• Coordinates: 34°36'52''N, 129°27'14''E.

• This structure is one of only 8 OMEGA transmitters in the world, and one of the tallest constructions of Japan.

• The mast was a steel tubular mast (perhaps the tallest steel tubular mast ever built) insulated against ground and guyed in 6 levels. Additionally guy-like wires from its top which served for electrical enlengthening run from the pinnacle to the ground.

• After the shut-down of OMEGA navigation system, it was dismantled in 1998 piecewise http://www.yokogawa-kouji.co.jp/bridge/topics/topics02.html.

• The basement of the mast remained (without the insulator) remained on the site as monument. The helix building nearby was demolished and a playground was built there http://daisukenigou.blogzine.jp/daisukediary/2006/09/post_6e0d.html
