Nijigen no Mori, the anime theme park inside Hyogo Prefectural Awajishima Park on Awaji Island, has added a Hange-themed drink to the menu of its TV anime Attack on Titan collaboration event, on sale since October 1, 2026. The park's operator detailed the item in a PR TIMES release published on October 14, 2026.
The drink is listed as 「じ…じゃあ…実験していいよね？ハンジの実験ドリンク」, which translates roughly as "W-well... it's okay if I experiment, right? Hange's Experiment Drink." It costs ¥1,200 including tax and is served at Morino Terrace, the park's restaurant.
Each serving comes with a separate "experiment powder." According to the release, adding the powder makes the drink's color change gradually. The release describes the drink as modeled on the curiosity of Survey Corps squad leader Hange and on the experiments shown repeatedly in the series.
The menu item is part of the Attack on Titan collaboration event, which Nijigen no Mori is running from March 14 to December 13, 2026. The nighttime program, Attack on Titan THE NIGHT WALK, leads participants along a 1.2-kilometer forest trail where projection mapping and sound recreate the anime's world. Daytime options include a stamp rally and the Mystery Quest puzzle events; in the main Nijigen no Mori quest, visitors follow the clues left behind to search for their missing superior officer, Hange Zoe.
Night walk admission is listed at ¥3,600 to ¥4,000 for ages 12 and up and ¥1,600 to ¥2,000 for ages 11 and under, with prices varying by season. The release notes that the details it lists are subject to change.
