Our tour guide, Kevin, was excellent, thoughtful, and humorous, making the entire trip very enjoyable. Kevin deserves half the credit for this itinerary! Lake viewing was the highlight of this tour, with the small fireworks display at the end serving as a nice embellishment. The tranquility of the lake was truly refreshing for both mind and body. Regarding the bear farm admission and the final fireworks cruise, both are optional. Personally, I recommend skipping the bear farm and spending that time seeing Showa Shinzan instead, as it's more worthwhile. For the fireworks cruise, while it offers a panoramic view from the lake (the fireworks boat moves around, so you might only see parts from the shore), it only lasts about 25 minutes (around 8:45 PM - 9:10 PM Japan time). You can decide if it's worth it for you.
