Report Highlights:

In 2012, Japan’s potato production increased by four percent to 2.43 million metric tons. Given this increased availability of domestic potatoes, imports of fresh potatoes declined slightly. However, imports of frozen potato products, particularly French fries, continued to be robust. A potential contraction in Japanese domestic potato production, expected to occur over the next decade, could present greater opportunities for imports, particularly U.S. potatoes, as they are highly valued in quality and price by Japanese users and consumers. Aggressive and strategic marketing activities by the U.S. potato industry have been instrumental in developing new demand in growth sectors.

Market Overview

Between the 1970’s and 1990’s, per capita consumption of potatoes in Japan increased with the expansion of fast food restaurants serving French fries, reaching a peak during the late 1990’s. Following the economic slowdown, starting in the late 1990’s, per capita annual consumption has been hovering around 15 kilograms.

Japan’s aggregate potato demand peaked in the mid 1980’s and over the last decade has fluctuated between 3.0 and 3.7 million metric tons. During this time, domestic production has been steadily declining, with imports picking up the slack.

Fresh Potatoes


Hokkaido, Japan’s northernmost island, is the major potato producing region, accounting for nearly 80 percent of the nation’s total output. Hokkaido’s cool temperatures and large-scale agricultural land provide suitable conditions for potato production. Potatoes in the Hokkaido region are planted in late spring, after the ground has thawed, and are harvested in September and October. Much of Hokkaido's potato production is kept in stocks and is available to the market through the following spring.

Honshu, the main island of Japan, and Kyushu, its southernmost island, also produce potatoes. Potatoes in Honshu and Kyushu are largely planted in the spring and harvested from April through August. These potatoes are mainly sold fresh as soon as they are harvested.

In 2012, production of fresh potatoes increased by nearly four percent from the previous year to 2.43 million metric tons from a total planted area of 78,100 hectares. With fair weather conditions, average yield improved slightly from 30.0 kilograms (KG) per hectare (Ha) to 31.1 KG per Ha. The Hokkaido region produced 1.92 million metric tons, up approximately four percent from the previous season.

According to trade sources, due to a slight lack of rain during the growing season in Hokkaido, the size of potatoes is expected to be smaller this season. However, overall production volume in Hokkaido and throughout the country is forecast at same level as last season. Over the next decade, Japan’s potato production is expected to further decline due a number of factors, such as decreasing farm size and aging famers retiring without successors. Given these challenges, Japanese manufacturers of potato products, such as potato chips, remain concerned about the future availability of domestic potatoes for processing.


As reported in the Market Overview section, per capita consumption of potatoes in Japan has remained around 15 kilograms over the last decade.

According to Japan’s Ministry of Agriculture, Forestry, and Fisheries (MAFF), 34 percent of Japanese potatoes are consumed fresh at households and restaurants. The starch industry uses 37 percent, and the food processing sector, including potato chips and frozen potato product manufacturers, utilizes about 21 percent. The remainder is used primarily as seed potatoes.

Trade – Imports

In MY 2012/13, Japan’s imports of fresh potatoes from the United States reached approximately 15,500 metric tons, almost repeating its record level of the previous year. The Japanese government first began allowing imports of U.S. fresh potatoes in 2006, entirely for potato chip manufacturing. Several developments contributed to the robust growth of Japanese imports of U.S. chipping potatoes in MY 2011/12, including a one-month extension to the allowable shipping period (increasing the period from February to July) and the approval of a new processing facility in Kagoshima on the southern island of Kyushu. In addition, during the 2012 shipping season, the United States secured MAFF’s approval of two additional U.S. states (Nevada and Montana) as eligible potato shipping states (see policy section). This approval significantly contributed to the increase in imports of U.S. fresh potatoes in MY 2011/12 (see policy section). With two chipping facilities approved to handle U.S. potatoes (in Hiroshima and Kagoshima) Japanese potato chip manufacturers doubled their imports from the previous year.

