Hobonichi MOTHER Project to Open “MOTHER no SUMMER” at Seikatsu no Tanoshimi Exhibition 2026

Hobonichi Co., Ltd. will hold the early-summer “Seikatsu no Tanoshimi Exhibition” from June 1 to June 7, 2026, where the Hobonichi MOTHER Project will open “MOTHER no SUMMER.” This year’s theme is summer, the outdoors, and adventure. To welcome the coming season, the project has named the event “MOTHER no SUMMER.” The lineup includes backpacks, T-shirts, sneakers, parasols, water bottles, sandals, and beach bags inspired by Nintendo’s MOTHER game series. Since the theme is “SUMMER,” the Summers replica screen will also return in a limited resale. Ahead of the exhibition, new products, excluding some items, will go on sale at the online “MOTHER no Omise” store from 11:00 a.m. on Monday, May 25. Whether in the city or at any age, the project invites fans to enjoy an exciting summer full of adventure. MOTHER is a role-playing game planned, written, and produced by Shigesato Itoi. Nintendo released three titles: MOTHER for the Family Computer, MOTHER 2: Gyiyg Strikes Back for the Super Famicom, and MOTHER 3 for the Game Boy Advance, released only in Japan. The series’ distinctive dialogue and worldview continue to attract many game fans today. The new product lineup includes the MOTHER parasol, a rain-or-shine umbrella with a 64% heat-blocking rate and over 99% UV protection and light-blocking performance. It uses Toray’s Summer Shield fabric, carbon ribs, and a large 60 cm folding-umbrella size. Price: 16,500 yen including tax. The DRY T-shirt uses original 100% polyester fabric with quick-drying, antibacterial deodorizing, and 94% UV-cut functions. The front chest features embroidered protagonist artwork, while the back is printed with lyrics from the MOTHER song “Pollyanna (I BELIEVE IN YOU).” Price: 4,950 yen including tax.

These caps feature subtle embroidered Mr. Saturn pixel art on a richly dyed purple body and a stylish beige body. Each is priced at 7,480 yen including tax. The Franklin Badge backpack keeps the feel of MOTHER and Ness while creating a modern backpack for everyday use. It was made by FREDRIK PACKERS with a focus on practicality.
