We departed at 9:00 AM on August 3rd. The original itinerary included the Hakkoda Ropeway and the Shiokura Bridge, but we wanted to spend more time on the Oirase Stream, so we started directly from Tsutsumuma. It took us an hour and a half to get from Asamushi Onsen to Tsutsumuma. Our driver, Mr. Nakatani, even provided several bear bells for us to wear and accompanied us throughout the journey. We arrived at Ishigado Rest Area around 11:00 AM. Mr. Nakatani led us from Ishigado to Mamondei, then we took a ride along the way to take photos or walk for a while, arriving at the lakeside plaza of Lake Towada around 1:30 PM. We had lunch there and stayed until 3:00 PM, returning to Aomori Station around 5:00 PM. The timing was perfect, and although there was a language barrier, the translation software was sufficient for communication. Thank you, Mr. Nakatani!
Mr. Toyoshima drove smoothly, and despite the language barrier, he diligently provided explanations for each attraction using a translator. A day trip to the Hakkoda Ropeway, Oirase Stream, and Lake Towada was possible, with ample time to explore each site. It's truly a blessing for those without a car, and highly recommended.
