CRANE CONSULTATION HOUSE — Since 2004

Design the structure.
Build the business.

From business design to sales, promotion, and AI implementation.

CRANE CONSULTATION HOUSE works as a small team alongside owner-led companies. We organize field knowledge, propose new businesses, build the promotional website and sales path, and move quickly toward the first paying customer.

How I work.

Yukichi Ito — business architect and investor

I am a consultant and investor who designs the structure of businesses. I draw on neurophysiology and the psychology of perception to organize how a company, its customers, and its decision-makers understand a problem.

For more than twenty years I have worked on one question: why does a business hold together? I look at both the numbers and the structure by which a company functions in society, then connect that structure to sales activity, promotion, operations, and implementation.

I joined the management of Kanko Yuchi Inc. (観光誘致株式会社) in 2018 and was responsible for the business as a whole. I served as representative director from 2021 and sold my shareholding in March 2025.

In 2026 I organized this work as CRANE CONSULTATION HOUSE (伊藤雄吉相談所). Today we provide three separate forms of support—collaborative business development, ongoing advisory, and spot consulting—alongside investment, free learning resources, and practical classes.


Three separate ways to work together.

Our priority is collaborative business development: the Consultation House team joins the field and helps build a new business, not just a plan. Previously offered only to existing partner companies, this service is now open to a small number of new collaborations as our team grows.

Work on management continuously

Ongoing advisory

Custom monthly engagement

Regular sessions covering business design, sales, promotion, organization, and AI adoption. For companies that want an ongoing outside perspective on decisions and execution.

Discuss advisory support

Focus on one decision or problem

Spot consulting

¥50,000/ hour, before tax

A focused session for management questions, business-model review, revenue structure, sales initiatives, or a new-business idea. We clarify the situation and decide the next concrete action.

Build a business with AI.

We publish the material needed to build a business with AI for free. The SOVREN Framework covers company information, customer understanding, business planning, communication, promotional websites, revenue models, and the division of work between people and AI.

You can read the web materials without registering. For people who need help applying them to their own company, practical classes are also available in online and in-person formats.

Some educational programs that use this framework are operated by partner organizations. AIP School is operated by Seedhouse, Inc.; Yukichi Ito contributes to its business design, learning materials, and use of AI. It is separate from CRANE CONSULTATION HOUSE.

The weekly live series, One-Person Company Report, reviews the numbers, actions, decisions, and current obstacles behind the Consultation House, its collaborations, and its free learning resources.

Get in touch.

For collaborative business development, ongoing advisory, spot consulting, investment, or the SOVREN Framework, contact us by DM or email. Tell us briefly who you are and what you want to move forward.

You do not need a polished proposal. A short explanation of your company, the current situation, and the project or problem you want to address is enough to start.
