In a refreshing initiative, PRONTO Corporation, headquartered in Minato, Tokyo, is set to introduce a new drink size called 'Giga Size' in its cafes starting June 9, 2026. This limited-edition offer comes just in time for summer and is designed to amplify the experience for customers seeking larger servings.
Building on the success of last summer's 'XL Size', which received enthusiastic feedback from customers, PRONTO decided to take it a step further. The 'Giga Size' is now officially the largest drink size ever offered by the chain. Customers can look forward to indulging in three summer chilled beverage options: iced coffee, iced cafe au lait, and watermelon juice, all available in the spacious 'Giga Size'. Notably, this new size offers about 2.5 times the volume compared to the regular size, while the 'XL Size' offers roughly 1.8 times more than the regular option.
The 'Giga Size' will feature a charming polka dot-patterned cup adorned with the word 'Giga', giving it a pop-art feel suitable for the summer vibe. This fun and whimsical design is intended to enhance the overall enjoyment experience as it stands out during casual outings or quick breaks throughout the day. Whether you're stopping by before work, heading for a lunch break, or simply lounging during leisure time, the 'Giga Size' products aim to make those moments even better.
Product Pricing (inclusive of 10% tax):
1. Iced Coffee: R size 396 yen, L size 484 yen, XL size 550 yen, Giga 660 yen.
2. Iced Cafe au Lait: R size 440 yen, L size 528 yen, XL size 594 yen, Giga 704 yen.
3. Watermelon Juice: R size 550 yen, L size 693 yen, XL size 781 yen, Giga 935 yen.
The 'Giga Size' drinks will be available at all PRONTO locations from June 9 to September 28, 2026. However, they can only be enjoyed during café hours, excluding ‘Sakaba Time’. Customers are encouraged to check the specific operating hours of their nearest PRONTO café on their website.
PRONTO aims to be the 'GREAT GOOD PLACE' for all customers, combining the functionality of a café by day and a social bar by night. Their philosophy revolves around being a convenient gathering spot, where people can connect and enjoy their time, no matter the hour. The brand effectively merges work and leisure, inviting individuals to come in for coffee before work and unwind later with friends over drinks.
