'Mitsubishi, Mitsui, Sumitomo as Culture' Reaches 7th Print Run, Surpassing 19,000 Copies! Full of Unwritten Rules You Should Know, Such as 'Serve Kirin Beer at Mitsubishi Group Receptions'!

Asukashinsha Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Naohisa Doi) announced that its book 'Mitsubishi, Mitsui, Sumitomo as Culture' (authored by Kiyohiro Yamakawa) has been decided for its 6th print run due to strong sales!

The author, with over 30 years of experience as an economic magazine journalist, has utilized his extensive knowledge to conduct a comprehensive investigation, covering essential knowledge about Mitsubishi, Mitsui, and Sumitomo!

"When entertaining Mitsubishi-affiliated companies, you must serve Kirin Beer."

Have you ever heard of such a "rule"?

In fact, Kirin Beer is a part of the Mitsubishi Group. If you are conscious of the "group," finding a place that handles Kirin Beer is an important skill for a business person.

Conversely, if you choose a venue that handles Sapporo Beer, which is Mitsui-affiliated, for a reception... while that alone may not decide everything, you might be perceived as someone who "doesn't understand."

In this way, the three major groups of Mitsubishi, Mitsui, and Sumitomo have many "origins and relationships that business people should know."

This book covers the history of the three major groups, as well as detailed information on their main companies, including their origins, relationships, rankings based on "numbers" such as current stock prices and employee numbers, and even rankings of employees by university. It is truly a "cultural book" that provides comprehensive explanations of each group.

Why does Mitsubishi emphasize "organization"? Why does Mitsui have a "free atmosphere"? Why does Sumitomo feel a "strong bond"? By understanding the history of each group, you can gain a deeper understanding of their characteristics.

Recommended by Azabu Keibajo, author of 'Reiwa Gannen no Jinsei Game'!

"I wish I had read this during my job hunt!"

"History and geopolitics... An amazing book that verbalizes the 'atmosphere' of the Japanese economy."

This is a business textbook for those entering society and those working in the core of Japan's business world! It is full of knowledge that you "think you know but don't."
