The Tenri University International Cooperation Project responded to the 2001 earthquake near Jamnagar, India by sending a group of 15 students and other personnel, including Akio Inoue as the project leader. They stayed for two weeks and constructed two bongas (earthbag dome shelters with thatched roofs) near the village of Moda. They also planted 1000 young bamboos to use as roofing material to connect three earthbag domes for an elementary school in the Bolachadi village of the north-eastern area of Jamangar. These three domes were completed by subsequent groups of students over the next three years and were used for a library at the elementary school, which had suffered much damage from the earthquakes. These structures measured about 3 meters in diameter and 4 meters high.

Sometimes they hired Indian workers, but also interested pupils and neighbors cooperated in the building when they covered the completed domes with cement stucco.

In addition to the disaster relief work mentioned above, Professor Inoue and his students have constructed 23 earthbag domes of various sizes in Japan, mostly on the campus of Tenri University as a Model Ecological Design Center.

In Entebe, Uganda, the Tenrikyo Mission Center assisted Professor Inoue and some of his students with building some small earthbag domes, where they used the abundant soil taken from anthills to fill the bags. These domes are being considered for use as refugee shelters in the region, because they provide good protection from bullets, fire, wind, and rain…much better than the conventional thatched shelters or tents. Also, plans are under way for the construction of a Grameen Pig Bank and a church using the earthbag technique.
