Hamamatsu Festival Happi Coat - Almost Unused

This is a Happi coat for the Hamamatsu Festival, purchased at a festival goods store during a visit to Hamamatsu around 1990!
If my memory serves me correctly, I bought it for 30,000 yen at the time...
I only wore it once at home and have kept it in my chest of drawers.

The pattern on the sleeve lining is also stylish!! (See image 1)

Vertical length (excluding collar): approx. 97 cm
Horizontal length when sleeves are spread: approx. 132 cm

Perhaps due to long-term storage, there is some yellowing on the back lining (the white cloth inside the shoulders) and at the bottom of the Hamamatsu characters on the back. (Image 6)
It's unclear if washing will remove it.

I would like to pass it on to someone who will cherish it!

Please refrain from price negotiations☆
