Again my Japanese is very basic, but I'll try from experience.
Tanaka- Soba mochi served with dashi- Century Old Egg(Its delicious, good with rice and congee. Takes some getting used to because its very intense and it stinks)
Endou- Fried crickets + soju(Korean rice wine, similar to sake)
mochi- Frisk mochi!Yamasaki- Habanero potato rings mochi- Natto, okra, tororo mochi(Made from grated yamaino, a type of yam)
I eat it often in soups and its suppose to be very healthy, but its almost flavorless. Theres a dried and the more expensive fresh version, Id prefer the fresh root.
Hamada- Sashimi mochi(That just sounds unappetizing)
- Ochazuke mochi(Pickled vegetables/fruits, seaweed, dried fish,etc served with tea, water or dashi)
Matsumoto- Candy Apple mochi
- Pop Rocks mochi
- Wedding cake mochi with the cake topper
