Fuji Steel Kamaishi Works opens
After the war, in 1950, Nippon Steel was dissolved as part of the zaibatsu dissolution (a total of 15 zaibatsu, including the four major zaibatsu (Mitsui, Mitsubishi, Sumitomo, and Yasuda), under orders from GHQ. Afterwards, several successor companies were established, one of which was the Fuji Steel Kamaishi Works
Fuji Steel's Kamaishi Works is a blast furnace manufacturer that took over the steel division of Nippon Steel, and is the second largest producer of crude steel (steel that has been refined in converters and electric furnaces before being processed by rolling or forging) in Japan, making it a major blast furnace manufacturer alongside Yawata Steel, another successor to Nippon Steel
Merger with Yawata Steel Co., Ltd. to form Nippon Steel Corporation
Subsequently, in 1970, Fuji Steel's Kamaishi Works merged with Yawata Steel Co., Ltd. to become Nippon Steel Corporation, with the aim of responding to the increasing size of facilities, eliminating overlapping investments amid sluggish demand, strengthening technological capabilities, and strengthening international competitiveness amid capital liberalization and large-scale restructuring in the steel industry
Nippon Steel Corporation surpassed US Steel to become the world's top annual crude steel producer, becoming the first Japanese company to achieve sales of 1 trillion yen
From a city of iron and fish to a city of iron, fish and rugby!

Kamaishi City is also famous as a rugby town, and the Nippon Steel Kamaishi Seawaves have a long history, originating from the corporate team of the Fuji Steel Kamaishi Works, which was founded in 1959.
Although the team first participated in the National Amateur Tournament in 1962, they struggled, losing to the Osaka Prefectural Police in the first round. However, after merging with Yawata Steel Co., Ltd. in 1970, they began to grow significantly
Due to a company merger, the name was changed to "Nippon Steel Kamaishi Rugby Club."
In 1970, when the company changed its name to Nippon Steel, the team name was also "Nippon Steel Kamaishi Rugby Club ." In the same year, the team won the National Amateur Tournament for the first time, and this marked the beginning of Kamaishi Rugby's winning streak.
From 1978 to 1984, they achieved the remarkable feat of winning the National Amateur Tournament and Japan Championship seven times in a row, "Ironmen of the North" , and becoming a team that defined an era in Japanese rugby history. They won a total of 26 national titles (Japan Championship: 8 times, National Amateur Tournament: 9 times, National Sports Festival: 9 times). They also won the YC&AC JAPAN SEVENS in the seven-a-side rugby tournament, making Kamaishi widely known as a "rugby town."
The team's last appearance in the tournament was in the 1992 National Amateur Tournament, and then in 2001, as part of a review of Nippon Steel's sports business operations, the Nippon Steel Kamaishi Rugby Club came to an end
However, in the same year, the team was reborn as a private club team closely connected to its home city of Kamaishi, and restarted under "Kamaishi Seawaves RFC."
from "Kamaishi Seawaves RFC" "Nippon Steel Kamaishi Seawaves," incorporating the name of its main sponsor, Nippon Steel (which changed its name in 2019), and continues to make great strides.
For these reasons, Kamaishi is known as a rugby town, and is equipped with a full-scale rugby stadium, which is rare in the Tohoku region
Kamaishi Unosumai Memorial Stadium, completed in 2018

The Kamaishi Unosumai Memorial Stadium was completed as one of the main measures supporting the reconstruction of the area, on the site of the former Kamaishi Municipal Unosumai Elementary School and Kamaishi Municipal Kamaishi Higashi Junior High School, whose buildings were completely destroyed and flooded in the tsunami caused by the Great East Japan Earthquake, which was caused by the Tohoku Pacific Coast Earthquake on March 11, 2011
It is a stadium dedicated to ball games located in Kamaishi Unosumai Sports Park in Kamaishi City, Iwate Prefecture, and in 2019 it was one of the venues for the Rugby World Cup, hosting the match between Fiji and Uruguay

summary
Kamaishi City in Iwate Prefecture has flourished as an iron town since the Edo period, and was also an important place from the perspectives of shipping and fishing
It is a city as strong as steel that has risen again and again despite suffering severe damage during World War II
This strength has also been demonstrated in the sport of rugby
Kamaishi City is expected to continue to develop in the future, so I highly recommend visiting it at least once
