I completely recommend it. Unfortunately, Daikoku was closed on the day of the reservation, but that didn't ruin our tour. Our first driver was Lío in his Nissan; he took us to Tokyo Tower for a couple of photos, and then we sped off to Umihotaru with great music playing. We arrived at Umihotaru and had a fantastic time, seeing a ton of JDM cars and even American muscle cars. Then, because our Airbnb was in Kawaguchi, the tour team solved the transportation issue by switching drivers, and this new driver took us right to the door of our Airbnb. Everyone was very kind and "good vibes"; they even let us play our own music and gave us a sticker to remember the trip. I completely recommend this experience, even for people who aren't car enthusiasts. I wish the Takumi Crew all the best.
