Stock options are gaining popularity among startups in Japan.

These stock option plans offer employees the right to buy company shares at a predetermined price, which aligns the employee’s own interests with the company’s objectives. This helps foster a deeper commitment to their work.

Offering employee stock option plans (ESOP) for private companies isn't new. It just hasn’t been as ubiquitous as in places like SIlicon Valley due to certain caveats.

Until recent years, many employee stock option plans offered by Japanese companies were pretty limited. They had "termination clauses" and "vested schedules". These limitations would only unlock the benefits gradually, and usually meant employees would lose access to their stock options if they left the company.

This practice nullified some of the advantages that came with having stock options, but thanks to recent government initiatives, more and more companies in Japan have been introducing stock option programs with more clear benefits to their employees.

In this post, I’ll introduce the top startups in Japan that offer great employee stock option plans.

Let’s jump right in.


Established in 2013, Mercari is one of the biggest success stories in Japan. The company is best known for the app Mercari, which is Japan’s largest customer-to-customer marketplace.

The app allows users to buy and sell previously owned items with great ease, which includes everything from clothes to consumer electronics.

Since its conception, Mercari has been on a mission to become a global tech giant and currently has a group of subsidiaries under its corporate umbrella. In its endeavors to do so, the company has been making top-notch efforts to make its employees a true part of the company with its employee stock option program.

In addition to this, it also offers fund matching, which allows employees to purchase even more stocks equal to the amount of funds matched by the company.


Established in 2017 as a part of Mercari’s group of companies, the FinTech startup Merpay offers a payment platform for both businesses and individuals.

Merpay is essentially Mercari’s own online payment system, created as the company’s cashless payment service.

Since then, the system has become widespread in Japan, and the company currently offers services such as an e-wallet for electronic payment identifications and online payment.

As part of Mercari, Merpay also offers an employee stock option program as part of its incentive system, which allows employees to purchase additional stock from the company with fund matching.
