This summer marks the park’s first holiday season since its renovation. To help families create unforgettable memories, we are pleased to announce that children’s admission will be completely free during the 'Jabu Jabu Pool' opening period from Saturday, July 18, to Monday, August 31.

Throughout the period, a wide array of experiential content starring children will be available, including the 'Jabu Jabu Pool' – where a powerful 'Bubble Bazooka' erupts every weekend – 'Free Research Events' to complete summer homework in one day, the 'Kids Job Experience Pass,' and the two-day limited nighttime special opening 'Nakori Festival Flower Hour' during the Obon holiday.

We also offer special events for adults to enjoy their summer.

As the stunning naturalistic garden – where herbs and perennials harmonize – reaches its peak season, we will host free floral events such as flower arrangements and producer talk shows, along with luxurious peach desserts.

We invite your entire family to experience the new summer at our flower park.

Over 13,000 Blooms of Yellow and Blue: Sunflowers and More

The summer flowers now in full bloom feature a bold east-west color contrast in the main flower garden, creating a striking visual highlight.

A total of over 13,000 vibrant yellow and blue flowers create a breathtaking summer landscape. The radiant yellow of sunflowers and rudbeckias – bright as the sun – contrasts beautifully with the cool blue of salvias against the summer sky.

The eastern garden showcases five varieties of sunflowers, the stars of summer. Immerse yourself in the unique charm of each sunflower variety.

The western garden blends massive volumes of rudbeckias with refined blue salvias, creating a vivid and striking collaboration of yellow and blue under the summer sky.
