Asago City, Hyogo Prefecture, known for “Takeda Castle ruins”, a castle in the sky floating on the sea of cloud, has been gathered attentions for appearing new specialties.

Born is the surprising ultra super underground idle group from Ikuno Silver Mine, which is designated as the Japan Heritage.

And “Dam Hayashi” appeared at “Kurokawa Onsen Hot spring”, which is known to those in the know, a hidden hot spring of Hyogo.

Let me introduce the new specialties that make noises of the place.

A Historical Ruin, Ikuno Silver Mine, One Of The Best Mines

Located about in the center of Hyogo Prefecture is Asago City.

There are a sightseeing spot, “a historical ruin, Ikuno Silver Mine”, as well as “Takeda Castle ruins”, a castle in the sky, floating on the sea of cloud.

Takeda Castle Ruins in the Sky and in Sea of Clouds in Hyogo JapanI'm sure that many of people know Laputa of Ghibli Aniation. Then...

The mine was found 1200 years ago, and it was the one of the best mines in Japan, which was recorded in a book of the Sengoku Era as “there come out silver like do earth and sand”.

It supported Japan as the government managed mine in the Meiji Era, and the Imperial chrysanthemum emblem embossed on the entrance gate tells such history.


Ikuno Silver Mine produced not only silver but also about 70 kinds of ores.

The town was very flourished and it is said that there lived 10 thousand people in the Showa 30s (a decade from 1955).

It is less than half of that time now.

The mine was closed in 1973.

Now, there remain Ikuno Silver Mine, a historical ruin, revived as a sightseeing site, and historical townscape, such as Western-style buildings and former mine government office that were built in early Showa.

There are surprises inside of the mine track one after another.

There remains the trace of excavation by hands of the Edo Period as it was, and also you can see the trace of massive excavation used explosives by under supervision of foreign engineers after the Meiji Era.

The total length of the mine track is more than 350 kilometer and it was excavated till the depth of 880 meter.

Although it is such massive scale, it is said that there was no mining worker who died in collapse of rocks during excavation.

You may understand that rocks of the mine are very firm and solid.

Underground Idol Born In The Underground “GINZAN BOYZ(silver mine boys)” In Iwami Ginzan Silver Mine

Mannequins explain the exhibition inside of the mine track at Ikuno Silver Mine.

Though it is good to show simply the inside of mine track like in Iwami Silver Mine, also popular is the landscape of work that can be understood at a glance, so even kids will not get bored.

The face look is not similar to the Japanese as these are mannequins, so these are completely incompatible to the place.

These handsome mine workers made a debut as idols in summer of 2017.

They are the genuine underground idols “GINZAN BOYZ (silver mine boys).

The debut song introduced in YouTube “Gingira Ginzan Paradise -GGGZPDS-” recorded far more than 70 thousand plays as in the end of November, 2017.

Once Japanese tourist hear the music, you will sing it unconsciously, and the pop melody will not leave from their thought.

Currently, there is no English language version.

As a part of the lyrics is subject to censorship for some reasons, it is interesting lyrics only in Ikuno Silver Mine.

They have also introduced French version in November 2017.

You can watch videos and introduction of members of GINZAN BOYZ on the official website of Ikuno Silver Mine.

For all the boys who might think in disappointment that “though you say an idol, they are boys’ group, aren’t they?”!

There also are mannequins of girls.  Please pay your attention also to the girls, who look so weak with white and smooth skin that you cannot think that they are working inside of the mine track.
