# JIA Trust / JIA信託

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

## Overview

JIA Trust is an operating-type trust company under the Japan Investment Adviser group route. Its public materials emphasize tailor-made trust products, aircraft operating-lease assets, real estate, cash, and securities-related trust-property categories.

## Entity Boundary

This page covers JIA信託株式会社, not the full [[securities/financial-instruments-business-operators-japan-index|financial-instruments operator]] surface of the broader JIA group. Use this page for trust-company classification and structured-asset custody / administration context.

## Business Role Map ^[JIA 信託 公式サイト: https://www.jiatrust.co.jp/; 金融庁の現行免許: https://www.fsa.go.jp/menkyo/menkyoj/sintaku01.pdf]

| Route | Reading |
|---|---|
| Aircraft leasing | Trust route for aircraft operating-lease assets. |
| Real estate | Trust property route for real-estate-related products. |
| Group boundary | Parent is Japan Investment Adviser, but this page is the trust-company entity. |
| Registry control | Row in [[trust-banks/trust-companies-japan-index]]. |

## Public Context

JIA Trust is useful because it connects the trust-company registry with asset-finance structures rather than retail estate planning. It is also a clean comparator for [[trust-banks/capital-trust]] and [[finance/japan-acquisition-finance|asset-finance]] pages.

## Research Checklist

1. Track any JIA group disclosure on trust-product scale or assets under administration.
2. Keep leasing-product details source-bound and avoid inferring fund economics.
3. Link future aviation-finance notes back to this route only when JIA Trust is explicitly involved.
