in the Meiji Jingu complex. Tanaka Shigeo and Inaba Minoru are the resident shihans and their association with Kisshomaru Ueshiba goes back a long way. Tanaka Sensei goes right back to the Founder and Inaba Shihan trained with the late Seigo Yamaguchi. You can also practice Kashima Shinryu there.
I also trained with Shiseikan. Meiji Jingu is worth checking out. There are people of long experience - with whom you would train - and the place itself, well, you will have to look hard to find a better looking dojo.
