# Japan IB league table


## Wiki route

This entry sits under [[finance/INDEX|finance index]]. Read it against [[finance/cross-border-m-a-japan|Cross-border M&A Japan]] for peer / contrast context and [[securities/INDEX|securities index]] for the broader system / regulatory boundary.

## TL;DR

Japan investment-banking league tables are ranking tools, not ground truth. The result depends on the vendor, product category, eligible deal universe, announcement / completion date, role credit, and currency conversion. Use them to map competitive position and mandate access, but always record the source vendor and period.

For FinWiki, this page is the interpretation layer for [[securities-firms/goldman-sachs-japan]], [[securities-firms/nomura-hd]], [[securities-firms/daiwa-sg]], [[securities-firms/smbc-nikko]], [[securities-firms/mizuho-securities]], and [[securities-firms/mufg-mums]].

## What Gets Ranked

Source: the table reflects the product categories described by [LSEG Investment Banking League Tables](https://www.lseg.com/en/data-analytics/financial-data/deals-data/investment-banking-league-tables) and the IPO roles described by [JPX](https://www.jpx.co.jp/english/equities/listing-on-tse/new/basic/03.html); vendor methodology and period must accompany any ranking.

| Table type | Typical metric | Why it matters |
|---|---|---|
| M&A financial adviser | Announced / completed deal value and number of deals | Relationship access, cross-border advisory capability, board trust. |
| ECM / equity bookrunner | IPO, PO, CB, equity-linked deal value and number of issues | Capital-markets distribution and issuer access. |
| DCM / bond bookrunner | Bond issuance amount and number of issues | Corporate, financial-institution, and public-sector debt access. |
| IPO lead underwriter | TSE / JPX listing process role, sponsor letter, underwriting role | Startup / growth-company access and retail / institutional distribution. |

## Reading Rules

1. **Record the vendor**: LSEG, Dealogic, Bloomberg, Mergermarket, and company-published tables may classify deals differently.
2. **Record the period**: fiscal year, calendar year, half year, quarter, YTD, announced, or completed.
3. **Separate products**: M&A, ECM, DCM, and IPO underwriting reward different capabilities.
4. **Separate adviser and bookrunner credit**: a bank may advise the board but not underwrite financing, or underwrite without advising on M&A.
5. **Watch parent / JV attribution**: MUFG / Morgan Stanley Japan structures can split credit between [[securities-firms/mufg-mums]] and Morgan Stanley MUFG entities.

## JapanFG Relevance

- [[securities-firms/nomura-hd]] and [[securities-firms/daiwa-sg]]: independent Japanese securities groups.
- [[securities-firms/smbc-nikko]], [[securities-firms/mizuho-securities]], [[securities-firms/mufg-mums]]: megabank-affiliated securities arms.
- [[securities-firms/goldman-sachs-japan]], [[foreign-financial-institutions/bank-of-america-japan]], and [[foreign-financial-institutions/socgen-japan]]: foreign bank / foreign securities competition.
- [[securities/INDEX|securities INDEX]] routes license / brokerage / NISA pages that explain distribution underneath capital markets.

## Decision Use

Use this page when asking:

- who has Japan issuer access;
- whether a bank is strong in M&A advice or only in underwriting;
- whether a ranking reflects one large deal or broad franchise depth;
- whether a domestic or foreign bank is better positioned for cross-border transactions;
- how to compare full-service securities firms with online brokers.
