Disrupting Industries: Spotlight on PayPay

One startup that has made significant waves in its industry is PayPay, a mobile payment service. PayPay, as reported by the Financial Times, has been instrumental in disrupting the traditional finance sector. The company has been successful in promoting digital payments in a country that has long been cash-dependent, demonstrating that startups can indeed challenge and change longstanding customs and practices. PayPay’s success can be attributed to a combination of strategic marketing, efficient logistical planning, and the application of technology to enhance efficiency. The company has shown how startups can leverage these elements to make a significant impact in their respective industries. 

How PayPay Disrupted Traditional Customs in Japan

PayPay’s disruption of Japan’s traditional cash-based economy provides a fascinating case study on how startups can drive societal changes. According to a Reuters report, PayPay’s user-friendly platform and aggressive marketing campaigns, often offering substantial discounts and rewards, have encouraged Japanese consumers to adopt digital payments. This shift towards digital finance is a significant change in a country where cash has long been king.

International Collaboration and Influence

Japan’s startup ecosystem is increasingly gaining international attention and collaboration, which is enhancing its global influence. The country’s startups are forming partnerships with international corporations, securing funding from foreign investors, and expanding their operations overseas. For instance, PayPay, the fintech startup mentioned earlier, was formed as a joint venture between SoftBank and Yahoo Japan in collaboration with India’s Paytm. This partnership highlights how startups in Japan are leveraging international expertise to disrupt traditional industries.

Progress in Deep Tech Startups

There’s also significant growth in deep tech startups. For instance, Kyoto Fusioneering, a leader in fusion power plant engineering, and Astroscale, focusing on orbital debris removal, have raised substantial funding rounds in recent years. These companies highlight Japan’s competitive edge in advanced technology sectors and their contributions to global technological advancements​

Startups and Society: Impact Beyond Business:

The impact of startups in Japan extends beyond the business realm, influencing various aspects of society. From driving shifts in work culture to solving social issues, startups are playing a crucial role in shaping Japan’s future. The Japanese government has played a crucial role in fostering this ecosystem. The ‘Five-Year Plan‘ announced by the government aims to accelerate startup activities, with goals such as increasing startup investments 10x and creating 100 unicorns by 2028. This plan includes provisions for risk capital, renewing the SBIR (Small Business Innovation Research) program, connecting with global startup ecosystems, providing tax incentives for M&A, and upgrading stock option regulations​.

  1. Changing Work Culture

The startup culture challenges the traditional Japanese work ethic, which often involves long working hours and lifetime employment. Startups often promote a more flexible and diverse work culture, emphasizing work-life balance, creativity, and individual initiative. This shift is not only attracting more young people to join or start their ventures but also influencing established corporations to rethink their work practices.

  1. Addressing Social Issues

Many Japanese startups are also committed to addressing social issues. For example, startups in the healthcare sector are developing innovative solutions to improve medical services and elderly care, which are pressing concerns given Japan’s aging population. Also, environmental startups are creating technologies to combat climate change and promote sustainable living.

  1. Encouraging Female Entrepreneurship

Japan has also seen a rise in female entrepreneurship. While women are still underrepresented in the startup scene, more and more women are launching their businesses and breaking into leadership roles. Organizations such as Women’s Startup Network Japan are providing support and resources to empower female entrepreneurs, contributing to diversity and inclusion in Japan’s startup ecosystem. For Empowering Women (FEW) in Japan is a nonprofit organization that champions the professional and personal growth of women. Through networking opportunities, seminars, meetings, and special events, FEW inspires, educates, and connects globally-minded women. Their significant contributions are aiding the growth of female entrepreneurship and enhancing diversity within Japan’s startup ecosystem.

As the Japanese startup ecosystem matures, characterized by improved access to funding for Japanese startups, a swelling talent pool, and amplified government support for startups in Japan, it fuels a promising outlook. Moreover, the heightened internationalization of Japanese startups is bolstering their competitiveness on a global stage.

