創造硝子工房 studio J-45

Tucked into the craft-proud streets of Otaru, Studio J-45 is the kind of place that rewards the curious traveller willing to step off the well-worn canal path. This boutique glassblowing workshop invites visitors to try their hand at a tradition Otaru has quietly championed for generations, and the results, shaped by your own breath and steadied by a skilled guide, leave with you as something genuinely irreplaceable. With a 4.8-star rating across over a hundred reviews, the warmth of the experience speaks for itself.

When to go

Otaru's cooler seasons lend a particular magic to any indoor craft session: the glow of the furnace feels especially welcome in autumn and winter. Arriving early in the day generally means a more relaxed, unhurried atmosphere in this small studio setting.

“Had the best time doing the glass blowing workshop. The instructions were clear and staff was incredibly nice. They even made sure to bring our glasses to the hotel we were staying in in Otaru. And the glass we made came out so beautifully 🤩 This is definitely a highlight of our trip!”— Rohdé te Paske, Google review
