Thanks to our tour guide Jingxia for her explanations. We were very lucky this time; the icebreaker set sail smoothly, and the drift ice was in good condition. Although it didn't reach the shore, it was still spectacular. The only minor regret was that the time spent at the icefall festival was a bit short, but since it was already late on our return trip, we couldn't extend it. Overall, the trip was excellent despite its minor flaws.
Director Jiang was very attentive, explaining the surrounding items and historical stories clearly, which helped me learn more about Hokkaido. The food along the way was delicious, the hot spring hotels were fantastic, and the buffets were luxurious. I especially loved the snow activities at Shiki no Iroha – they were so much fun! Overall, the only downside was not seeing any drift ice... I would definitely participate again next time.
