Coworking Space Mangrove

A booth-based coworking space in central Naha, on the second floor of the OCT Forest Building operated by Okinawa Cellular Telephone (KDDI Group). The concept is unusual for Japan. Nearly all seats are semi-private booths with high partitions rather than open-plan desks. Reviewers repeatedly cite this layout as the reason they concentrate better here than at other spaces.

There are 12 single-person booths and 2 two-person booths, plus 4 single-person phone booths (Cubes) and a two-person Cube. Nine of the single-person booths have external monitors. All booths have power outlets. Reservations are required in advance. You book online and enter via a QR code emailed to you. Drop-in is not truly walk-in. You need to pre-book. Hours for non-members areweekdays 9:00 to 18:00 only. Monthly members access from 8:30 to 20:00. The space is closed on weekends and public holidays for all plans.

Wi-Fi is backed by the KDDI Group's network. Reviewers describe it as fast and consistently reliable, with multiple people confirming it handles video calls without issue. One reviewer specifically called out that the internet speed is "impeccable" given the operator's telecoms background. There is also a library, a multifunction printer, and aroma therapy in the space.

A free drink bar is included with every plan. Coffee, tea, and water are available. One reviewer also mentions complimentary glucose snacks. No food is served on-site and there is no kitchen. Dietary information for the drink bar beyond coffee and tea is not confirmed in available data. A cheap set-meal restaurant is nearby according to at least one reviewer.

Pricing (2026 rates). Drop-in is¥990/hour, a full day is ¥2,200. Multi-day passes run ¥5,280 for 3 days and ¥8,800 for 5 days. Monthly plans start from ¥9,900 for a 40-hour share plan. Individual flat-rate monthly membership is ¥24,200. Meeting rooms and phone booths cost extra and require advance booking.

Staff are the other standout. Virtually every review mentions them. Helpful, kind, fluent enough to assist international visitors, and willing to explain the QR system and booking flow in detail on a first visit. One visitor was accommodated before 9 AM to log in for work.
