Mr. Kashiwadate of AIJ Tohoku chapter visited Kamaishi City, Iwate Prefecture, on March 12 and 13, 2011.
The Disaster Committee, Tohoku Chapter, provided the photos of the area to the AIJ Disaster Committee.
Kamaishi City is located in the south east of Iwate Prefecture, approximately 100 km to the south east of
Morioka City. The city is famous for fishery base (one of the three largest bases for ocean fishery in the
world). After New Japan Steel closed blast furnaces, the population of the city is decreasing. The city
faces a Rias coast, highly susceptible to tsunami attacks.
The following photos show the influence of tsunami wave attack.
(1) U-no-sumai-cho, Kamaishi City
The town faces Ohtsuchi Bay. The photos are from the west part of U-no-sumai-machi (residence of coal
geese). The town was washed away by tsunamis; only reinforced concrete (RC) and concrete block
masonry buildings were left standing. .

This report describes the tsunami damage of Yamamoto-machi, located at the southern end of Miyagi
Prefecture. Two residential houses owned by faculty members of Tokyo Institute of Technology were
washed away and destroyed by tsunami attacks. They and their families are living in shelters. The
tsunami wave height reached as high as 3 to 4 m in Yamamoto-machi. Damage of houses was very light
in the areas where tsunami waves did not reach.

Mr. Koichi Ishioka, Ishinomaki Technical High School
This report includes photos taken by Mr. Ishioka of Ishinomaki Technical High School. The photos depict
the damage caused by tsunamis. He was confined in his school from immediately after the earthquake on
March 11 to noon on March 12. Mr. Ishioka sent the following message;
Two weeks have passed since the tsunami earthquake. During this period, I was involved in
contacting all students and staff of the school. The safety of all students and staff was confirmed the
day before yesterday. This is a miracle. The last student found safe was our student in Department of
Architecture, living in Ayukawa district. On the other hand, many losses of students were reported in
our neighboring schools. Let me send photos taken during my visit to various places to check the
safety of my acquaintance, in Kadowaki, Minami-hama, Minato-machi areas and factory of a paper
manufacturing company, where tsunami damage was worst.

This report describes tsunami damage of Arahama District, eastern part of Sendai City, approximately
30-minute drive from JR Sendai Station. Route map is shown at the end of this report (Fig. 1). The
damage investigation was carried out along National Route 137.
The observed damage may be summarized as follows:
(1) The outflow items were seen to increase beyond the Sendai Tobu Highway, but out flown houses
could not be seen in this area (Photos 1 to 3).
(2) Toward Arahama District, more damage was seen to houses and buildings (Photo 9).
(3) Near the Sendai Municipal Arahama Elementary School, most timber houses were flown out and
collapsed by tsunami attacks (Photos 10 and 11).
(4) Damage of the Sendai Municipal Arahama Elementary School buildings is shown in Photos 12 and 13.
The first two stories of the four-story reinforced concrete buildings were submerged under tsunamis and
the first story of the building was filled with overflow materials. The buildings were retrofitted before the
earthquake and structural damage was not observed.
(5) No timber houses remained standing between the Arahama Elementary School and the coast. Only
steel construction and reinforced concrete buildings were standing (Photos 14 to 18).
(6) Photo 19 shows a breakwater embankment at the coast. No damage was observed to the
embankment, but the tsunami wave crossed over the embankment.
(7) Photos 20 and 21 show the hand rails on the embankment; one in the direction of tsunami flow
suffered no damage, but the rail normal to the flow was damaged totally from its base.
