HONOKAA, BIG ISLAND (HawaiiNewsNow) - On Tuesday, Wayne Kawachi started a 100-mile trek from Honokaa to Naalehu.
If the journey on foot wasn't long enough, there's another twist — he's wearing slippahs and he plans to wrap up his hike by Friday.
Kawachi is taking on the challenge to raise $250,000 for senior housing on the Big Island.
He's the president of O Kau Kakou, a nonprofit that seeks to sponsor educational, cultural and economic development projects and activities.
And he's got a big goal: With the money that's raised he wants to fund 25 to 30 affordable units for seniors in the heart of Naalehu.
"I'm excited about this project. I'm training. It's going to be done, and I'll need your kokua!" he said, in a YouTube video before he started the walk.
The nonprofit is no stranger to major fundraising efforts.
In the past, its raised $52,000 for the Naalehu Bay Clinic and $80,000 for a bus to take kupuna and keiki on outings.
