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

"When visiting Hakone, it's important to respect the local customs and traditions to avoid any cultural faux pas. Firstly, never wear your shoes inside a home or traditional establishment, such as a ryokan (Japanese inn) or an onsen (hot spring). Instead, use the slippers provided. When visiting an onsen, remember to wash your body thoroughly before entering the hot spring. It's also considered impolite to put your towel in the water, so place it on your head or the side instead. In terms of dining etiquette, never stick your chopsticks upright in a bowl of rice as it's associated with funerals. Also, avoid passing food from chopstick to chopstick, as this is another funeral-related custom. When interacting with locals, avoid making direct eye contact for too long as it can be seen as confrontational. Also, remember that the Japanese often express disagreement or refusal indirectly, so pay attention to subtle cues. Avoid tipping as it's not customary in Japan and can sometimes be seen as insulting. Instead, show your appreciation with a polite thank you. Lastly, remember to always be punctual. Being late is considered very rude in Japanese culture," remarked another expat in Hakone, Japan.
