Planning a corporate reception for 20 guests in Osaka? Most venues create a "capacity gap"—leaving you to pay for empty seats or sacrifice privacy. Discover the true end-to-end costs and hidden fees of ATC LOUNGE versus Osaka's luxury hotel giants.
When you see "¥15,000 per person" on a hotel website, that's rarely your final cost. Japan's pricing structure follows a specific sequence that most international planners find surprising: Base Rate → + Service Charge (10-15%) → + Consumption Tax (10% applied after service charge).
According to japan-meetings.com's 2025 venue pricing benchmarks, this compounding effect means a quoted ¥200,000 base rental actually becomes ¥253,000.
Research by ATC Hall's venue analysis reveals a systematic market failure. Most restaurants cap private dining at 12 seats, while luxury ballrooms demand 40-50 guests minimum. This creates an expensive "small group penalty" where you pay for empty seats.
Purpose-built for the 12-20 guest sweet spot, offering total transparency.
While hotels offer prestige, their business models are designed for volume. For groups of 20, you often end up paying a "phantom guest" tax to meet minimum ballroom requirements.
Best for Convenience
All-inclusive packages start at ¥11,000/person (¥220,000 total for 20). Simpler logistics but zero catering flexibility and 2-hour limits.
High Penalty Risk
Packages from ¥16,000/person require 40 guests minimum. For 20 guests, you pay for 40—effectively ¥32,000/person.

Private rooms start at ¥25,500/person for dinner (¥510,000 total for 20). Unmatched brand recognition but at 2-3x the cost.

Beyond base rental, expect 10-15% service charges, 10% consumption tax (applied after service), overtime fees, and setup charges. According to JNTO MICE statistics, total costs can be 30-40% higher than initial quotes.
Yes, ATC LOUNGE is "catering-friendly" with a full commercial kitchen (IH stoves, service counter), allowing external caterers or Chef's Table experiences. This distinguishes it from hotels' mandatory in-house models.
