There is not much English language information on this koryu style of martial art. We do know that there are still schools in Japan and some in the United States. We also know that some of the sword technqiues were passed along as part of Keishi Ryu Iaijutsu.

Ueno Takashi Sensei is probably the most noted of the modern teachers of Asayama Ichiden Ryu. Prominent students of his included Sato Kinbei, and Fujita Seiko (aka the last Koga Ninja). It is believed that Shogo Kuniba, founder of Kuniba Ryu Goshindo, learned Asayama Ichiden Ryu Taijutsu from either Fujita Seikoor Ueno Takashi. Kuniba's Goshindo was originally named Goshin Budo Jujutsu and apparently contained the full syllabus of the Shoden techniques.

Asayama Ichiden Ryu and Daito Ryu Aikijujutsu

There are many common techniques between Daito ryu Aikijujutsu and Asayama Ichiden ryu Taijutsu, both of which are said to be the official ryu of Aizu-han. Takeda Sokaku, who is believed to be the founder of modern day Daito ryu Aikijujutsu, was a very close relative of the Kurokochi family, and was in charge of teaching Aizu-han bujutsu and Shin Muso Hayashizaki ryu Iaijutsu (Muraku ryu). It seems he became the adopted son of Kurokochi-den Goro, who was renowed as a master of Aizu budo. Takeda was well educated by Kurokochi-den Goro and learned the martial arts of the Kurokochi family. The Tanaka family, who were the chief retainers of Aizu-han, and the Kurokochi family (who served the lord with Hayashizaki ryu Iai) were families that passed on the lineage of Hayashizaki ryu Iaijutsu (founded by Hayashizaki Jinsuke). Therefore, it is not surprising that Asayama Ichiden ryu was handed down to Takeda Sokaku. It is safe to assume that in the Kurokochi family Takeda Sokaku also learned Asayama Ichiden ryu Taijutsu, Bojutsu, and Tanbojutsu (short stick technique). These techniques are stil in the Daito ryu Aikijujutsu syllabus. This is the reason that the same kata are contained in both lineages.
