# FINX JCrypto株式会社 — 日本暗号資産交換業者

## Wiki route

This entry sits under [[exchanges/INDEX|exchanges index]]. Read it with [[exchanges/fsa-vasp-registration-system|FSA 暗号資産交換業登録制度 — 番号体系・財務局管轄・登録要件]] for adjacent context and [[fintech/japan-financial-regulation|日本金融規制 — トークン・暗号資産・決済に関する法体系]] for the broader system boundary.

> FSA 登録番号 関東財務局長 第00012号 · 登録日 2017-12-01

## TL;DR

FINX JCrypto is a registered Japanese crypto asset exchange operator. The FSA list dated 2026-04-01 shows registration number Kanto Local Finance Bureau No.00012 and lists BTC, ETH, XRP, XLM, BCH, DAI, DOT, LTC, SHIB, OAS, ADA, AVAX, BNB, DOGE, PEPE, POL, SOL, and TRX.

For FinWiki, this is a cleanup page: the operator exists in the official FSA list but was missing from the previous exchange entity coverage.

## 2. 取扱通貨

The 2026-04-01 FSA registry row lists BTC, ETH, XRP, XLM, BCH, DAI, DOT, LTC, SHIB, OAS, ADA, AVAX, BNB, DOGE, PEPE, POL, SOL, and TRX. This is a dated registry disclosure; current order, deposit, and withdrawal availability must be checked in the service and contract documents.

## 3. 業務範囲

The public company-facing surface is narrower than many retail exchanges. The official company page emphasizes crypto-asset exchange registration and real-estate / crypto-asset transaction adjacency. Treat this as a licensed operator page, not as evidence of high retail-exchange market share.

## 4. 戦略動向

- **Real-estate adjacency**: Public materials position the company near real-estate value creation and crypto-asset settlement.
- **Public positioning**: Official materials present the Coin Estate service and real-estate / crypto-asset transaction adjacency. This differs in public positioning from broad consumer brands, but it does not establish a market-share rank. Real-estate × token adjacency belongs in the [[exchanges/rwa-tokenization-cex-integration|RWA tokenization × CEX 統合]] discussion.
- **Registry completeness**: The main reason to include this page is to avoid gaps against the FSA registered-operator list.