However, in terms of policy developments, the 2013 shipping season was a stand-still. No additional states or facilities were added, and the shipping season remained the same (February-July). With an increase in domestic potato production, coupled with the weakened value of the yen, demand for U.S. chipping potatoes did not grow last season. However, the fact that imports remained near the previous year’s level shows the manufacturer’s commitment to purchasing from the United States now that the relationship between U.S. suppliers and Japanese manufacturers has been established, and is expected to strengthen in the coming year.

Trade – Exports

Japan’s exports of fresh potatoes are negligible (seven metric tons in MY 2012/13). As total demand for fresh potatoes in Japan exceeds the domestic production capacity, there appears to be little incentive to expand exports in the near future.


Eligible states: Currently, Japan allows imports of U.S. fresh potatoes strictly for chip manufacturing. Under the protocol established in 2006, 14 U.S. states were eligible to ship potatoes to Japan under certain conditions, including field designation. Originally, eligible U.S. states were: Idaho, Arizona, Wisconsin, Oregon, California, Colorado, Texas, New Mexico, North Dakota, Florida, Michigan, Minnesota, Maine, and Washington. However, when the market opened, only fields from the state of California had been designated to ship fresh chipping potatoes to Japan. In 2010, after extensive bilateral consultations and successful MAFF on-site audits, fields in the state of Washington were designated to be able to ship to Japan. In 2012, MAFF also registered Oregon, Nevada and Montana as eligible to ship to Japan.

Shipping season: Starting in 2012, MAFF extended the shipping season to include the month of February.

Inland transportation: According to the 2006 import protocol, MAFF does not allow inland transportation of U.S. potatoes from the port to the chipping facilities due to phytosanitary concerns. As a result, only port-area chipping facilities are allowed to request MAFF for approval to import and process U.S. potatoes. Unlike the Hiroshima Port, the Kagoshima Port, where the newly- approved facility is located, is a local port that cannot handle large-scale vessels. Consequently, U.S. potatoes need to be loaded onto smaller coastal vessels at the nearest port (Shibushi) approximately 100 kilometers east of Kagoshima. As the smaller vessels are not equipped to keep the cargo refrigerated, the eight to nine hour travel time to Kagoshima can cause premature sprouting and adversely affect the quality of the potatoes. Additionally, Japanese chipping manufacturers find the current process extremely inefficient and costly. Thus, they have requested MAFF to allow inland transportation by truck from the Shibushi port directly to the chipping facility. The Shibushi port has the capacity to handle containerized cargo and is equipped with electricity which would allow the potatoes to remain refrigerated. In addition, the shorter inland travel time would minimize the risk of quality deterioration. MAFF is currently reviewing this request.


During the first few years following the 2006 market opening, Japanese imports of U.S. fresh potatoes were limited to below 1,000 metric tons annually, mainly due to Japanese chip manufacturers’ unfamiliarity with the quality and characteristics of U.S. fresh potatoes. Working closely with Japanese chip processors, U.S. potato exporters have supplied high quality potatoes, providing suitable potato varieties and successfully meeting the needs of the Japanese manufacturers. As a result, the Japanese industry reports that the rate of rejection for imported U.S. potatoes over the last few years was very small. Additionally, during the 2011 and 2012 seasons when Japan’s potato production declined, the strong yen also significantly contributed to the increased imports of U.S. potatoes. However, in 2013, with the weakened value of the yen, as well as the recovery in Japan’s domestic production, demand for U.S. potatoes remained flat.

When Japan started importing U.S. fresh potatoes, it imported only fresh-crop potatoes from California and only during the months of June and July. In order to increase the volume of imports from the United States, Japanese traders looked for additional sources within and beyond the state of California. During the 2011 season, Japan imported stored potatoes (the previous year’s crop) from the state of Washington. Since then, Japanese chip manufacturers have been able to confirm the quality of stored potatoes and verify that other potato varieties can meet their needs. The U.S. Potato industry has been working with the Japanese chip manufacturers through reverse trade missions and other activities to assist them in testing new potato varieties and expanding their U.S. purchases. These efforts led to Japan to begin purchasing stored potatoes from Nevada in 2012.

