TradeWorks Expands 'Tsumitate Kabu' Service to Include U.S. Stocks

TradeWorks Expands 'Tsumitate Kabu' with U.S. Stock Investment Features

In an exciting development, TradeWorks, a company known for its innovative solutions in finance through AI, security technology, and blockchain, has announced the expansion of its 'Tsumitate Kabu' service to include U.S. stock investment capabilities. The addition of this feature comes shortly after the service's initial launch for Japanese stocks, set for December 2025. This new functionality allows investors at DMM.com Securities to invest in both Japanese and U.S. stocks starting from just 1,000 yen, all from the same platform. The structure of this cumulative investment offers a streamlined approach to investing in individual stock options across both markets, marking it as a pioneering initiative within the online brokerage sector.

Background of the Service Development

The venture began with the first phase on December 2025, when the service was launched for domestic stocks, including ETFs. It catered to various NISA (Nippon Individual Savings Account) investment frameworks, making it easy for novice investors to make small, manageable investments.

With the launch of the U.S. stock investment feature in June 2026, the service will facilitate the investment process even further, enabling users to select from a wide range of stocks while enjoying the convenience of a single investment platform.

Key Features of 'Tsumitate Kabu'

'Tsumitate Kabu' is designed with the novice investor in mind, providing valuable features that enhance user experience:
1. Low Minimum Investment: Investors can start with as little as 1,000 yen per stock, making stock investing more accessible.
2. NISA Compatibility: The service supports both NISA's cumulative investment and growth investment frameworks, which allow users to enjoy tax-free benefits on profits and dividends.
3. Automated Purchasing: Once users set up their stock selections and buying cycles, automatic purchases will continue, facilitating ongoing asset formation without additional management.
4. Flexible Purchase Cycles: Users can customize their investment frequency to daily, weekly, or monthly intervals, aligning with their individual lifestyle needs.

The service stands out by offering coverage of all ETFs under the NISA cumulative investment framework. Since ETFs are traded on exchanges, they offer high transparency and lower management costs compared to traditional mutual funds. With the automatic reinvestment of asset distributions, investors can expect easier long-term, diversified asset building.

Growing Interest in Long-Term Investment

Recent trends show a rising interest in long-term and cumulative investments, particularly among younger individuals, driven by NISA’s evolving guidelines. The U.S. stock market, known for its historical highs, has seen increased interest in individual stock investments. Technological advancements and the emergence of generative AI have made information gathering and analysis much more accessible, allowing investors to choose individual growth stocks they believe in without the need to solely rely on diversified investments or indexes.

TradeWorks anticipates that with these emerging trends, cumulative stock investments will become a popular option for long-term asset growth. Following the release of the Japanese stock investment functionality in December 2025, numerous requests for U.S. stock investments have been received. In response, TradeWorks has worked diligently to incorporate features that adapt to U.S. stock transaction timelines and integrate currency exchange rates among other enhancements.

Future Directions

TradeWorks remains committed to helping brokerage firms diversify their service offerings. Looking ahead, the firm plans to further expand its range of supported stocks, enhance user interface and experience for investors, and automate investment plans to solidify its role as a cornerstone for long-term asset formation.
