About this tour
When Jake from our team tried this experience in Sabae, Fukui, we got a rare peek behind the scenes at Inui Lens, one of Japan's serious lens manufacturers. The hour-long session walks you through how quality optical lenses actually get made, then you get hands-on: pick from over 300 lens colours and fit them into your own frame to craft a custom pair of sunnies. It's a proper bit of Japanese craftsmanship, and afterwards you cool off with coffee or soft serve at the on-site café. The whole thing feels less touristy gimmick, more genuine factory visit.
Highlights
- Factory floor access — see lens production machinery in action, rarely shown to visitors
- 300+ lens colours to choose from — creates genuinely one-off specs
- Hands-on assembly — you actually fit and complete your own pair
- Learn the optics — brief but solid explanation of the lens-making craft
- Soft serve or coffee break included — nice wind-down after the activity
- Compact one-hour slot — fits easily into a day itinerary
- Small-group setting keeps it intimate and personal
What to expect
Jake walked in, got a quick rundown of how Inui Lens operates and the technical side of lens production. The factory tour isn't a huge sprawl — it's focused and efficient, showing you the core machines and processes that most tourists never see. Then comes the fun bit: you're given access to the colour palette and frame options (or you bring your own frame), and you pick your lens combo, then slot it into place yourself under guidance.
The pacing is brisk but not rushed. You're not standing around waiting. By the end of the hour you've got a finished pair of custom sunnies in hand, genuinely tailored to your taste. The café break afterwards is a natural cooldown — grab an ice cream or espresso and sit with your new purchase. It's low-key, not overly choreographed.

Good to know
This works brilliantly if you actually care about sunglasses or optics. You're learning from a real manufacturing operation, not a souvenir workshop. If you forgot your frames or don't have any, you can buy one on-site, but that's an extra cost. The activity suits absolutely anyone — you don't need fitness or prior experience. Public transport gets you there easily enough.
You need to bring your own eyeglass frames unless you want to pay extra. The hour is genuinely short, so don't expect a leisurely pace. Sabae is a regional town, not a major tourist hub, so logistics matter — private transport isn't included. The experience is tailored and intimate, which is great, but that also means it's not a big-group party. Peak times aren't flagged, so book ahead if you're visiting a busy season. Weather doesn't affect this one since it's indoors.
