Next time you go to Japan, please take a look at buses to if they are clean.
No, it is not PoKe. PoKe is getting popular in the US, but this is Japanese style seafood bowl. You can get one in many places in Japan and the price ranges from 800 yen to 2,000yen. I think the one you are looking at is 1,200 yen in Ameyoko Tokyo.

Lessons are best suited to those who have basic understanding of hiragana and katakana alphabets before moving on to the more advanced grammar and particle lessons.

Kanji is used in the lessons with hiragana and English translations provided.
