The Tsugaru Strait in Japan is one of the most dangerous straits in the world. The weather there is unpredictable and often deadly. A typhoon near the strait killed 1,430 people in 1954. Yet people wanted a way to cross the strait without harm. So, the Japanese government built the Seikan Tunnel. It runs 800 feet (243 meters) below the sea. Two stations in the tunnel serve as emergency stops. The Seikan Tunnel was finished in 1988. It is the world's longest railroad tunnel.

Explanation:

I mean I like japan and i wanna go there some day. but wow :o

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
