I couldn't wait to leave the volcano owing to the heat. The following stop was the city of Kagoshima but we had to take a ferry to cross the Bay of Kagoshima (called Kinkowan by the Japanese) otherwise it would take more than an hour for the coach to meander along the coastline. It was an automobile ferry. We got off the coach and went to the top deck for some cool breeze and sight-seeing. Drink vending machines are everywhere in Japan, even on ferries! The journey took the ferry only a bit more than 10 minutes.
Shown below is a panoramic view of the city of Kagoshima taken from the Kinkowan ferry:

Except Naha of Okinawa, Kagoshima is the southernmost city of Japan. It is well-known for its extreme proximity to an active volcano, namely Mount Sakurajima. The only other city in a similar situation is Napoli (Naples) of Italy which is twice as far from neighbouring Vesuvius Volcano than Kagoshima is from Sakurajima Volcano. It seems a foolish idea to build a city near an active volcano, but since Sakurajima is continually active and venting off pressure it is not likely to explode in a violent eruption. Volcanic ashes, however, can be a problem to the people. Weather forecasts for Kagoshima often take volcanic ashes into account. The four seasons are distinct and is significantly warmer than northern cities like Sapporo & Otaru. Typhoons do occasionally hit the city. Typhoons advancing to latitudes as high as Kagoshima usually move fast and steadily. This means that if you are in Japan standing in the path of an approaching typhoon then you'd better take all precautions for a sure direct hit.

We didn't do much but window-shopping mainly along the Tenmonkandori (Planetarium Street) Shopping Mall. We made an excursion into Mitsukoshi Department Store where we saw some automatic bank teller machines. We tried in vain to get some cash from the machines with our credit cards. We even tried those in banks but again to no avail. Banks in Japan are generally very tourist-unfriendly.
