What Yangjisa does
Yangjisa Co., Ltd. (주)양지사 is a South Korea-based diary and stationery manufacturer founded in 1976 by Bae Goo Lee and headquartered at Gimpo Gold Valley in Gimpo-si, Gyeonggi-do. The company designs and produces a portfolio centered on the Yangji (양지) flagship diary brand, complemented by sub-brands Dilusso (lifestyle accessories), SOFICE (SMB B2B diaries), Banda (pet diaries, co-developed with GS Retail), Super Eraser (brain-training journal), and the recently launched Yangji Solution Smart Pen and The Cloud Note (digital note synchronization). Manufacturing is supported by KOLBUS automated cover-making and casing-in lines, Heidelberg offset presses, AGFA/Heidelberg CTP (Computer-to-Plate) systems, an HP Indigo 7500 7-color digital press, and ERP-driven order management, with a stated daily production capacity of 200,000 units on a ~33,000 m² factory site. Yangjisa has been listed on KOSDAQ since October 1996 and holds ISO 9001:2000 / KSA 6001:2001 certifications.
The company generates revenue through a multi-channel model: customized OEM diary production for 1,000+ corporate and public institution accounts, domestic retail distribution to 500+ accounts (large discount stores, bookstores, franchises), export to 200 companies across 30 countries, consignment operations at 16 Youngpoong Bookstore locations under the Bander section, GS Retail/Lalavla H&B store distribution, and direct e-commerce via yangjimall.com, yangjigift.com (B2B gifting), SOFICE, and Naver Smart Store.

Yangjisa competitors and assessment
Company assessmentDirect peers
- Filofax: British originator of the personal organizer/planner with ring-binder systems; directly comparable as a maker of dated planners, account books and organizational stationery that compete for the same corporate and consumer planning use case.
- Castelli: Italian premium notebook manufacturer producing dated and undated diaries/journals; comparable as a European heritage maker of hardcover stationery sold through boutique and corporate channels.
- Paperblanks: Premium hard-cover journal and diary publisher known for decorative covers; directly competitive in the premium gifting and self-purchase hardcover diary segment where Yangjisa competes internationally.
- Quo Vadis: French-origin planner and academic diary specialist now under Exacompta-Clairefontaine; closely comparable as a dated planner manufacturer serving both personal and institutional (school/corporate) markets.
- Leuchtturm1917: German premium notebook and planner manufacturer with comparable numbering system and hardcover craftsmanship; the closest European peer to Yangjisa's Yangji line in terms of build quality, customization, and B2B/personal diary use cases.
- Hobonichi: Japanese maker of premium planners and diaries with a cult global following; directly comparable premium daily/weekly diary product positioning targeting both consumers and corporate gifting, with very strong export culture analogous to Yangjisa's.
- Rhodia: French premium paper goods brand (pads, notebooks and planners); comparable in the premium-pad and notebook category and competes for the same stationery-literate buyer that Yangji serves at the high end.
- Midori: Japanese manufacturer of premium MD paper notebooks and stationery accessories; directly comparable as an Asian heritage paper stationery maker exporting globally with strong craftsmanship positioning.
Broad incumbents
- Moleskine: Global premium notebook and planner incumbent (now part of the D'Ieteren group); directly overlapping in hardcover diaries, notebooks and lifestyle stationery, and competes for the same premium corporate-gifting and retail shelf space Yangjisa targets.
Regional players
- Monami: Major Korean stationery manufacturer (pens, markers, notebooks) listed on KOSDAQ; the closest domestic peer in scale and channel, sharing Korean mass-market retail and corporate accounts but with a much broader writing-instrument focus.
