How It Works
From Analog to Digital
AI Consulting
Applying AI to your business can deliver the following benefits.
Easing Labor Shortages
By letting AI take over part of the work previously done by people, you can offset labor shortages — reducing workloads while executing tasks faster and more accurately than manual work.
Greater Efficiency
AI is also a powerful productivity tool. By collecting and analyzing behavioral data from visitors to your website, you can quickly and automatically read market demand.
Lower Personnel Costs
With improved efficiency, the same volume of work can be handled by fewer people. Freed-up resources can be redirected to new ventures that raise enterprise value.
RPA Consulting
Four benefits of introducing RPA tools.
Efficiency & Productivity
Automating manual checking work dramatically improves speed and accuracy — freeing staff to focus on creative work like sales and business planning.
Cost Reduction
Fully automating labor-intensive tasks can substantially cut personnel costs, and reduces non-value-adding costs such as paper-based processes.
Greater Accuracy
RPA is software — it doesn't make mistakes in fixed routines. It excels in error-intolerant work such as accounting checks.
Better Resource Allocation
Staff freed from routine tasks can be reallocated to more productive work, enabling optimal distribution of management resources.
M&A Consulting
The Guardian of M&A.
Owners considering a sale often don't know which intermediary — or which advisor — to trust. Meanwhile, intermediaries face uneven capabilities across their staff. We act as a trusted advisor to business owners, connecting them with the right M&A intermediaries and advisors, supporting succession solutions and growth strategies, and providing consulting to intermediaries to raise standards across the industry.
After wealth management work at a foreign bank, joined Nihon M&A Center Inc. in 2012, achieving top-class contract and closing numbers as a sell-side advisor. Seconded to Nomura Securities in 2016, then worked in the company's securities division (now the financial alliance division) and helped launch the Fukuoka branch, involved in over 100 closings, mainly in manufacturing. In 2018, participated in launching Japan Investment Fund Co., working from deal sourcing to investment decisions, execution, and hands-on value creation. Later founded Rin LLC as representative. Provides flat, sell-side-oriented advice — without conducting intermediary business itself — introducing suitable M&A intermediaries and consulting for intermediaries and PE funds.
Subsidy Application Support
Japan offers many subsidies — business restructuring, monodzukuri (manufacturing), sustainability subsidies for small businesses, and more. Knowing whether you qualify and where to start is not easy while running a business, but a successful application can be a major boost. Our group includes CPAs, tax accountants, SME management consultants and business consultants who support you from application through post-adoption operation.
Our Group's Consulting Philosophy
“To be a part of our clients' growth.”
“How much did our clients need us?” — that is our standard. Beyond responding to requests, we build relationships where clients can bring even emotional concerns seemingly unrelated to technical expertise, and provide high-value support grounded in both reason and empathy. We aim to be the trusted right hand that lets you focus on your business with peace of mind.
