I'm searching tourism venues of Kyokutei Bakin and Hakkenden.

Now, I'm searching tourism venues of Kyokutei Bakin and Hakkenden, such as Fusehime Rouketsu/Fusehime Caves, the former Takita Castle and so on. But, actually, it's very difficult. Kyokutei Bakin's birth venue is Fukagawa in Tokyo, but the tourism venues of Hakkenden, including Fusehime Rouketsu, is very far from the station. I have to use the taxi much times. Is it that Tateyama is very car-centric society? Of course, it's accessible for me to go to Tateyama Castle, the castle of Inue Shinbei who is the one of Hakkenshi. But, for me, it's not sufficient of that. In May, I want to go to Tokyo and Tateyama, the oriented venues of Kyokutei Bakin and Hakkenden. But I have no cash, it's difficult. Should I sell the stock of Kao, or should I postpone the travel by July?