Frozen Potato Products


Production of frozen potatoes in Japan has been flat in recent years. Production of frozen French fries is relatively minor, approximately 25 percent of total frozen potato production and around 8,000 metric tons. Although Post expects Japan’s frozen potato production to remain stable in the medium term, there is a strong chance that it may decline in the long term as domestic production is expected to shrink.

The top item in volume, of all frozen food products Japanese food processors manufacture, is potato croquettes, which use fresh, frozen, and dehydrated potatoes. Approximately 166,000 metric tons are produced annually. It is expected that production of frozen potato croquettes will continue to be robust in years to come given their convenience.


According to Japanese industry sources, Japanese consumption of frozen potato products is steadily increasing. The majority of frozen potato products are consumed as French fries at fast food restaurants or quick serve restaurants (QSRs), over 300,000 metric tons annually. Hamburger restaurant chains are by far the largest user of frozen French fries. The largest of these chains consumes almost half of total Japanese imports of frozen French fries by itself. Japanese consumption of frozen potato products is closely tied to the performance of QSRs and, as a result, these remain popular as Japanese continue to look for lower-priced meals, given the current sluggish economy.

Japanese convenience stores also sell a fair amount of frozen potato products. Convenience stores have installed full size fryers in stores and sell freshly-fried potatoes to consumers. According to the Japan Franchise Association, there are 47,000 convenience stores in Japan (as of December 2012) and many stores sell freshly-fried potatoes at their shops. The sales of freshly-fried potatoes at convenience stores significantly contributed to overall Japanese demand for frozen potato products.

Compared to fried potato products, consumption of non-fried potatoes is still small. However, as Japan’s population ages and the trend in health-conscious diets advances, the demand for non-fried products is expected to increase in the years to come.

Trade – Imports

In MY 2012/13, Japanese total imports of frozen potato products (including both French fries, HS 2004.10, and non-fried potatoes, HS 0710.10) were 361,705 metric tons, a marginal decrease (less than one percent) from the previous season. The total value of imports was approximately $483 million, same as the previous year. In the long term, as Japan’s potato production is expected to gradually shrink, Post anticipates that imports will steadily grow, given that the overall demand for potatoes continues to be robust.

Approximately 93 percent of Japan’s frozen potato imports are French fries. In the frozen French fry category, the United States is by far the largest supplier to Japan, supplying approximately 80 percent of total French fry imports during the MY 2012/13 season. Japanese imports of U.S. frozen French fries (HS 2004.10) last year decreased by four percent from the previous season to 269,438 metric tons, approximately $362 million.

Sales of U.S. frozen French fries strongly correlated with sales at Japan’s QSRs, particularly hamburger restaurants. Japan’s QSRs are actively introducing new menu items that strongly encourage French fry sales. For example, French fries and soda are relatively low in cost and are often used as a special promotional draw, such as “large size for the price of small.” When consumer spending is sluggish, these promotions become more aggressive, and with the strong yen, imports of frozen French fries increased during the last decade. However, with the recent combination of a weakened yen and an economy showing signs of recovery that started at the beginning of 2013, hamburger chains have become less aggressive in these special campaigns, causing a slight decline in imports for this season. In the medium term perspective, with the expected further advance of QSRs and convenience stores serving French fries, imports are expected to grow further. However, in the long term, market growth is expected to slow considerably as the expansion of QSRs and convenience stores hits its limit, and Japan’s population continues to age and shrink.

Japan's imports of non-fried potatoes are primarily for snack food manufacturing and general food processing. Imports grew dramatically in the last decade for two major reasons: 1) the introduction of popular items using U.S. products by major snack manufacturers; and 2) the expansion in the use of Chinese products by foodservice operators.

As stated above, Japan’s imports of U.S. non-fried potato products are largely supported by Japanese snack food manufacturers who use them to develop new products. U.S. non-fried potato products are processed and frozen in U.S. plants. U.S. potatoes are usually blanched and cut into French fry potato shapes. Then Japanese manufacturers turn them into crispy chips resembling French fries. Other types of U.S. non-fried potato products are blanched and cut into cube shapes in U.S. plants, which the Japanese food service industry then utilizes to prepare various menu items.

