Mom Investor Choroko, Who Built ¥100 Million in Assets During Maternity Leave, Speaks at One-Day Financial Event Where 36 Women Learn Asset Formation

Manekatsu by FANTAS, a women-focused financial seminar operated by FANTAS technology Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Kohei Kokushi), held a collaborative event titled 'One-Day Lesson: Learn Stock and Real Estate Investment!' on June 28, 2026, at the company’s office. The event commemorated the 10th anniversary of 'Kinyu Joshi,' a community for women unfamiliar with finance, and the publication of a book by mom investor Choroko.

The event welcomed 36 women, primarily in their 20s to 40s. Participants learned about asset formation, including stock investment and financial mindset, while reflecting on their ideal future life plans.

Guest: Mom Investor Choroko

A part-time investor and mother of two, Choroko began stock investing in 2011 with ¥2.4 million. She started serious investing in 2019, reached ¥100 million in assets by 2021, and surpassed ¥300 million by 2025. She has gained attention for her authentic posts on X about her investment journey and insights.

Responding to Rising Demand: Creating a Space to Envision a Personalized Future

In recent years, rising prices and economic uncertainty have increased interest in asset formation across all age groups and life stages. However, many women still feel unsure about where to begin or lack confidence in financial knowledge.

Manekatsu by FANTAS provides a supportive environment where every woman can expand her life choices and build financial literacy to design her own future. The platform offers diverse learning opportunities on asset management.

For this event, Choroko was invited as a guest speaker—a mom investor who has pursued asset formation while navigating life changes like parenting and work. She shared her personal experiences, including how she approaches investing and maintains consistency.

Learning from Experience: How to Approach Asset Formation

The event featured a talk session by Choroko.

She began stock investing in 2011 with ¥2.4 million, gradually building experience through trial and error. During the session, she shared her investment philosophy, decision-making criteria, and daily methods for gathering financial information.

She also discussed how she managed investing during maternity leave and what she learned from past failures, offering practical asset-building strategies applicable to everyday life.

Following this, Manekatsu by FANTAS staff member Arata Niimi explained long-term asset formation strategies and the characteristics and uses of various financial products, including stocks, insurance, and real estate.

Participants compared different financial instruments and considered which options best aligned with their personal life plans and values.

Lunch Networking: Sharing Perspectives on Asset Formation

During lunch, participants discussed the topic: "How would you invest ¥1 million?"

Responses included:

"I’d start with a NISA account."

"I want to combine index funds and individual stocks."

"I’d like to learn more about high-dividend stocks."

This exchange created an open forum where beginners and experienced investors alike shared diverse perspectives on wealth building.

Later in the event, a casual chat session and autograph signing were held. These interactions helped build a community where participants can comfortably learn about finance together.

Participant Feedback

"Choroko’s philosophy of ‘applying what I learn immediately’ really resonated with me. I want to set one small goal each day and take action."

"I realized I want to learn more about asset formation and taxes."

"It was inspiring to connect with women my age who are also interested in investing."
