# Japan ABS market overview — reproducible evidence guide

## TL;DR

This page no longer ranks Japanese securitization products, issuers, vehicles, ratings, dealers, investors or annual volumes without a defined dataset. JHF MBS has a dedicated public series; other products must be measured from JSDA's stated categories and named transaction records. Public offers, private placements, holdings and cross-border transactions must not be combined into one market-size hierarchy.

## Wiki route

Use [[structured-finance/japan-securitization-product-matrix]] for product evidence boundaries and [[structured-finance/jhf-mbs-mechanics]] for JHF mechanics.

## 1. Product measurement

[JSDA's securitization-market survey](https://www.jsda.or.jp/en/statistics/securitization-market/) and [JHF's dated issuance history](https://www.jhf.go.jp/files/topics/5014_ext_99_1.pdf) support the following measurement table.

| Measure | Public source | Rule |
|---|---|---|
| JHF MBS issuance | JHF series history | State product, series and period |
| Securitization issuance | JSDA survey | Preserve category, period and revisions |
| Named ABS / RMBS / CMBS | Issuer, offering or rating record | State public/private disclosure boundary |
| Bank structured-credit exposure | Named bank disclosure | Report as holdings, not issuance |
| Cross-border deal | Foreign issuer / offering record | Do not classify as Japanese domestic issuance solely because a Japanese investor participates |

## 2. Transaction roles

[JCR's public rating list](https://jcr.co.jp/en/ratinglist/sf_sf/) can identify named rated transactions; the following table states the evidence needed for each role.

| Role | Required evidence |
|---|---|
| Issuer / originator | Offering, trust or rating document |
| Arranger / dealer | Named transaction announcement or offering document |
| Trustee / account bank | Trust and transaction documents |
| Servicer / backup servicer | Servicing agreement or rating report |
| Rating agency | Dated class-specific action |
| Investor / allocation | Public allocation disclosure, if available |

No dealer or agency market-share conclusion is retained.

## 3. Historical analysis

[JSDA's survey](https://www.jsda.or.jp/en/statistics/securitization-market/) supports the following reproducibility checklist.

| Field | Required treatment |
|---|---|
| Period | Exact start / end dates and survey version |
| Category | Source definition and inclusions |
| Amount / count | Cited table and revision status |
| Public / private boundary | State known omissions |
| Trend | Show calculation separately from source fact |
| Default / loss | Use named trustee, servicer or rating actions |

## 4. Rating, structure and pricing

[JCR's methodology library](https://www.jcr.co.jp/en/rrinfo/meth_sf/) is an analytical source, not proof of a particular market convention.

| Claim | Required evidence |
|---|---|
| Vehicle | Named legal documents |
| Tranches / enhancement | Named waterfall and closing balances |
| Rating | Named class, date and criteria version |
| Spread | Dated pricing result and benchmark |
| Investor base | Public allocation / holdings disclosure |
| Market rank | Defined population, period and calculation |

## 5. Deferred claims

“Largest,” “dominant,” “typical vehicle,” standard AAA outcome, annual volume bands, investor clusters and post-2008 / 2020 revival narratives remain deferred unless reproduced from a defined public dataset or named transaction set.
