Yokohama Sanbo Hall Marineria

While Yokohama Sanbo Hall Marineria is open 24 hours daily, you'll need to confirm with the venue directly whether booking an event at 3 AM carries additional premium rates or has minimum rental duration requirements. Extended hours don't always equal unrestricted access, so clarify their specific after-hours policies and any surcharges when you contact them.

The venue listing doesn't specify standard inclusions like tables, chairs, sound systems, or catering facilities. Contact the team at +81 45-671-7050 to request a detailed amenities list and identify which items are provided versus what you'll need to source from external vendors or negotiate as add-ons.

Located in central Yokohama's Naka Ward, the venue has reasonable access to public transportation and is approximately 40–50 minutes from Narita or Haneda airports via train. However, confirm parking availability and whether the venue can accommodate large shuttle services if you're expecting significant international attendance requiring ground transportation coordination.

Event venues in Japan typically require direct communication for customized quotes. Plan to call +81 45-671-7050 with your event details (date, expected attendance, room setup, required amenities), and allow 5–7 business days for them to provide a formal proposal and negotiate terms before confirmation.

Capacity isn't listed in available information, which is unusual for an event venue. This could indicate flexible, modular spaces or simply incomplete online documentation. Request specific numbers for your anticipated guest count and ask about maximum occupancy limits to ensure the venue can accommodate your event size.

Since pricing requires direct contact, request itemized quotes including room rental, standard amenities, and any time-based surcharges. Compare 3–4 similarly located Yokohama venues using the same detailed criteria (setup hours, AV equipment, catering options) to benchmark value rather than relying on base rates alone.
