Understanding cash usage and tipping customs is pivotal for a seamless journey during your self-guided bike tour in Japan. While credit cards are widely accepted in urban areas, carrying a reasonable amount of cash is advisable, particularly when venturing into more rural regions where cash might be the preferred mode of payment. Remember that tipping is not customary in Japan and can sometimes even be perceived as impolite. Excellent service is already included in the price, so there’s no need to leave gratuities at restaurants, hotels, bike shops or other establishments. Embracing this cultural aspect allows you to engage authentically with the local way of life and ensures your interactions are grounded in respect and appreciation for Japanese traditions.
