The promise
A formal written demand that sets out the facts, the basis for your claim, and the resolution you are asking for — in a tone measured enough that the relationship can continue afterwards if that is what both sides want.
The problem
Informal contact has been tried and has not resolved the matter, or has stopped producing any response at all. At this point, an email from your own address can start to feel repetitive rather than persuasive, and something more formal is needed to move things forward.
The solution
The letter covers the factual sequence of events, the contractual or statutory basis for your position, the resolution being sought, and a reasonable period for response — set out in language that is firm without being combative.
The experience
Your side of the channel
You provide the background and any prior correspondence, and confirm the outcome you are seeking.
This office's side
A draft is prepared, reviewed with you once, and finalised, along with a note on delivery and the responses this kind of letter commonly receives.
The investment
¥18,500
This covers one document with one revision round, completed within two weeks, plus advice on delivery method and typical responses.
The proof
A formal demand often prompts a response where informal contact has not, simply by signalling that the matter is being taken seriously. Timelines and outcomes vary by case, so realistic expectations are set out alongside the letter rather than promised in advance.
The assurance
Sending a written demand does not commit you to mediation or litigation. It is one stage among several, and the decision on what follows remains yours.
Next steps
Send a message describing the background and the outcome you are seeking, and a draft can be prepared for your review.
