SAKAKI Gear is the outdoor brand of Sakakibara Kouki, a 12-person precision machining shop in Kasugai, Aichi, Japan. Our day job is industrial parts. The lantern covers are cut on the same machines, by the same people, to the same tolerances. This page explains how a cover is made, how it is checked before it ships, and what you should check before you use it.
How a cover is made
Every cover starts as a bar of solid brass or aluminum. Nothing is cast, stamped, or formed from sheet, which is why a brass Akatsuki weighs about 450 grams and why the walls can be cut thin without going out of round.
Cap, body, and bottom ring are turned separately. The threads that hold the Goal Zero light in place are machined, not rolled, so the ring goes on hand-tight and stays there.
Brass is polished and left bare, so it will darken into a patina with use. Aluminum is anodized: a hard oxide layer dyed silver, gunmetal, or wisteria that does not tarnish or chip.
Each piece is checked by hand for finish and thread fit before it goes into its dedicated case with export packaging. The case is there to keep the cover from meeting a tent stake in a gear box, and it works.
Why a machine shop makes lanterns
We have tried to sell our own products twice before: precision golf putters to Russia, frozen by the invasion, and again to China, refused at the border. The lantern covers began as a domestic crowdfunding project, where more than 1,100 backers funded Akatsuki and Mahoroba before they were products. This English store is the third attempt, and the first one where the customer buys directly from the shop that made the piece. Our Story has the long version.
Before you use it
Akatsuki and Mikasa fit the Goal Zero Lighthouse Micro Flash only. Hatenaki and Hajimari fit the Micro and the Micro Flash. Nothing fits the Micro Charge. Kizashi is for the Ledlenser ML4. The compatibility guide shows how to tell the lights apart.
Only the Hajimari Set includes a Goal Zero light. Mahoroba includes an oil burner kit. Every other cover arrives without a light; you fit it over your own.
Check the threads and the finish before first use. If anything looks damaged, does not seat, or does not thread smoothly, do not force it. Email us photos and we will replace or repair it.
The cover does not change how the Goal Zero light charges or runs. Keep the charging port and the switch reachable, and do not block ventilation on any light you put inside a cover.
Tamayura and Mahoroba in oil mode are real oil lamps. Use paraffin lamp oil, fill outdoors, never leave a flame unattended, and let the brass cool before handling. Keep away from children, pets, and tent fabric.
Brass darkens, picks up fingerprints, and can be polished back. Anodized aluminum shows scratches as lighter lines. Both get cold in winter and warm in sun. The care guide covers cleaning and storage.
Why this page exists
You cannot visit the shop or hold the piece before you buy it, so we have tried to put on paper what you would see if you could: who cuts it, how, what is in the box, and what to look at when it arrives. If anything on this page does not match what you receive, tell us. We read every message from the shop floor.
