Accounting Policies [Abstract]
Interim Financial Data	Note 1 – Interim Financial Data Basis of Presentation The information furnished in these unaudited interim financial statements for the three and six months ended September 30, 2015 and 2014 has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In the opinion of management, the unaudited financial information reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The results of operations for the three and six months ended September 30, 2015 do not necessarily indicate the results which may be expected for the full fiscal year ending March 31, 2016 (“fiscal 2016”). These financial statements should be read in conjunction with the Consolidated Financial Statements, significant accounting policies, and other notes to the Consolidated Financial Statements included in Toyota Motor Credit Corporation’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended March 31, 2015 (“fiscal 2015”), which was filed with the Securities and Exchange Commission on June 2, 2015. References herein to “TMCC” denote Toyota Motor Credit Corporation, and references herein to “we”, “our”, and “us” denote Toyota Motor Credit Corporation and its consolidated subsidiaries. Certain prior period amounts have been reclassified to conform to the current period presentation. Related party transactions presented in the Consolidated Financial Statements are disclosed in Note 14 – Related Party Transactions of the Notes to Consolidated Financial Statements. Assets Held-for-Sale As of August 31, 2015, we reclassified certain assets and liabilities related to our industrial equipment retail, lease and dealer portfolios (hereinafter the “commercial finance business” or “disposal group”) to held-for-sale as all of the following criteria were met: management, having the authority to approve the action, committed to a plan to sell the disposal group; the disposal group was available for immediate sale in its present condition subject only to terms that are usual and customary; we located a buyer; the sale of the disposal group was determined to be probable, and transfer of the disposal group was expected to qualify for recognition as a completed sale within one year; the disposal group was actively marketed for sale at a price that was reasonable in relation to its current fair value; and actions required to complete the plan indicate that it was unlikely significant changes to the plan would be made or that the plan would be withdrawn. We initially measure a long-lived asset or disposal group that is classified as held-for-sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group, less any costs to sell, each reporting period it remains classified as held-for-sale. We report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held-for-sale. Cash flows associated with the assets held-for-sale are reflected as investing activities within the Consolidated Statement of Cash Flows. See Note 8 – Other Assets and Other Liabilities of the Notes to Consolidated Financial Statements for additional detail. Note 1 – Interim Financial Data (Continued) New Accounting Guidance In May 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the recognition of revenue from contracts with customers. This comprehensive standard will supersede virtually all existing revenue recognition guidance. This standard applies to all contracts with customers except leases, insurance contracts, financial instruments, guarantees, and certain nonmonetary exchanges. In August 2015, the FASB issued a one-year deferral of the effective date, with early adoption as of the original effective date permitted. We expect to adopt the new guidance on its deferred effective date, which is April 1, 2018 for TMCC. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In February 2015, the FASB issued new guidance that amends the analysis a reporting entity must perform to determine whether it should consolidate certain legal entities. This accounting guidance is effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued new guidance that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. In August 2015, the FASB issued an additional update which clarifies that debt issuance costs for line of credit agreements may continue to be deferred and amortized. This accounting guidance will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued new guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. While similar guidance exists under current US GAAP for cloud service providers, this update provides explicit guidance for a customer's accounting. This accounting guidance will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In May 2015, the FASB issued new guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. This accounting guidance is limited to footnote disclosure and will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In May 2015, the FASB issued new guidance that requires additional disclosures related to short-duration insurance contracts. This accounting guidance will be effective for us for the annual period beginning April 1, 2016 and for interim periods within annual periods beginning April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. Recently Adopted Accounting Guidance In April 2015, new FASB accounting guidance became effective that amends the requirements for the reporting of discontinued operations and requires certain additional disclosures. Under the new guidance, only disposals that represent a strategic shift and that have (or will have) a major effect on an entity’s operations and financial results should be presented as discontinued operations. This guidance was adopted by us in August 2015 when we reclassified certain assets and liabilities related to our commercial finance business as held-for-sale. As the sale of our commercial finance business did not represent a strategic shift that will have a major effect on our operations and financial results, it did not meet the criteria to be presented as a discontinued operation. Our adoption of this guidance did not have a material impact on our consolidated financial statements.

