本気で途方に暮れました。
もともとここを見るために帰りの飛行機を遅くしてたので、これ以外全くノープランでしたとさ。
なんで定休日調べてなかったのかなー(笑)
このマスコットは、入り口で「こっちこいよ」的にトンネルの方を指さしてました、ちなみに2コマ目の石炭掘削用のカッターはトランスフォーマーみたいでかっこよかったです(笑)

I was really at a loss here. I delayed my flight back home in the first place in order for me to see this spot, so I had no other plans but this. I wonder why I didn't check their scheduled holidays. (Laugh)

The mascot here was at the entrance, pointing towards the tunnel like it was saying, "Come this way." By the way, the coal excavation cutter on the second panel looked really cool, like Transformer. (Laugh)
