# Miyoshi Smile Trust / 三好スマイル信託

Wiki route: [[trust-banks/INDEX]] -> [[trust-banks/trust-companies-japan-index]] -> [[trust-banks/miyoshi-smile-trust]]

## Overview

Miyoshi Smile Trust is a Fukuoka Finance Branch trust-company row linked to the Miyoshi Real Estate group. In FinWiki it is the Kyushu / Fukuoka real-estate and family-asset trust route.

## Entity Boundary

This page covers 三好スマイル信託株式会社 as the trust-company operator. It should not merge with the broader Miyoshi Real Estate group, property brokerage, or asset-utilization consulting pages.

## Business Role Map

| Route | Reading |
|---|---|
| Real-estate trust | Property management / disposal and land-development trust routes. |
| Family asset planning | Personal trust, inheritance, and donation-adjacent context. |
| Regional route | Kyushu / Fukuoka trust-company coverage. |
| Registry control | Row in [[trust-banks/trust-companies-japan-index]]. |

## Public Context

Miyoshi Smile Trust matters because it closes the Fukuoka Finance Branch row and shows how a local real-estate group can operate a regulated trust-company route. It complements [[trust-banks/kainuma-trust-real-estate]] and [[trust-banks/kiriu-real-estate-trust]].

## Research Checklist

1. Refresh company profile and service pages for license renewal or product changes.
2. Keep real-estate group claims separate from trust-company claims.
3. Link future Kyushu real-estate finance notes to this page only when the company is named.
