The Nobeyama Radio Observatory in few words

The Nobeyama Radio Observatory (NRO) is a division of the National Astronomical Observatory of Japan (NAOJ) and consists of three radio instruments located in Nobeyama, a village in the Japan Alps at an elevation of 1350m.
- The 45m Radio Telescope: A 45m single-dish radio telescope that operates in millimeter wavelengths.
- The Nobeyama Millimetre Array (NMA): An millimeter interferometer consisting of six 10m diameter telescopes.
- The Nobeyama Radioheliograph: An array of eighty-four antennas dedicated for solar observations.

The 45 m antenna constitutes the largest radiotelescope in the World in millimeter wave-lengths, and is dedicated to study newly born stars and galaxies as well as the interstellar medium.

Welcomed by Prof. Nario Kuro, the Nobeyama Director, at his office. Some gifts were presented in the form of astronomical posters produced by Sirius some of which were translated from Japanese.

Getting explanations from Prof. Kiyoto SHIBASAKI on the history of the facility and the working of radioastronomy.

Night pictures and time-lapse is an art which implies some hardship

Of course once things set up, some rest can be taken...

... and here is one shot after having superimposed the constellation lines.

On our Way to the Sacred Mountain

Mt. Fuji looming away.

At the mineralogy Museum on our way to Mount Fuji

Next to it was a Shintoist temple mixing blithely imposing geological gems and fantagasmoric animals. Inside the altar was a donation box for the faithful.

Shopping for gems and souvenirs

Mount Fuji ahead of us

A string of temples lies at the base of the sacred mountain which peaks at 3776m above sea level.
At the Megastar Company: Ohira Tech
(Ohira Tech was one of our main sponsors for our stay in Japan )

With Dr.Alexander Adli as our guide. Peeping at an intricate chemical process room where the star plates are produced using state of the art technology. The process is at the heart of Megastar success and it involves advanced laser tools and photochemical technology.

The main offices. We also visited the conception and testing rooms but for obvious reasons, we were not allowed to take pictures there.

At a planetarium theater equipped with a Megastar projector. Here the main medium sized projector

Getting a Dose of Japanese Culture
Strolling in Town...

Attraction parks and coaster roller. Including in our visit was the Tokyo Sky Tree, the largest self supporting tower in the World with a a height of 634 m.
