Heso Production has announced new Myaku-Myaku Kuru Toga and Jetstream 4&1 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.
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 |
|---|---|---|
| Kuru Toga: ivory, coral pink, iron blue | 0.5 mm pencil | ¥1,500 each |
| Jetstream 4&1: ivory, night blue | Four 0.5 mm ballpoints; 0.5 mm pencil | ¥2,300 each |
| Jetstream 4&1: soft pink | Four 0.38 mm ballpoints; 0.5 mm pencil | ¥2,300 |
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 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.
