Because of that, we know that this one was built in 1978. The tuners here, confirms that, since they were only used with the Gotoh mark, from 1977- early 78, Mugen Mark 1, is entry level Daion. They were the cheapest Daions you could find. They are still amazing instruments, but nothing compared to fx a Mark 5, 82 Jumbo, or even a 78 Heritage. - thank you for this Michael!. more info from online: Daion was founded in 1962 by Yasuyuki Teradaira. The story of Daion and Yamaki guitars is entwined with the histories of a number of other Japanese companies.
In the late 1940s, brothers Yasuyuki and Kazuyuki Teradaira started working for Tatsuno Mokko, an instrument-building firm that later split into two different companies, one of which was called Hayashi Gakki.
In 1954 Hayashi Gakki was bought out by Zenon, a large music distributor.
In 1962 Yasuyuki left Zenon to start an instrument distributor he called Daion, located in Osaka and Daion is the Wholesaler of the Musical Instruments, and Daion distributed Yamaki guitars exclusively throughout Japan. Daion means “big sound” in Japanese.

In 1967 Kazuyuki left Zenon to produce classical guitars under the name Yamaki located in Suwa City, Nagano Pref., an auspicious Japanese word meaning “happy trees on the mountain.
By the early 1970s, Kazuyuki expanded the Yamaki line to include a large number of steel-string guitars, many of which were based on C.F. Martin and Co.’s designs and were distributed exclusively through Daion. Along with Yamaki guitars, Daion sold instruments from Shinano, Mitsuru Tamura, Chaki, and Hamox, some of which were built by Yamaki at various times, and Harptone guitars, which they imported from the US.

 it was a distribution company until 1977. Daion distributed and exported instruments made mainly by Yamaki but not exclusively. Yamaki was founded by Yasuyki's brother, Kazuyuki Teradaira. 

In 1974 Yamaha made a name claim, that Yamaki was too close to Yamaha, and threatened to sue. Because of that, Yamaki had a couple of different names from 1974-1977 when it came to exported instruments. Kirzan was one of the main ones. 

In 1977 they changed to Daion, when Mr. Hiro-san (Hirotsugu Teradaira, son of Kazuyuki/Daion founder, and nephew to Yasuyki/Yamaki founder). It was Mr. Hiro-sans suggestion to change the brandname to Daion. So from 1977-1984 all Yamaki instruments produced for export, was branded Daion. It was only for the Japanese market they still produced instruments under the Yamaki brand.
