This listing is for a vintage happi coat - typically worn for parades or festivals, and usually decorated with auspicious designs or kanji that refer to an event sponsor, community organization, or even the town government.
We think the characters on the front of this jacket spell out the name of a company sponsor, but we cannot translate it. There is a small crest-like element - perhaps the company logo? - on the back of the neck, which is quite unusual. The shape that surrounds the kanji is a weight motif, used for measuring rice and other items.
A deep indigo blue with lighter gray-blue bands across the shoulders, and a large white stylized kanji on the back.
There are blemishes on each sleeve - see photos - but still quite wearable or great as a display piece.
See videos below for how Japanese indigo is processed and the fabrics are dyed and woven.
