History of Innovation

1996 New Oji Paper and Honshu Paper merged

The Oji Group's origins in corrugated container date back to 1924, when it began
manufacturing at Morishigyo. In the 1950s, with the advent of the "Age of Production"
the market expanded rapidly, and the Kushiro Mill (formerly Honshu Paper) wasopened. While enhancing functionality through development, we have increased
production through the development of afforestation and chip manufacturingbusinesses and mergers with corrugated container manufacturers, and have built asystem that handles everything from raw material procurement to processing. Our
business activities cover a wide range of fields including food, beverages, agriculturaland marine products, home appliances, and disaster prevention-related products.

2001 Oji Container Co., Ltd. was founded2005 Oji Container and Chiyoda Container merged to form Oji Chiyoda Container Co., Ltd.
2005 Morishigyo Co., Ltd. was acquired
2011 Oji Container's Sendai and Fukushima mills were damaged by the Great East Japan Earthquake

1967

2012 Merged with Shizuoka Oji Container to form Oji Container Co., Ltd
2020 Chiba Office (Funabashi Plant), Morishigyo started operation
2023 Tochigi Plant, Oji Container started operation

1959

Development of colored and White Top
LinerMori corrugated container plant was established.
Started production of corrugated container.

Adoption of "High Bright Liner," ahigh brightness corrugatedcontainer made from waste
newspaper

Entry into containerboard by former
Honshu Paper

Establishment of production system fromraw materials to containerboard

Promotion of the shift to corrugatedcontainer for fruit/vegetables packaging

1982

1976

The Oji Group has established a production
system from chips to containerboard, using
softwood chips made from thinned timber in
Hokkaido and hardwood chips produced by
JANT established in Papua New Guinea as rawmaterials.

Proposal and creation of unified design
Adoption of "DPC",
freshness-preserving corrugated container

Installation of flexo rotary press

100% recyclable moisture-proof corrugatedcontainer with a high moisture-proofing property
and evaporation-preventing effect of water
vapor, etc. It keeps fruit/vegetables fresh. It isalso used as an outer box for copying paper
because of its excellent moisture barrier effectfrom the outside.

Advanced use of recovered paper

Changes in the logistic services environment and improvements
in corrugated container processing technology have reduced
strength requirements for containerboard, leading to lower
grades of linerboard. At the same time, the price of wood wasskyrocketing, and we turned to waste paper as a solution. In
1976, the Kushiro Mill started using waste paper. We havesucceeded in improving the quality of waste paper pulp andincreasing production by a significant expansion of its waste
paper for corrugated waste paper processing facilities andintroducing a DIP facility for waste newspaper.

2013

Developed "Chaba Board",
corrugated container containing tea leaves(linerboard is produced by another company on an OEMbasis)

Development of water-repellent andwater-resistant Liner"DIET BOX", a box shape that prevents box
bulging, adopted for beverage cases”USPC (Ultra Super Protect Container)”used as cool boxes at events
100% recyclable ultra water-resistantcorrugated container that replaces styrofoamand plastic. Ideal for refrigerated and frozen
foods, products used during rainfall, cases
where products are packaged with water, orcases used under harsh conditions, such aswith ice.

Development and provision of corrugatedcontainer beds for disaster relief

Packaging system business initiatives

The high economic growth of Japan led to a growing
demand for more automated and efficient packaging,which led to the development of packaging systems formilk and lactic acid beverages in the 1970s, andcorrugated container assembly and sorting systems in the1980s. We actively developed its integrated packaging
business, from outer packaging to interior and individual
packaging, and its packaging system business, whichmakes full use of all packaging materials, including
corrugated container, folding cartons, and plastic film.

Digital printing of corrugated container
A new digital printing press is now available forprinting corrugated container, where flexo printing
is commonly used. Printing directly from data topaper eliminates the need for printing plates,
enabling cost reductions and small-lot production.
The inkjet method also enables precise andexcellent printing expression, contributing to theimprovement of corrugated container's aestheticaspect.

Started production and sales of "Rakudan"(continuous corrugated cardboard)
