Our firm began shortly after the end of the war by founder Yoshiji Kawaguchi with a trade in cotton rope and the like, based in Tottori City’s Suehiro Onsen-cho. From there it proceeded into prefectural manufacture and sales of packaging for 20th-century pears, and expanding into the 20th-century pear market nationwide. Afterwards business came to encompass agricultural materials in general, which continues today, including the furnishing of foodstuffs to JA Tottori.

In recent years, our Nosaka plant in Tottori City manufactures and provides original strawberry trays and every manner of packaging products for Tottori Takuminomori Kobo. Our goal is to be the ‘agricultural total solution’ meeting regional producers’ needs for seeds, fertiliser, and facility support.

We also provide a comprehensive packaging materials service, offering everything from suggestions for individual enterprises to delivery. Taking the needs of every client into account, we provide a host of environmentally-friendly products that are both high performance and low-cost.

We take a proactive approach to the overseas market, our basic concept being to deal directly with individual firms without a middleman, furnishing our merchandise directly for a competitive advantage over other manufacturers while providing a distinct product line.

The Kawaguchi Group’s positions its marketing division at the core of its enterprise, with its strategy to plan business five years in advance. Well attuned to trends in the domestic market, we are always ready to make changes.

RIVERD Corporation Inc. is truly based on the catchphrase ‘wrapping up the future’, always striving for value in unique, original packaging and other original commodities, with new products under development every day.

Kawaguchi Group: The Symbol of a New Era
Tottori has the Chance to Pursue a New Market

In June of 2016, Kawaguchi Group made its advance into North America.
We are currently around the globe trading in the following products and industries:
  ・Electrical machinery and equipment manufacturing
  ・Import and sales of agriculturals
  ・Import and sales of pet food

We believe the knowhow and commodities used to make our products will lead to the world knowing that our goods are “Made in Japan” or “Made in Tottori.” In order to demonstrate how a company from Tottori will become popular throughout the world, we are now daring to enter into a new stage.

The advancement of the Kawaguchi Group into North America has begun on the West Coast of the United States, along the frontier adjacent to the twin cities of San Diego (USA) and Tijuana (Mexico). The border zone between the US and Mexico has historically maintained a strong economic connection, especially since NAFTA (North American Free Trade Agreement). After NAFTA went into force in 1994, economic integration advanced rapidly throughout the region.

RIVERD USA’s main office is in the city of San Diego, located at the southern end of the state of California. San Diego’s warm, mild climate all year long makes it a very comfortable place to live. Although it has the convenience of being the eighth-largest city in the U.S., it enjoys a unique coexistence with the rich natural environment that surrounds it. In recent years, not only American but Japanese, Korean, and Taiwanese companies have established factories across the border on the Mexican side. Therefore, there has been a growth in the number of expatriates from these Asia-based companies who reside in San Diego and enjoy the sunny, laid-back lifestyle of southern California.

The city of Tijuana is at Mexico’s northernmost point and is the largest city in the state of Baja California. It is about 15-20 minutes by car from San Diego to Tijuana, so the cities are positioned quite close to each other.
We are now operating a business in lithium battery processing. Japanese expatriate staff living in the local area oversee production assembly as well as quality control. In order to fulfill the same level of QCD as our domestic production in Japan, we provide support using the concentrated knowhow cultivated within the corporate group. Also, automated production equipment has been shipped overseas from Japan to our production facility in Tijuana to ensure that we achieve a certain level of production volume even at this early stage.

RIVERD Field Agricultural Corporation Inc. Crop Cultivation and Sales

Energize Tottori Via Agriculture!!

RIVERD Field Agricultural Corporation Inc.

At Riverd Corporation, we were only selling packaging materials. But then we discovered Tottori Prefecture’s unique strawberry “Berrybird (Totteoki)” and were attracted to its deliciousness. This variety can only be grown in Tottori, so we launched a new agricultural corporation and decided to establish our own farm.

Taking advantage of the fact that this unique strawberry can only be grown in Tottori, we will sell it as a high-value-added product inside and outside the prefecture. In the future, as an agricultural corporation we will take on the challenge of growing not only strawberries, but a wide range of crops.
