The delicate hand of the lacquer ware maker applies gold leaf to the speaker’s cavity creating the original Japanese product, SEIGETSU.
The name for SEIGETSU, (青月) “blue moon” in Japanese, comes from the popular romantic song, “Blue Moon”:
And then there suddenly appeared before me
The only one my arms will ever hold
I heard somebody whisper, “Please adore me”
And I looked the moon had turned to gold
Ordinarily, there are many steps taken in the process of applying gold leaf to a lacquer ware product. But with SEIGETSU, no lacquer is applied to the speaker. The lacquer ware maker uses his delicate hand and exquisite craftsmanship to apply the gold leaf in the small cavity of the speaker, a task that is difficult and time consuming for even a veteran to accomplish.
