Nippon Light Metal Holdings Ending Its Electrolytic Aluminum Smelting Businessat Subsidiary
Nippon Light Metal Holdings Company Ltd. announces that Nippon Light Metal Co., Ltd.
(headquarters: Shinagawa-ku, Tokyo; President: Ichiro Okamoto), its wholly owned
subsidiary, will discontinue its electrolytic aluminum smelting business at its Kambara
Complex in Shimizu-ku, Shizuoka City, on March 31, 2014.
The ending of its electrolytic aluminum smelting business will have only a minor impact
on the consolidated business results for the NLM Group in the same period (endingMarch 2014) as the closing of the smelting operations.

Nippon Light Metal Co., Ltd.
Discontinuation of Electrolytic Aluminum Smelting BusinessNippon Light Metal Co., Ltd. (headquarters: Shinagawa-ku, Tokyo; President: IchiroOkamoto) announces that it will discontinue its electrolytic aluminum smelting businessat its Kambara Complex in Shimizu-ku, Shizuoka City, on March 31, 2014 as follows.
1. Ending of Nippon Light Metal’s electrolytic aluminum smelting
It is said that the aluminum smelting industry in Japan had virtually collapsed due to thetwo oil shocks in the 1970s, but Nippon Light Metal Co., Ltd. (hereinafter, NLM)
continued its electrolytic aluminum smelting business, though on a small scale. With thealuminum ingots produced at NLM’s Kambara plant having an average purity of 99.95%,
higher purity than that for other ingots (99.7% purity) sold on general markets, theseingots are mainly being used as the base material for NLM’s high-purity products in theelectrical and electronics field. Particularly in this field, this purity is a great advantagethat allows product development from the materials stage, and the quality of NLM’s
high-purity products has earned the trust of many customers. However, NLM’selectrolytic furnaces and related equipment have aged significantly, and a very substantial
investment would be required to renew these facilities in order to continue the aluminum
smelting business in the future.
As a result of in-depth consideration based on the above-mentioned situation, NLM
decided to discontinue its electrolytic aluminum smelting business.
NLM has received the approval of its customers for the decision to use a new material for
NLM’s high-grade aluminum (high-purity ingots) with imported ingots as their basis, andwe will continue to provide our products as before even after the ending of NLM’selectrolytic aluminum smelting business.

Reference — Overview of NLM’s Aluminum Smelting BusinessNippon Light Metal Co., Ltd. was established in March 1939 through a tie-up between
Furukawa Electric Co., Ltd. and Tokyo Dento (currently TEPCO), with the plan of
making it one of the world’s leading aluminum companies at the time, annually
producing 100,000 tons of alumina and 50,000 tons of aluminum. Construction of analuminum smelting plant in Kambara in Shizuoka Prefecture and of an alumina plant inShimizu, near Kambara, was commenced, and NLM’s aluminum smelting operations got
underway from October 1940. Initial annual production capacity was 9,000 tons (allproduction figures hereinafter are annual amounts), but it expanded to 36,000 tons in1943. Coinciding with this, construction of a smelting plant (Niigata Plant) with aproduction capacity of 18,000 tons was launched in Niigata City, and operations began atthat plant from January 1941.
When the Second World War ended in August 1945, NLM’s main facilities had escaped
damage from the war, but because of the depleted supplies of bauxite and other raw
materials, production at NLM’s plants had effectively stopped. With the changes in theinternational situation brought on by the US-USSR Cold War in the background, NLM
went through a very trying period, producing as its only marketable commodities lowgrade aluminum from scrap metal, salt produced through electrodialysis, and others, until
imports of bauxite were resumed in April 1948, and NLM was able to begin shipping
new ingots from June of the same year. After that, a special procurement demand wasgenerated by the Korean War, which broke out in June 1950, while in Japan, demand foraluminum, particularly for aluminum sheets and extrusions and electric wire, grewsteadily. From 1955 to the mid 1960s, demand for aluminum rapidly increased, fueled by
Japan’s economic growth, and Japan’s aluminum production skyrocketed ten-fold from50,000 tons in 1955 to 500,000 tons in 1967, with estimates that it would reach one
million tons in the near future. All of the aluminum smelting companies embarked on
new investment in plants and equipment. In 1958, NLM resumed and expanded
production at the idled Niigata Plant, and increased production capacity at its Shimizu

Plant and the Kambara Plant. The company also decided to construct a smelting plant at a
new site in Tomakomai, and construction on it began in April 1968.
Although there were subsequent ebbs and flows in production due to business cycles,
demand generally increased, and Japanese smelting companies continued to boost theircapacity. By May 1967, 26 years after first starting operations, the Kambara plant had
become one of the world’s leading aluminum smelting plants, with a production capacityof 109,000 tons. Its highest production capacity was 113,000 tons (1974), and NLM’scombined production capacity at its Kambara, Niigata and Tomakomai plants reached
370,000 tons at its peak aluminum production period (1975). At that time, Japan overall
had achieved its highest smelting capacity of 1.64 million tons (1978; in that year, bycompany, Sumitomo Chemical Co., Ltd. had the highest production capacity at 410,000tons).
However, Japan depended on thermal power generation for around 70% of its energy
needs, and Japan’s smelting industry was dealt a fatal blow by the rapidly rising
electricity costs sparked by the oil shocks of 1973 and 1979. The international
competitiveness of Japan’s smelting industry vanished, and the government deemed thatthe smelting industry was a structurally depressed industry. Heeding the advice from theIndustrial Structure Council, a government-related advisory body, smelting companies
slashed their production capacities. As a result, the smelting industry, as a distinct
industry, disappeared at an unprecedented speed of just over 50 years from Japan’s
industrial landscape. In 1980, NLM discontinued operations at its Niigata Plant, and in1985 closed its Tomakomai Electrolytic Plant. Since 1987, the Kambara Plant, which isrun by hydroelectric power, has been NLM’s sole remaining smelting plant, curtailing its
production capacity at that time to 35,000 tons.
The Kambara Plant has continued its operations up to today, although its production
capacity fell to 20,000 tons in 1995 and to 11,000 tons in 1999. Since it started its
operations in 1940 up to the present, the Kambara Plant has produced a total 2.82 million
tons of aluminum ingots. Combining the total production amounts of the Niigata Plant

and the Tomakomai Plant together with that of the Kambara Plant, NLM has produced atotal of 5.21 million tons of aluminum ingots, equivalent to 30% of the entire aluminum
ingot production in Japan of 17.58 million tons.
