Accounting Policies [Abstract]
Summary of Significant Accounting Policies	The accompanying unaudited interim consolidated financial statements and related notes should be read in conjunction with the audited Consolidated Financial Statements of Johnson & Johnson and its subsidiaries (the Company) and related notes as contained in the Company’s Annual Report on Form 10-K for the fiscal year ended January 1, 2017. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. New Accounting Standards Adopted in Quarter Ending April 2, 2017 During the fiscal first quarter of 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2016-07 Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amendments in the update eliminate the requirement that when an investment qualifies for the use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step by step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the application of the equity method. The adoption of this standard did not have a material impact on the presentation of the Company's consolidated financial statements. During the fiscal second quarter of 2015, the FASB issued Accounting Standards Update 2015-11: Simplifying the Measurement of Inventory. This update requires inventory to be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This update is effective for the Company for all annual and interim periods beginning after December 15, 2016. The amendments in this update should be applied prospectively. This update did not have any material impact on the Company’s consolidated financial statements. Recently Issued Accounting Standards Not Adopted as of April 2, 2017 During the fiscal first quarter of 2017, the FASB issued Accounting Standards Update 2017-07: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This update requires that an employer disaggregate the service cost component from the other components of net periodic benefit cost (“NPBC”). In addition, only the service cost component will be eligible for capitalization. This update is effective for the Company for all annual and interim periods beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The Company will adopt this new standard in 2018. The amendments in this Update should be applied retrospectively for the presentation of the service cost component and the other components of NPBC in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of NPBC in assets. The Company is assessing the retroactive restatement methodology and impact to the individual line items on Consolidated Statement of Earnings. The Company does not expect there to be a material impact to net earnings. During the fiscal first quarter of 2017, the FASB issued Accounting Standard Update 2017-05: Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets. This update clarifies the scope of asset derecognition guidance, adds guidance for partial sales of nonfinancial assets and clarifies recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. This update will be effective for the Company for its annual and interim reporting periods beginning after December 15, 2017, the same time as the amendments in Update 2014-09 Revenue from Contracts with Customers. This update allows the Company to choose either a full retrospective method or modified retrospective method upon adoption. The Company is currently assessing the impact of the future adoption of this standard on its financial statements. During the fiscal first quarter of 2017, the FASB issued Accounting Standard Update 2017-04: Simplifying the Test for Goodwill Impairment. This update simplifies how an entity is required to test goodwill for impairment. A goodwill impairment will now be measured by the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This update will be effective for the Company for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. This update should be applied prospectively. The Company is currently assessing the impact of the future adoption of this standard on its financial statements. During the fiscal first quarter of 2017, the FASB issued Accounting Standard Update 2017-01: Clarifying the Definition of a Business. This update narrows the definition of a business by providing a screen to determine when an integrated set of assets and activities is not a business. The screen specifies that an integrated set of assets and activities is not a business if substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single or a group of similar identifiable assets. This update will be effective for the Company for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. This update should be applied prospectively. The Company is currently assessing the impact of the future adoption of this standard on its financial statements. During the fiscal fourth quarter of 2016, the FASB issued Accounting Standards Update 2016-16 Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. This update removes the current exception in US GAAP prohibiting entities from recognizing current and deferred income tax expenses or benefits related to transfer of assets, other than inventory, within the consolidated entity. The current exception to defer the recognition of any tax impact on the transfer of inventory within the consolidated entity until it is sold to a third party remains unaffected. The amendments in this update are effective for public entities for annual reporting periods beginning after December 15, 2017. Early adoption is permitted and should be in the first interim period if an entity issues interim financial statements. The Company is currently assessing the impact of the future adoption of this standard on its consolidated financial statements. During the fiscal third quarter of 2016, the FASB issued Accounting Standards Update 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This update addresses whether to present certain specific cash flow items as operating, investing or financing activities. The amendments in this update are effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. The Company is currently assessing the impact of the future adoption of this standard on its consolidated Statements of Cash Flows. During the fiscal first quarter of 2016, the FASB issued Accounting Standards Update 2016-02 Leases (Topic 842). This update requires the recognition of lease assets and lease liabilities on the balance sheet for all lease obligations and disclosing key information about leasing arrangements. This update requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under current generally accepted accounting principles. This update will be effective for the Company for all annual and interim periods beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. The update is required to be adopted using a modified retrospective approach. The Company anticipates that most of its operating leases will result in the recognition of additional assets and the corresponding liabilities on its Consolidated Balance Sheets, however does not expect to have a material impact on the financial position. The actual impact will depend on the Company's lease portfolio at the time of adoption. The Company continues to assess all implications of the standard and related financial disclosures. During the fiscal first quarter of 2016, the FASB issued Accounting Standards Update 2016-01 Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update supersede the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and require equity securities to be measured at fair value with changes in the fair value recognized through net income. The standard amends financial reporting by providing relevant information about an entity’s equity investments and reducing the number of items that are recognized in other comprehensive income. This update will be effective for the Company for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The Company is unable to estimate the impact of the future adoption of this standard on its financial statements as it will depend on the equity investments as of the adoption date. During the fiscal second quarter of 2014, the FASB issued Accounting Standards Update 2014-09: Revenue from Contracts with Customers, which, along with amendments issued in 2015 and 2016, will replace substantially all current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. Early adoption of this standard is permitted but not before the original effective date for all annual periods and interim reporting periods beginning after December 15, 2017. The guidance permits two methods of adoption: full retrospective method (retrospective application to each prior reporting period presented) or modified retrospective method (retrospective application with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures). While the Company continues to evaluate the effect of the standard, preliminarily, it does not anticipate a material impact on its financial statements. To complete the assessment of the impact of the standard to the financial statements, the Company continues to assess all implications of the standard, method of adoption and related financial disclosures. Additionally, the Company continues to monitor modifications, clarifications and interpretations issued by the FASB that may affect current conclusions.

The accompanying unaudited interim consolidated financial statements and related notes should be read in conjunction with the audited Consolidated Financial Statements of Johnson & Johnson and its subsidiaries (the Company) and related notes as contained in the Company’s Annual Report on Form 10-K for the fiscal year ended January 1, 2017. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented.
