Outer Metropolitan Area Drainage Channel “G-Cans” tour (6hours)

The Outer Metropolitan Area Drainage Channel, well known as “Underground Temple” or “G-Cans,” is one of the world’s largest drainage channels.
This tour will visit the Underground Temple and Vertical Hole.
It is located in Saitama Prefecture, next to Tokyo Prefecture. So, we will use trains and other public transportation to get there. It takes about 1 hour and a half for one way. After the Outer Metropolitan Area Drainage Channel, we will come back to Tokyo.
