ヒロマラボ
A drop-in coworking space on the 17th floor of Hirogin's Hiroshima building, with unobstructed views over the city and the Chugoku mountains beyond. Operated by ATOMica in partnership with Hiroshima Bank Holdings and Hiroshima Venture Capital, the space is professionally run and community-oriented. The concept is simple. Bring motivated people together in one place and let connections form. One reviewer who worked at coworking spaces across Tokyo, Kyoto, and Hiroshima called it the best of the three.
Drop-in use costs ¥1,100 per day, no reservation needed. You can walk in, check in at the front desk, and get to work. Monthly plans range from ¥8,800 for 10 days per month up to ¥35,200 for 320 hours. Hourly members can share their plan across multiple users. Members get extended access from 7:30 to 21:00 every weekday. Non-members and drop-ins are limited to 9:30 to 18:30, with a last entry at 18:00. The space is closed on weekends and public holidays. That is the main limitation to know before planning your week around it.
The workspace is open-plan with varied seating across a free-address floor, a Sky Lobby, counter seats, sofa areas, and recessed group tables. High ceilings and full-length windows create a genuinely open feel. Free drinks are included with every session, courtesy of a bar area with a tea dispenser, fridge, and microwave. Phone booths (tele-booths) are available for calls and video meetings. A color multifunction printer is on-site. Meeting rooms seat 8, 10, or 22 people and are available to both members and drop-ins at hourly rates.
The wifi is fast and reliable. Multiple reviewers specifically came here to escape slow connections elsewhere in the city. Staff are Japanese-speaking but consistently praised for being warm and helpful with non-Japanese visitors. One frequent visitor noted buying a day pass was easy with limited Japanese. A dedicated community team is on-site during all operating hours.
No food is sold on-site. The bar area has free hot drinks and a microwave, so you can bring your own. Dietary options are not confirmed in any available source data. If you have specific dietary requirements, check with the space or bring your own food. Plenty of cafes and restaurants sit within walking distance in the Ginzan-cho and Kamiyacho area.
