Edo-kiriko is one of 2 great glass traditions from Japan; the glass is thick, feels similar to Murano glass, with the edges of the cut pattern "sharp".[0]
There is also a tradition of thin glass (without etching), where the glass is blown to be paper thin and you can feel it flex as you hold it.
This is called Usuhari - "Usu" means thin and "Hari" means glass[1]. Shotoku is the best maker, creating a variety of specialty drinking glasses of many shapes.
I have a small collection of Japanese drinking glasses at home which I use regularly and freely use with friends[2] - everyone loves drinking beer or sake from the Usuhari glasses. Shotoku actually did a collaboration with one of the Edo-kiriko makers, by blowing a small sake cup with a thick Usuhari glass ~ it's amazing, and I use it as my personal spirits cup.
[0] Not sharp enough to hurt, yet very noticeably present.
[1] usuhari glasses are exceptionally thin at 0.9mm. Paper is ~0.1mm, so I'm slightly exaggerating.
[2] less expensive than the Edo-kiriko.
