Traveling with Host Family

On Saturday, my host family and I went on a little trip. First they took me to see a geiser, where we also took a foot bath/onsen/hot spring. Afterwards we went to see some ruins/excavations. I didn't really understand their history well, because everything was in Japanese. But from my host dad I understood they were approximately 3000 BC.
Afterwards, host dad made some Japanese styled BBQ. It was delicious and I got to try out some new seafood, like kagi. It was good, even though slightly bitter. But apparently not even all Japanese people can eat it, like my mom. In any case, once again they are great and I got lucky with them.
