Japan's corporate culture has a long tradition of treating compensation as confidential. Salaries are not discussed between colleagues. Bonus amounts are not shared. This norm extends naturally to equity, where option grant sizes and vesting status are kept tightly private, sometimes to the point where employees are not sure whether their grants are actually valid.
In large traditional companies, this confidentiality norm mostly works because most employees do not hold equity at all. But at a startup where equity is a meaningful component of every team member's total compensation, maintaining the same level of opacity creates a set of problems that are specific to the startup context.
What opacity around equity actually costs
When employees do not clearly understand their equity position, several things happen. First, they cannot make rational career decisions that incorporate equity value. If an employee is weighing an offer from another company, they need to understand what they would be giving up. A vague sense that they have "some options" is not useful for that calculation. If they cannot get clear answers, they will discount the equity to near zero and make their decision primarily on salary.
Second, if employees suspect but cannot confirm that peers received different grant sizes, rumor fills the information vacuum. The resulting conversations are usually less accurate and more corrosive than the truth would have been. A company where people are whispering about who got how much equity, without any framework for why differences exist, has an equity culture problem that is not solved by confidentiality.
Third, employees who do not understand their vesting timeline cannot be motivated by the prospect of vesting milestones. The monthly vest is a retention tool. But it only works as a motivational factor if the employee knows it is happening, knows what it is worth at current valuation, and cares about it. An employee who received an offer letter with an option grant, signed it, and has never received any subsequent communication about their vesting status is effectively not being managed with equity as a retention tool at all.
Transparency does not mean publishing everyone's grant size
It is worth separating two things that often get conflated: individual grant size confidentiality versus policy and framework transparency. You can maintain confidentiality about what any specific person received while being completely transparent about the framework that determines grants: what the criteria are, how roles and seniority factor into the calculation, what the vesting terms are for different hire types, and what the current exercise price is.
When someone joins the company and receives an equity offer, they should be able to understand where that offer sits within a coherent framework. "Engineers at your level of seniority joining at this stage typically receive grants in the 0.3 to 0.6 percent range, based on our current fully diluted share count, with our standard four-year vesting schedule" is more useful and more honest than handing someone a number with no context.
A framework-level transparency also makes the offer conversation easier. When a candidate asks "is this a fair offer?" you can give them a meaningful answer, not because you are disclosing what other specific people received, but because you can explain the logic behind the number.
Regular equity updates build trust over time
Many startups issue option grants and then never communicate with option holders again until an exercise event or an acquisition. The option holder is left to remember their own grant terms, calculate their own vesting status, and estimate the current value of their options with no updated information from the company.
A better practice is to communicate with option holders at least annually. The communication does not need to be elaborate: a summary of their current vested position, their unvested position, any partial exercises they have made, and the current total share count. It can be as simple as a quarterly or annual statement that each holder receives through a secure portal.
This communication serves several purposes. It reminds employees that equity is a real part of their compensation, not a theoretical promise. It prevents the situation where someone leaves the company and realizes they had no idea what was vested. And it signals organizational competence: a company that can produce accurate, timely equity statements for its option holders is a company that has its equity records in order.
The retention data on equity transparency
We do not have large-scale research specifically on Japanese startups and equity transparency. But the pattern we observe in the companies we work with is consistent with what the broader international research suggests: employees who clearly understand their equity position, who receive regular updates about their vesting status, and who trust that the grants they received were set fairly, stay longer.
This is not surprising. Uncertainty about equity value is a form of cognitive discomfort. When someone does not know whether their equity is worth something, cannot trust the vesting records, and has no framework for understanding whether they were treated fairly relative to their peers, the rational response is to resolve that uncertainty by leaving and taking a cash-compensation-heavy job elsewhere. Clarity about equity value, even when the current valuation suggests the options are not worth much yet, is better than uncertainty.
Starting with the right infrastructure
Equity culture is not something you build after the fact by sending better emails. It starts with having accurate records. You cannot tell your employees what their current vested position is if your own records are not current and reliable. You cannot communicate the current exercise price in a way that employees can trust if the underlying FMV determination process is informal or undocumented.
The companies that have the healthiest equity cultures are the ones that set up structured equity management from the beginning: accurate records, documented grant terms, regular maintenance. When the records are right, transparency is cheap. When they are not, transparency becomes a liability because what you would be revealing is disorder.
Building a fair equity culture at a Japanese tech company is genuinely possible despite the prevailing confidentiality norms. It requires choosing to be more transparent about frameworks than custom dictates, and having the organizational discipline to maintain records that make transparency credible. Both of those things are choices, and the companies that make them tend to find that the return on that investment, in retention and in trust, is real.
