Near the torii gate, which serves as the entrance to the event venue, a tunnel decorated with bamboo and floral balls creates a powerful visual presence. It is also an ideal spot for photography.

● A Cool Night, 5°C Cooler Than Lowland Areas – Only Possible in Unzen, a Summer Retreat

Located at an elevation of approximately 700 meters, Unzen offers a uniquely refreshing nighttime experience, remaining comfortably cool even in summer. Enjoy a pleasant evening breeze and a special ambiance as you stroll in your yukata after a relaxing hot spring bath.

Weekday-Only Discount for Overnight Guests

A special discounted admission price is available exclusively for overnight guests on weekdays. While the regular weekday admission for high school students and above is 1,000 yen, overnight guests can enter for just 800 yen.

Currently, overnight guests rarely leave their inns or hotels at night, leading to a lack of evening activity throughout the hot spring district. To address this, we have introduced a special discount exclusively for overnight guests.

※ No discount is available for middle school students and below, as admission is already uniform.

Preview Event for Stakeholders

Ahead of the official launch of 'Unzen Ryōkato – Yomiyu of Hell,' we will host a preview event for stakeholders.
