If you ever get a chance to cruise out to Miyazaki you should look up Shinya KD Kodaira. Shinya owns a small back yard landscaping companies that specializes in Concrete work of all kinds.
I have known Shinya since pre-covid Times and have watched his personal DIY grow from 3 quarter pipes to bowls, hips and so much more.
Anyway, if your ever out towards Miyazaki, you might want to reach out. Hopefully link up, maybe hit a surf and then shred the DIY.
