about K.K.Fukushima Shoten


Both our head office and factories are located about 20 minutes by car from Aomori Airport (about 10 minutes from the Aomori-Chuo Interchange).
Aomori Prefecture has two brackish lakes that are famous for producing shijimi clams, and our facilities are located roughly halfway between them.
本社、工場ともに青森空港から車で約20分(青森中央インターチェンジから約10分)の位置にあります。
青森県には大和しじみの名産地となっている汽水湖が2つありますが、そのおよそ中間点に位置しています。

We wholesale shijimi clams sourced from production areas, and also perform pre-processing such as sand removal and washing for frozen clams, clam extract, and retort products.
In addition to “Yamato shijimi” clams from Aomori Prefecture, we handle shijimi clams from all over Japan and also import them from overseas.

In Japan, shijimi clams have long been cherished not only for their delicious taste but also for their rich nutritional value.
However, they typically require a long period of sand removal before they can be eaten.
Since this process can easily diminish their freshness, we use retort (pressure-heat sterilization) processing to create products that can be stored at room temperature for extended periods while maintaining their delicious flavor.
日本では昔からしじみ貝は美味しいだけではなく栄養豊富な食材として親しまれてきましたが、通常は長い時間をかけて砂抜きをしないと食べることができません。そして砂抜きをすると鮮度が落ちやすいため、私たちはレトルト処理(加圧加熱殺菌)することで美味しいまま常温で長期間保存のできる商品にしています。

Most of the nutrients in shijimi clams are extracted into the broth.
By turning this broth into a powder, we have created a “dream product” that allows you to easily consume those nutrients anytime, anywhere.
Another feature is that the iron remains in the clam meat, making it suitable even for those who wish to limit their iron intake.
しじみの栄養分はそのほとんどが煮汁の方に抽出されます。それをパウダーにすることで、いつでもどこでも手軽にその栄養分を摂取できる夢の商品が実現しました。別の特徴として鉄分は身のほうに残るため、鉄分の摂取を控えたい方にもおすすめしやすくなっています。

Through years of research and development, we have built a unique production system that transforms the benefits of shijimi clams into convenient, shelf-stable products.
長年の研究開発を経て、しじみの持つ栄養価を、保存性に優れた便利な製品へと昇華させる独自の生産システムを構築しました。
