[Heso Production](https://www.heso-pro.com/?ref=news.knockology.com) has announced new **Myaku-Myaku** [**Kuru Toga**](https://www.mpuni.co.jp/?ref=news.knockology.com) **and** [**Jetstream 4&1**](https://www.mpuni.co.jp/?ref=news.knockology.com) designs for a **mid-June 2026** Japanese rollout. The June 9 release extends the **Expo 2025 licensed** merchandise range into the following year.

[Myaku-Myaku is the official character of Expo 2025 Osaka, Kansai, Japan](https://www.expo2025.or.jp/en/overview/Character/?ref=news.knockology.com).

The lineup brings three Kuru Toga colors and three multipen colors, but the Jetstream choice also changes the ballpoint tip size:

| Instrument and colors                   | Writing specification                  | Japanese price before tax |
| --------------------------------------- | -------------------------------------- | ------------------------- |

That soft-pink specification is the detail to catch before ordering: all three multipens have the same pencil lead size, but the pink version has finer ballpoints. The prices in [Heso Production’s announcement](https://prtimes.jp/main/html/rd/p/000000687.000026530.html?ref=news.knockology.com) are explicitly before tax.

## Where the rollout starts

The listed channels include the official Expo 2025 stores at Eki Marché Shin-Osaka and the Eki Marché Osaka pop-up, along with station shops, souvenir shops and variety stores in the Kansai area. Heso says introduction timing varies by location.

The mid-June window therefore describes the start of distribution, rather than a synchronized arrival at every shop. The 2025 license branding remains part of the product identity even though these color editions are a 2026 release.
