Opportunities to Socialize
ZEALS provide a club activity allowance, a “shuffle lunch” allowance for having cross-departmental lunches, and ZEALS Bar, free flowing beer party.

Japanese Language Policy
At ZEALS, the product and technology team members primarily speak English (dev-related discussions happen in English on Github or Slack). There might be occasional discussions in Japanese, but most Slack messages are in English (or both languages).

As for meetings, all dev-related discussions take place in English. Given the above, Japanese skills are not required for most positions in the Product & Technology departments. However, one unique aspect of ZEALS’ culture is the desire to increase teamwork and engage with each other, which is why many Japanese members are working on their English skills while many non-Japanese members also work to improve their Japanese skills.

In order to build a truly global team, ZEALS has many multilingual members that proactively support the rest of the team to ensure smooth communications.

Even outside of the Product & Technology departments, all important company-wide announcements are made in both English and Japanese. For example, hiring announcements, new product launches etc. are generally announced in both Japanese and English.

Also, simultaneous interpretation for presentations at large meetings and events is provided to ensure that everyone gets the information they need.