This, in turn, stimulates Japanese economic growth and instigates societal transformation. With their innovative solutions and disruptive potential, Japanese startups are reshaping their industries and setting the stage for a more sustainable and innovative future. The impact of these startups is so profound that it’s fair to say Japanese startups are driving societal change.

New Exit Strategies in Startup Systems

The resilience of Japan’s IPO market further underscores the robustness of the ecosystem. In 2023, 49 startups went public, demonstrating a strong rebound from previous years. Notable IPOs include Cover, a next-generation media and metaverse company, which realized an initial market capitalization of over JPY 100 billion (approx. USD 711 million). The growing trend of significant IPOs and M&A deals, such as MUFG’s acquisition of Kanmu, highlights the evolving exit strategies available to Japanese startups.

Additional Case Studies: Astroscale, BitStar, and WealthPark

Further examples of startups disrupting their respective industries in Japan include Astroscale, BitStar, and WealthPark.

Astroscale, an aerospace startup, is addressing the growing issue of space debris. By pioneering solutions for orbital debris removal and on-orbit servicing, Astroscale is not only innovating within its industry but also contributing to the sustainability of space operations, a concern that impacts global security and communication systems.

BitStar, a platform for content creators, is capitalizing on the rise of the gig economy and the increasing value placed on digital content. By providing a platform where creators can monetize their work, BitStar contributes to the evolution of digital economies and labour models.

WealthPark is a real estate management platform that offers tools for property owners and managers to track their assets and operations. By digitizing and streamlining aspects of property management, WealthPark is leading the PropTech industry in Japan and transforming how real estate businesses operate.

In addition to these, the rise of deep tech in Japan is particularly noteworthy. University spin-out startups have increased from 131 in 2014 to 1,335 in 2022, nearly a tenfold increase. Government subsidies and deep tech-focused venture capital funds, such as those affiliated with leading universities, have been instrumental in supporting these startups. Examples include Ookuma Diamond Device, which manufactures diamond semiconductors, and Logomix, a synthetic biology platform leveraging advanced genome editing technology

What government benefits are startup companies in Japan receiving?

Japan’s government has taken proactive steps to foster startup growth through a range of incentives, including tax deductions, grants, and additional benefits intended to alleviate the financial burden on new businesses. Among these are several corporate tax incentives, specifically those aimed at small and medium-sized enterprises (SMEs). These incentives include a reduced corporate tax rate and tax credits for research and development endeavors.

Every prefecture in Japan may also provide various tax incentives to attract businesses. Comprehensive information about these benefits can be found on the JETRO website. For startups seeking more precise insights into these benefits and how to navigate them, The article Ultimate Guide to an Accountant in Japan can be a valuable resource for understanding the role of accountants in managing these benefits. The article on Tax Reduction: Bad Debts as Accounting Loss gives insights into how bad debts can be used as accounting losses, which can further reduce the tax burden. Additionally, the post on Short-term Prepaid Expenses in Japan provides valuable insights into managing short-term prepaid expenses, another important aspect of financial management for startups in Japan.

The Scaling Your Company website, coupled with the government’s supportive measures, provides a robust environment for startups to grow and thrive in Japan.

Foreigners Owning Businesses in Japan

Japan is an open market that encourages foreign investment, permitting foreigners to own businesses within the country. The national government is actively enhancing the global competitiveness of Japanese startups by internationalizing the startup ecosystem. The procedure of initiating a business as a foreigner in Japan is detailed in the resource written by Tyson Batino. Mercari, for example, was co-founded by Tommy Tomishima, a Japanese entrepreneur who was born and raised in the United States. Mercari has become one of Japan’s unicorn startups with Tomishima relocating back to the United States to expand the operations of Mercari, exemplifying the international reach of Japanese startups. To attract foreign talent, the Japanese government has relaxed visa restrictions and introduced programs tailored for foreign entrepreneurs. In 2018, the “Startup Visa,” a subset of the Business Manager Visa category, was introduced. This visa allows foreign entrepreneurs to stay in Japan for a year to establish their business. This influx of foreign talent not only infuses the Japanese startup scene with new skills and perspectives but also aids in building a global network.
