Marui Foods

Marui Foods traces its roots to "Ito Konnyaku Shop," founded in Tsuruoka in October 1952. The business later became Marui Shokuhin Co., Ltd., and steadily built a manufacturing and logistics base through relocations, new facilities, and warehouse expansion — always in service of the region's daily meals.

Their message is consistent: deliver food that is safe, trustworthy, and more delicious. Traditional staples like tofu, fried tofu, konnyaku, and similar foods remain essential not only because they adapt to countless recipes, but also because they support healthy everyday eating — an idea Marui treats as a central responsibility.

What makes the brand especially compelling is its commitment to ingredients. Marui revived fields that had become wild and unusable, then restored fragile konnyaku potatoes after years of experimentation. It's a very practical philosophy: great konnyaku starts with great potatoes — pursued hand-in-hand with the community.

The lineup reflects Shonai's seasons. Tama-konnyaku is enjoyed throughout the year; summer brings the cool, smooth texture of "Nanzenji" tofu; autumn is imoni season — Shonai's miso-based version with pork, plus a soy-sauce version with Yamagata beef; winter features oden where the star is "aji-shimi konnyaku," deeply infused with broth and perfectly suited to cold weather.

Behind the scenes, Marui has continued to modernize its production foundation, including wastewater treatment facilities and expanded operations that support prepared foods. The company also obtained Organic JAS certification (2000), reflecting ongoing attention to quality and process.

Today, Marui's products are available through major retail partners and via its online shop — bringing Shonai's everyday comfort foods beyond the region. The appeal isn't flashy; it's the reliability of true staples, made with care.

A legacy that began as a konnyaku specialist (since 1952)

Marui's story started as "Ito Konnyaku Shop" in Tsuruoka (October 1952). Over time, the company evolved into Marui Shokuhin Co., Ltd., expanding its production base and product lineup while staying rooted in the region's everyday food culture.

Ingredient-first thinking — starting from the konnyaku potato

To make truly good konnyaku, you need truly good konnyaku potatoes. Marui revitalized overgrown, neglected fields and brought back delicate konnyaku potatoes through years of trial and error — pursuing better ingredients together with the local community.

Seasonal Shonai flavors, captured in familiar staples

Yamagata's tama-konnyaku is enjoyed year-round — both as a side dish and a skewer snack. In summer, "Nanzenji" tofu signals the season in Tsuruoka; in autumn, imoni (taro hot pot) shines — Shonai-style with pork and miso, and also a soy-sauce version with Yamagata beef. In winter, their oden features deeply soaked "aji-shimi konnyaku," a comforting snow-country classic.

An online shop that also cares about gifting details

Marui launched online shopping after opening its website (2001). Gift sets, noshi, and wrapping are available, with thoughtful handling such as sending payment slips to the purchaser — not inside the gift shipment — so gifts arrive clean and considerate.
