What cultural faux pas should I try to avoid making in Sapporo?

"In Sapporo, it's considered rude to eat or drink while walking in public. It's best to consume food and beverages at the place where you bought them or at home. Avoid tipping in restaurants, taxis, or hotels as it's not customary in Japan and can sometimes be seen as insulting. When using chopsticks, never stick them vertically into your food, especially rice, as this is a practice associated with funerals. Avoid blowing your nose in public as it's considered impolite. If you need to, excuse yourself and go to a restroom. It's considered rude to point at people or things with your finger. Instead, use your whole hand to gesture. Avoid speaking loudly in public places, especially on public transportation, as it's seen as disrespectful. When entering a traditional Japanese home or certain restaurants and tea rooms, you should remove your shoes. Avoid interrupting people while they are speaking. It's considered polite to wait for your turn to speak. In Japan, it's customary to bow when greeting someone. The deeper the bow, the more respect is shown. Avoid making physical contact, such as hugging or patting on the back, as it's not common in Japanese culture. It's considered impolite to refuse a drink from a host or to leave food on your plate. Try to consume what is offered to you. When giving or receiving something, use both hands as it's seen as respectful," remarked another expat in Sapporo, Japan.
