Multiglass somerso bird hashioki, includes designer/artist (?) names

These five hashioki are about 2.75" long x 1.5" wide x 1" high. The bottoms are ground flat and matte polished. They came in a fancy, silk lined hinged box, made of rich, textured paper with a thin cardboard sleeve that slides over the box. This set is several decades old but in new condition.

The hashioki are not signed but came with a copious amount of documentation; two loose papers and two box labels. One paper appears to refer to the designer and the other to the glass artist? I could find nothing for either name. Perhaps they will be familiar to Karen (I hope). At any rate, I think that this is a significant documented set.

The loose papers say:
"Takumi
Glass Product
A soothing Japanese atmosphere of the four seasons.
Takumi,the glass craftsman, put them into a container.
This is a masterpiece made of fragrant glass.
Utensils created by long tradition and reliable technology.
A sophisticated vessel worthy of being called a craftsman.
Please enjoy the chic and stylish atmosphere.

Hiroshi Takada

The label on the box lid says:

"Takumi
The curve of glass"

So, I think Takumi made these and they were designed by Hiroshi Takada? Just my take on the labels. The other label, which is on one end of the box, is probably a stocking label.
