4. Relationship with parent Ikeda Senshu HD

Ikeda Senshu Holdings is a Kansai regional-bank holding company (TSE Prime 8714) centered on Ikeda Senshu Bank (based in northern Osaka / Hokusetsu). 01 Bank is a digital bank for SMEs (corporations / sole proprietors) that opened on 2025-07-28 as the company’s 100% subsidiary, and serves as the execution vehicle for the digital-bank concept in the medium-term management plan “Vision ‘25” that Ikeda Senshu HD set out in 2020 .

Ikeda Senshu Bank (core / Kansai retail + corporate)
01 Bank (opened 2025-07-28; SME / corporate / sole-proprietor-focused digital bank; this page)

As a regional-bank-affiliated digital-bank opening, it is the 3 th case following Minna Bank BaaS model of Fukuoka FG (FFG) (2021-05) and UI Bank of Tokyo Kiraboshi FG (2022-01) (consistent in Nihon Keizai Shimbun and Nikkin reporting). Whereas Minna Bank was the pioneering retail-oriented full-GCP-cloud example, 01 Bank is a separate axis as a data-credit-focused SME bank that incorporates cloud accounting and SaaS data linkage into lending decisions. It is a competitor / comparison target with a different capital lineage from Minna Bank, not a sister bank.

5. Business model — data-driven SME finance

Aims to utilize business data such as cloud services to reflect, in lending decisions, the actual state of business activity that is hard to see from a financial-statement-centric view
Positioned not as the existing channel of megabanks / regional banks, but as a new data-linked banking model for business operators
Comparison targets: UI Bank, Minna Bank BaaS model, BaaS landscape

6. Peer comparison — lineage of regional-bank digital subsidiaries

Bank	Parent FG	Opening	Target	Architecture
Minna Bank	[[regional-banks/fukuoka-fg	FFG]]	2021-05	Retail
[[regional-banks/ui-bank	UI銀行]]	Kiraboshi FG	2022-01	Retail / small-and-mid corporate
Tonari (BaaS)	[[regional-banks/hokkoku-fhd	北國 FHD]] / CCI	2023-04	BaaS for other regional banks
01 Bank	[[regional-banks/ikeda-senshu-hd	池田泉州 HD]]	2025-07	SME / corporate / sole proprietor

FFG does not have an SME-focused 01 Bank in addition to retail (Minna Bank); 01 Bank is an independent 3 regional-bank digital bank in the Ikeda Senshu HD lineage. Hokkoku FHD takes the “BaaS wholesaling” route, Kiraboshi the “single digital bank (UI Bank)” route, and Ikeda Senshu HD the “SME / sole-proprietor-focused (01 Bank)” route — their paths diverge.

7. Supervision / regulation

Supervisor: Financial Services Agency (FSA), Kinki Local Finance Bureau (per the head-office location in Suita City, Osaka Prefecture)
Business type: ordinary bank under the Banking Act
Deposit insurance: member of the Deposit Insurance Corporation (ordinary deposits protected up to 1,000万円)
Data credit: triple constraint of the Personal Information Protection Act + the FIEA (use of credit information) + lending governance under the Banking Act

9. Open questions

To what extent will the 2025年 / 2026年 fiscal-year account-count / loan-balance / ordinary-profit disclosures of 01 Bank be detailed in parent Ikeda Senshu HD’s consolidated IR? (Ikeda Senshu HD is reported to aim for “single-year profitability in 3 ”)
Will the default-rate track record of the data-credit model be disclosed? What is its advantage relative to industry benchmarks (SME-lending default rates of mega / regional banks)?
Relative to the preceding Minna Bank (retail) / UI Bank (retail / small-and-mid corporate), will 01 Bank’s SME / sole-proprietor focus function as differentiation?
What are the possibilities for competition / cooperation with Hokkoku FHD’s Tonari (BaaS) and other regional-bank digital subsidiaries?
What is the concrete contractual structure of the partner data sources (freee / Money Forward, etc.)?

[!info] Parent company / lineage corrected (2026-05-30) The old version stated the parent company as Fukuoka FG (FFG) and described “an FFG 2 digital-bank structure alongside Minna Bank” and “opened 2024-02 ”, but both are erroneous. Correctly, parent company = Ikeda Senshu Holdings, Inc. (100%), banking license granted 2025-02-28, opening 2025-07-28. 2024-02 is the establishment date of the opening-preparatory company (01Bank Establishment Preparatory Co., Ltd.). As a regional-bank-affiliated digital bank, it is the 3 th case following FFG Minna Bank (2021-05) and Tokyo Kiraboshi FG UI Bank (2022-01), and is a competitor with a different capital lineage from Minna Bank, not a sister bank (confirmed consistently in Wikipedia / PR TIMES / Nihon Keizai Shimbun / Nikkin). The frontmatter tags, head office, sections 4 / 6, chronology, and Related have all been corrected.
