Plimes Gokuri on Woman's Neck

Japan's startups regularly spearhead innovations that provide solutions for aging populations. This is clearly shown in Plimes' first product, GOKURI, an AI product that monitors the swallowing capacity of elderly individuals.

This AI-powered point of care product comes as a wearable device around the neck, providing clinicians and medical institutions and those in the health care industry with the ability to monitor against choke risks in stroke patients and the elderly.

This device, and many others like it, show Japan's deep understanding of the needs that elderly individuals face and the innovative solutions that Japanese startups are taking to tackle these issues.

Vanguard Industries

Vanguard Industries

Vanguard Industries is a Tokyo startup that specializes in concept, solution, product, and experience design. Their first product, the MOFLIN, raised over $600,000 through a Kickstarter campaign and netted them an honoree placement in the 2021 CES Innovation Awards, which acknowledges outstanding design and engineering in consumer technology products within the startup scene.

The MOFLIN is an AI pet that exhibits emotional learning patterns that provide a real-life pet experience. Its expressions will change as it is given care. Masahiko Yamanaka, Vanguard Industries' CEO, proposes that taking care of a MOFLIN could help prevent the onset of dementia and could be used in psychotherapy for elderly patients. Additionally, families that cannot take care of a real-live pet can still teach children essential aspects of sensitivity and caring for a pet through MOFLIN. Visit their JETRO CES page here

Tokyo Supercars

Tokyo Supercars

Tokyo Supercars is a luxury car-sharing company that provides rental opportunities, day tours, racing experiences, and more in the Greater Tokyo Area, delivering a service that's the first of its kind in Japan. 

The business provides a platform, enabling owners of luxury supercars to share their rides with car enthusiasts, allowing users to experience cruising through Tokyo at night in a Porsche, Ferrari, Aston Martin, or another vehicle from their high-end lineup. Founded by a small team with a capital of ¥51,000,000 and a passion for supercars, Tokyo Supercars' services include car-sharing, rental, corporate incentives, and partnerships.

Offering up new experiences in the Tokyo area helps to further international interest and domestic tourism and provides an experience-based source of entertainment unassociated with the food and dining industry. 


Smart HR

As addressed in a previous article, the number of procedures required to start and run a business in Japan are lengthy and notorious. SmartHR solves a lot of that. They provide software that companies can subscribe to, streamlining various human resources tasks, such as employment contracts, new-hire onboarding procedures, year-end adjustments, online payslips, and various of Japan's many labor procedures. 

Established in 2013, SmartHR won several awards from various startup conventions right from the start, winning startup funding rounds and then series B funding of  ¥1.5 billion ($13.3 million) in 2018. Today, this is one of the top Japanese startups and is worth ¥490 million, and Rakuten and Mercari are among SmartHR's strategic partners.

SmartHR software allows middle managers and staff to concentrate on their business's primary purpose, rather than wasting time on the mind-numbing amount of paperwork required to run a business in Japan.

Allbirds Japan

Allbirds Japan

The “world's most comfortable shoe” company opened its first store in Tokyo on January 10, 2020. After seeing vast success online and with an A-list lineup of individuals who wear Allbirds footwear, Allbirds chose Harajuku for their first store location in Japan. The company uses merino wool and eucalyptus fibers for the shoe body. The sole is made from sugar cane, the insole is made from castor oil, and the shoelaces are made from recycled PET bottles.

In an interview with Forbes Japan, co-founder Joey Zwillinger stated that as a startup company, he had always wanted to open his store in Harajuku, where people gather who have a startup spirit and are sensitive to fashion trends. 

Allbirds sneakers' use of environmentally friendly materials is one of its most significant growth and attraction components as climate change awareness and activism spread worldwide. Shop location in Harajuku also places Allbirds squarely within the sights of its target demographic.



A different take on the average babysitting agency, CareFinder is a Tokyo startup that aims to build and support connections between families and babysitters. Caregivers are selected through rigorous screening and interviews and preferred networks, such as ID checks (licenses and passports) and work visa checks. Many sitters are from various countries and are bilingual in English, Japanese, and other languages.

Founded in 2013 by Megumi Moss, a former Sony employee, CareFinder stands apart by welcoming international babysitters with a wide range of skills, giving special attention to bilingual caregivers, so that children can become fluent in English and Japanese when language-acquisition peaks. 

This is one of the fastest-growing babysitting communities in Tokyo, providing parents with the ability to search for a sitter with a particular skill set and then negotiate directly on fees and hours. First gaining popularity among the expat community, it has since grown to become popular for Japanese working mothers and parents who are looking to provide their children with an at-home English environment. 



Mymizu won 2020's Good Life Award, a Minister of Environment Prize, and it's simple to see why. The Good Life Award celebrates the top eco-friendly initiatives in Japan, which are tackling large-scale environmental problems. Mymizu does that through its app that guides you to the nearest water fountain or eco-friendly cafe that offers free refills.

The mission? Eliminating the use of plastic bottles—and promoting personal bottle use by pointing you to free refill spots so you can refill your bottle on the go. Initial funding was completed within the first 48 hours of the project on Kickstarter. Mymizu has since received funding from several sources, including the iF World Design Award “Social Impact Prize 2019” that came with a monetary prize.

Apps like this are needed to combat plastic consumption, which is likely to peak with incoming spectators, athletes, and related individuals. 

In closing

The Japanese startup ecosystem has many delightful entries, from startups that focus on business development to those that provide an online platform that boosts remote work capabilities.

These startups all contribute toward Japan's growing startup economy and have created products that feel timely, not just for Japan's economic growth, but also for developing countries and markets worldwide.
