In all the serious literature that I have seen, the distinction between the Tachi and the katana is about how they were worn/slung and not about hilt length. Tachi edge down, katana edge up. And I have never seen a tachi or katana with a one hand hilt nor any suggestion to this effect.

From Wikipedia:

The tachi (??) is a Japanese sword, often said to be more curved and slightly longer than the katana. However Gilbertson, Oscar Ratti, and Adele Westbrook state that a sword is called a tachi when hung from the obi with the edge down, and the same sword becomes a katana when hung edge up thrust through the girdle. The Tachi style was eventually discarded in favor of the Katana. The daito (long swords) that pre-date the katana average about 78cm in blade length, next to the katana average of around 70cm. As opposed to the traditional manner of wearing the katana, the tachi was worn hung from the belt with the cutting-edge down, and usually used by cavalry. Deviations from the average length of tachi have the prefixes ko- for "short" and o- for "great" attached. For instance, tachi that were shoto and closer in size to a wakizashi were called "kodachi". The longest tachi (considered a 15th century odachi) in existence is more than 3.7 meters in total length (2.2m blade) but believed to be ceremonial. During the year 1600, many old tachi were cut down into Katana. The majority of surviving tachi blades now are o-suriage, so it is rare to see an original signed ubu tachi.

Form The Connoisseurs Book Of Japanese Swords by Kokan Nagayama:

Tachi: This is a curved sword with a blade longer than 60cm. It was worn suspended from the belt with the blade edge facing the ground. Later some blades originally produced as tachi were converted into katana by shortening the tang (or the portion of the blade that extends below the hamachi) This process inevitably caused any signature to be lost. Blades longer than 90cm are known as o-dachi (long tachi) while those 60cm or shorter are known as ko-dachi (short tachi)......Katana: Have blades longer than 60cm and are worn through the belt with the cutting edge facing upwards

I could give a number of other citations from respected authorities, but for lack of space will refrain from doing so. However, I'll add that the only Japanese native long-sword that I am aware of that was used with one hand (according to some sources) was the uchigatana, which appeared late in the Muromachi period. It complemented the Tachi when fighting afoot and is considered the precursor of the katana, as was worn edge up.

That the double handed grip was a handicap was recognized by the legendary Musashi in 1645 when he wrote"...It is encumbering to hold a sword with both hands when you are on horseback..."(Book of Five Rings). Note that Musashi was trying to correct the then prevailing practices, perhaps being influenced by Europeans

"Kyugunto" mounting (the western-style you refer to) had ancestral blade inside. Is more a matter of mounting rather then blade shape.
It's easy to find asking any average collector out there or taking a look at
Fuller and Gregory's "Military swords of Japan 1868-1945" ISBN 0 85368 796 X ..

It will do us well to remember that the Tokugawas curtailed the maximum length of blades so as to prevent warfare and most long tachis were cut down to fit in with the peace time requirements. By the Meiji restoration most katanas were of the order of 70cm, considered to be the standard length. So if we examine the bulk of those strange swords, with a knuckle-bow attached to their longish hilts, we will find a rather short blade - Totally unsuited for mounted use.

Additionally, the tang of the Japanese blade follows the curvature of the blade and makes it impossible to fit a downward drooping hilt, as was generally considered desirable in a cavalry weapon by that era. The downward drooping hilt is essential when using the point as when the arm is extended the curved blade's point is aligned with the axis of the arm.

Rough terrain and lack of space for horsebreeding.
These are the reasons they didn't apply vast cavalry charges as we're used to think about. This is not lack of understanding, this is lack of needs...

To my mind lack of needs equates with lack of application, which equates with lack of experience and thus of understanding.

agree we're out of topic and warmly suggest you to open another thread onthe matter if you want to discuss further this very interesting matter.

Happy to oblige by PM, unless other forumites want to join in, in which case we will open a fresh thread.

Cheers
