Expedition Amana is a project to investigate the possibility of a new ancient maritime route by hypothesizing that before Polynesians arrived in the Hawaiian Islands, Native Americans may have traveled from California in reed boats, the oldest boats made of bundles of grass.


This project aims not only to unravel the mysteries of ancient navigation and seaborne migration patterns, but also to gain a new understanding of the environmental changes caused by ecological migration carried by reed boats from an environmental and biological perspective.


In addition, the project will utilize the latest technology live-streaming to share ancient voyages with the world and promote a deeper understanding of education, science, and culture.

This project symbolizes ancient wisdom rooted in harmony with nature, and will inform the world about how to interact with the natural environment in a sustainable manner.

Project Overview

 2023, April

Create half size of boat and do test voyage in San Francisco bay.

Test Reed boat will be half size of "Amana" (Around 30 feet).

We would like to confirm following things through the test boat.

1.  Mast position

2.  The size and shape of sail

3.  The size and shape of rudder

4.  Sailing maneuverability this new design

June 2025,

Start on a voyage from San Francisco to Hawaii islands.

Based on results of test boat, we will make new " Amana" (around 60 feet).

Recreating the life of an ancient voyage on a reed boat with 7 crews, we will ride the winds and currents to sail to Hawaii, 2,500 nautical miles (4,000 km) away, for about 50 days.

December 25, 2019 thanks to your help, it was approved.


Reed Boat made more than 7,000 years ago.

Reed Boat had been used for many purposes such as transportation and delivery.

It was used on lake, river, and sea and appeared in ancient civilization like Mesopotamian, Egyptian, Europe, Asia and all over the American continental.