Note 1 – Interim Financial Data

Basis of Presentation

The information furnished in these unaudited interim financial statements for the three and six months ended September 30, 2015 and 2014 has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In the opinion of management, the unaudited financial information reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The results of operations for the three and six months ended September 30, 2015 do not necessarily indicate the results which may be expected for the full fiscal year ending March 31, 2016 (“fiscal 2016”).

These financial statements should be read in conjunction with the Consolidated Financial Statements, significant accounting policies, and other notes to the Consolidated Financial Statements included in Toyota Motor Credit Corporation’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended March 31, 2015 (“fiscal 2015”), which was filed with the Securities and Exchange Commission on June 2, 2015.

Certain prior period amounts have been reclassified to conform to the current period presentation. Related party transactions presented in the Consolidated Financial Statements are disclosed in Note 14 – Related Party Transactions of the Notes to Consolidated Financial Statements.

Assets Held-for-Sale

As of August 31, 2015, we reclassified certain assets and liabilities related to our industrial equipment retail, lease and dealer portfolios (hereinafter the “commercial finance business” or “disposal group”) to held-for-sale as all of the following criteria were met: management, having the authority to approve the action, committed to a plan to sell the disposal group; the disposal group was available for immediate sale in its present condition subject only to terms that are usual and customary; we located a buyer; the sale of the disposal group was determined to be probable, and transfer of the disposal group was expected to qualify for recognition as a completed sale within one year; the disposal group was actively marketed for sale at a price that was reasonable in relation to its current fair value; and actions required to complete the plan indicate that it was unlikely significant changes to the plan would be made or that the plan would be withdrawn.

We initially measure a long-lived asset or disposal group that is classified as held-for-sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group, less any costs to sell, each reporting period it remains classified as held-for-sale. We report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held-for-sale.

Cash flows associated with the assets held-for-sale are reflected as investing activities within the Consolidated Statement of Cash Flows. See Note 8 – Other Assets and Other Liabilities of the Notes to Consolidated Financial Statements for additional detail.

New Accounting Guidance

In May 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the recognition of revenue from contracts with customers. This comprehensive standard will supersede virtually all existing revenue recognition guidance. This standard applies to all contracts with customers except leases, insurance contracts, financial instruments, guarantees, and certain nonmonetary exchanges. In August 2015, the FASB issued a one-year deferral of the effective date, with early adoption as of the original effective date permitted. We expect to adopt the new guidance on its deferred effective date, which is April 1, 2018 for TMCC. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.

In February 2015, the FASB issued new guidance that amends the analysis a reporting entity must perform to determine whether it should consolidate certain legal entities. This accounting guidance is effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In April 2015, the FASB issued new guidance that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. In August 2015, the FASB issued an additional update which clarifies that debt issuance costs for line of credit agreements may continue to be deferred and amortized. This accounting guidance will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In April 2015, the FASB issued new guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. While similar guidance exists under current US GAAP for cloud service providers, this update provides explicit guidance for a customer's accounting. This accounting guidance will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In May 2015, the FASB issued new guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. This accounting guidance is limited to footnote disclosure and will be effective for us on April 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In May 2015, the FASB issued new guidance that requires additional disclosures related to short-duration insurance contracts. This accounting guidance will be effective for us for the annual period beginning April 1, 2016 and for interim periods within annual periods beginning April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.

Recently Adopted Accounting Guidance

In April 2015, new FASB accounting guidance became effective that amends the requirements for the reporting of discontinued operations and requires certain additional disclosures. Under the new guidance, only disposals that represent a strategic shift and that have (or will have) a major effect on an entity’s operations and financial results should be presented as discontinued operations. This guidance was adopted by us in August 2015 when we reclassified certain assets and liabilities related to our commercial finance business as held-for-sale. As the sale of our commercial finance business did not represent a strategic shift that will have a major effect on our operations and financial results, it did not meet the criteria to be presented as a discontinued operation. Our adoption of this guidance did not have a material impact on our consolidated financial statements.
