The eccentric tycoon is back in the islands.

This week, he was tackling the rubble strewn grounds on what he envisions as home to a future art museum.

His collection of marble statues and lions and temples is growing, and growing, and growing.

The development of Genshiro Kawamoto's gardens have been mostly on the oceanfront properties.  But in recent months, Kawamoto has taken to beautifying the mauka side of Kahala Avenue.

The billionaire's flowers and nymphs are Kawamoto's answer to chronic complaints by neighbors that some of his derelict properties are ruining the neighborhood.  

Kahala resident Richard Turbin calls the trashy statures and rubble an eyesore.

But he points to other abandoned homes that he said are a growing hazard.

"Some of the property is used by squatters, by homeless people that is creating a dangerous situation and they yell at night. They are public nuisances and Kawamoto doesn’t police those properties," 

Under a public nuisance bill advanced today by state lawmakers, private homeowners could take action if three complaints go unresolved for three years.

But the House Water and Land committee cut the time to a year and a half, as a message to state and city regulators to act sooner.