According to Japanese industry sources, as a result of the recovery in the domestic crop in MY 2011/12 and MY 2012/13, a major Japanese snack food manufacturer has increased its use of domestic potato products and reduced its volume of imports from the United States. Japanese imports of Chinese non-fried potatoes have steadily increased in recent years, reaching 11,261 metric tons in MY 2012/13. As stated earlier, Chinese products are primarily destined for the Japanese food service sector where they are mixed with other domestic ingredients. Japanese traders report that while the unit price of Chinese potatoes has been slowly increasing, it is still cheaper to buy Chinese products compared to other competitors' products. As a result, price-attractive Chinese potatoes continue to draw Japanese buyers and Chinese potato processers are reportedly fairly adept at meeting the specific needs of Japanese users.

Trade – Exports

In MY 2012/13 Japan only exported a very small amount of frozen potato products (about 150 metric tons) to Indonesia, Hong Kong, Singapore and the United States for sales through local Japanese grocery stores.

Market Trends

As the economic recession has continued over the last decade, Japanese consumers have become highly price sensitive. Japanese QSRs , the key users of U.S. frozen potato products, have been performing well since Japanese consumers have begun to opt for lower-priced menu items. In particular, French fries sales at hamburger chain restaurants have been growing due to special promotions, such as set menus that automatically come with French fries or allow for larger sizes at no additional charge. U.S. frozen French fry suppliers have earned a good reputation among their Japanese clients, as they are able to provide a high quality product and a steady supply throughout the year.

As described in the Consumption section, in recent years, sales of fried potatoes at convenience stores have become highly successful. Today, Japan’s major convenience store chains serve freshly fried potatoes at their stores.

In addition to the robust sales of French fries, in 2007, a major Japanese food manufacturer developed snack food products using non-fried U.S. frozen potatoes (HS 0710.10) as an ingredient. U.S. non-fried potato products are processed and frozen in U.S. plants, and then the Japanese manufacturer processes them into crispy chips resembling French fries, marketing them in small cups. The sales of these products have been very successful, and the product development has expanded to include various flavors. With the improvement in the availability of domestic potatoes in the last two seasons, demand for non-fried U.S. frozen potatoes as an ingredient in these particular products declined. However, Japanese manufacturers anticipate that over the long run, this type of utilization will expand beyond the capacity of domestic supplies, and therefore, they expect the use of U.S. frozen potatoes to continue growing in the future.

Non-fried potato products are widely used by the Japanese food service industry. Family restaurants and “Izakaya,” Japanese style pubs, also prepare food menu items using non-fried potato products. The popularity of “sozai” (prepared food available for purchase at supermarkets and department stores) holds great potential for increasing sales of non-fried U.S. frozen potato products.

The U.S. potato industry has actively expanded its outreach activities to different distribution channels, participating in various trade shows, and promoting fried and mashed potatoes for quick and efficient food preparation at restaurants. It has also demonstrated other types of non-frozen U.S. potato products such as baked, shredded, sliced, and dice-cut potatoes, in addition to highlighting the cost efficiency and nutritive values of using U.S. frozen potatoes. In addition, the U.S. potato industry has worked with local supermarket chains and has been successful in developing new deli menu items using U.S. non-fried frozen potatoes.

The Japanese foodservice industry believes that Japan’s frozen potato market has good potential to grow. Given Japan’s high quality and food safety standards, the United States remains the best positioned country to supply frozen potato products that meet the needs of Japanese food manufacturers and retailers. Targeting alternative segments in Japan’s food service sector, such as supermarkets, traditional Japanese fast food restaurants, and QSRs holds promise for continued expansion of U.S. sales of frozen potatoes in Japan.


Since the last Potato Annual report (October 2012), there have been no major issues relative to U.S. frozen potato products, and Post has observed no trade disruptions of U.S. frozen potato products
