I’ve come with some other morsels for vegetarians (I’m not, sorry, but I do commiserate!):
Above is a tenpura made with seasonal mushrooms in Takasagotei Izakaya in Hamamatsu.
Actually you could eat almost any edible mushrooms this way!
This particular fine (thin) leafy plant is called “Ashitaba”. It is quite common and very cheap in our Prefecture and all over Japan. It just shows how you cantry any leafy plants. There is no limit to it! I ordered the above at Oikawa Izakaya in Shizuoka City.
Now, this one is bit more exotic/ethnic as this is kimchee tenpura, which shows that tenpura knows no frontier. Crunchy, it has plenty of texture. Was served at Oikawa Izakaya in Shizuoka City.
