On my cycling trip around Lake Biwa I found Takashima held a number of surprising finds. Just outside JR Omi-Takashima station there is a large statue of Gulliver. Why Gulliver? I looked for a reason or explanation.
I studied the station map but it didn't offer any clues at all. Later I found out that there is a recreation area called Gulliver Park nearby.
guided tour of the houses (but no English.)
A sign said "Prirate School Ruins." Do they mean pirates? On lake Biwa?! Perhaps not... following the tantalizing sign I only found what looked like another country shrine. No more English.
A little later at Shin-Asahi I found Dutch style windmills, and a pond with swans and geese. There were ticket booths but they were broken. I put in money and it fell straight through, so I went in for free. Geese waited expectantly by a vending machine dispensing food.. An extraordinary children's playground nearby held a castle, a pirate ship, and giant geese and mushrooms.
Then, on apparently empty land beside the lake, a very European looking brass mermaid statue.
Like I said, random!
