At the beginning of April, I went to Aomori prefecture by newly debuted high-speed ferry, nicknamed Nacchan Rera. A special discount ticket called "Kurumawari" which was offered until the end of March first, but extended until the end of May later. You can't use the discount ticket during Golden Week(Apr.26-May.6), but it costs 20,000yen(about US$200) for a car and five passengers. If your car's capacity is eight, the company offeres the same price. Don't you think it's great price?
The high-speed ferry takes you to Aomori from Hakodate crossing the Tsugaru Straits in two hours. How about going to Aomoiri by your own car?
I'll write about tourist attractions in Aomori in later posts.
