As Eisaku got older, he developed a love for surfing and worked to combine his passion for surfing and craftsmanship into surfboard shaping. He used the skills he learned in his father's carpentry shop.
Admiring the work and lifestyle of two legendary shapers, Rusty Preisendorfer and Bob Hurley, Eisaku landed in Huntington Beach, California, 30 years ago.
