Even though it hasn't opened in Japan yet, people are already saying it’s bound to be the biggest blockbuster movie of 2026~!

[Chiikawa] Follow-up report & additional cast announced! Let's review the synopsis of the theatrical Chiikawa movie releasing next month!

New trailer released! Voice actors for key characters like the Siren and Shimajirou have been announced! Let's review the synopsis before the premiere!

Wow~! We are so close to the release date! The follow-up report for the Chiikawa movie, which is incredibly famous not just in Japan but worldwide, has dropped, so let's check it out right away!

Chiikawa and friends arrive on a tropical island for a trip. However, that island hides...... a ve~ry terrifying secret!

In our previous article, I explained it as a story where Chiikawa and friends go to visit a tropical island mentioned on a flyer! They headed off to the southern island in high spirits. The islanders were very kind and friendly...... but surprisingly, a giant Siren has been appearing on the island, kidnapping the residents one after another, and people have gone missing! They are asked to subjugate this Siren! Chiikawa and the gang, who thought they were just on vacation, try to take down the Siren, but...... it seems the Siren and her group have their own circumstances......?

Voice actors have been cast for the key characters, the Siren and Shimajirou! The theme song “Kutsuzure” sung by Hachiware has also been revealed, packing plenty of new info that makes it hard to wait!

The voice actress for the Siren has been decided as Minori Suzuki! Minori Suzuki is a female voice actress who has recently been active as Agnes Digital in Uma Musume and Liko in the Pokémon TV series! Since she also handled singing roles in the Macross series, she has a reputation for being an excellent singer!

And the voice actor for Shimajirou is Tsuguo Mogami! He is skilled at characters with deep, rugged voices who still possess a sense of playfulness. Personally, he leaves a strong impression from playing Mr. Compress in My Hero Academia! Neither of them can be called a rookie anymore; they are super seasoned, talented veterans, so we can watch with complete confidence!

As for the theme song 'Kutsuzure' (Shoe Sore)...... fans were confused at first, wondering if it was a brand-new track, but the manga updated last night and revealed it's a song written, composed, and performed as an acoustic solo by Hachiware! 'Keep walking even if the shoe sore hurts, never give up! ......But after all, shoe sores really hurt, so you end up crying anyway.' It’s a gentle, peaceful song that perfectly embodies Hachiware!

To recap, the movie premiere date is July 24th! Everyone, please be sure to check out this new film~!
