| Risk Lose Money [Member] | |||||||||
| Prospectus [Line Items] | |||||||||
| Risk [Text Block] | Investing in any exchange-traded fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund’s portfolio. An investment in the Fund may not be appropriate for all investors. | ||||||||
| Risk Nondiversified Status [Member] | |||||||||
| Prospectus [Line Items] | |||||||||
| Risk [Text Block] | Nondiversification risk — A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer. Because a nondiversified fund may invest its assets in fewer issuers, the value of its shares may increase or decrease more rapidly than if it were fully diversified.
|
||||||||
| Market risk_ | |||||||||
| Prospectus [Line Items] | |||||||||
| Risk [Text Block] | Market risk — The risk that all or a majority of the securities in a certain market — such as the stock or bond market — will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.
|
||||||||
| Japan investment risk | |||||||||
| Prospectus [Line Items] | |||||||||
| Risk [Text Block] | Japan investment risk — The Fund’s performance is expected to be closely tied to social, political, and economic conditions within Japan and to be more volatile than the performance of more geographically diversified funds. Japan’s economic growth is dependent on international trade, and slowdowns in the economies of key trading partners could have a negative impact on the Japanese economy. Japan also lacks many natural resources, and, as such, price increases, volatility or shortages in the commodities markets and currency fluctuations could adversely affect Japan’s economy. Japan’s labor market is adapting to an aging workforce and declining population, and such demographic shifts may hinder Japan’s economic competitiveness in the future.

| Model risk | |||||||||
| Prospectus [Line Items] | |||||||||
| Risk [Text Block] | Model risk — Any investment model may experience periods of outperformance as well as periods of underperformance. Like all quantitative analysis, the investment models utilized by the Fund carry a risk that the mathematical models used might be based on one or more incorrect assumptions. Rapidly changing and unforeseen market dynamics could, in some cases, lead to a decrease in short term effectiveness of the Fund’s mathematical models. No assurance can be given that the Fund will be successful under all or any market conditions.
