HiJoJo Partners was founded by industry insiders with backgrounds in trading, investment banking, systems administration, and regulatory/compliance.


Norifumi Akiyama
Executive Officer of Mizuho Securities Co., Ltd.

“Mizuho Securities aims to expand the fund-business globally through investing our own money and to provide high-quality services by offering more guidance on top of distributing information and sophisticated analysis.

We have already conducted various collaborations with HiJoJo Partners in the past. Through this Series A investment, we would like to further deepen our cooperation as a partner, seeking new financial possibilities such as in the FinTech industry and strive to develop the financial market. ”Excerpt from our press release "Completion of Series A Funding"

Hiroyuki Shinshiba
President of Okasan Securities Group Inc.

“The Okasan Securities Group owns several securities, such as face-to-face, online, and asset management, with a purpose to respond to the various needs of each customer in detail and contribute to their investments.

With that perspective, we believe HiJoJo Partners is a pioneer in offering new options to invest in middle and late-stage companies from overseas and play a great role by offering investment opportunities that are difficult for investors in Japan to obtain.

The environment for investing in unicorn companies has recently changed drastically from the effect of Coronavirus. However, especially in times like this where the future is very unpredictable, it is important to closely keep an eye out on this next era.

With these unique challenges that companies may face with the ‘new normal’ after the pandemic, we hope to further contribute to providing services and products to even more investors. ”Excerpt from our press release "Completion of Series A Funding"

Oki Matsumoto
Chairman and CEO of Monex Group, Inc.

“Since our founding, we have been the first internet securities company to undertake independent lead management of an IPO, start a stock lending service, as well as overseas stocks to enhance our products, services, and information. In addition to enhancing our services, we have been fully involved in improving the investment activity environment for individual investors, such as playing an important role in introducing the unit share system.

With HiJoJo Partners' main focus on unicorn companies, we believe that this company is one of the few players who can access unlisted stocks, which are of great interest to investors. Their corporate philosophy matches our spirit of this challenge, and we have great confidence that we can open up new markets together. ”Excerpt from our press release "Completion of Series A Funding"
