① 交通① 交通① Getting around
秘境多半在鐵路支線或巴士的盡頭。IC 卡（Suica / ICOCA）幾乎全國通用，先在機場買一張。跨區長距離再視情況考慮 JR Pass——短程或只玩一區時，單買車票通常更划算。 秘境多半在铁路支线或巴士的尽头。IC 卡（Suica / ICOCA）几乎全国通用，先在机场买一张。跨区长距离再视情况考虑 JR Pass——短程或只玩一区时，单买车票通常更划算。 Hidden spots often sit at the end of a branch line or bus route. An IC card (Suica / ICOCA) works almost nationwide — grab one at the airport. Consider a JR Pass only for long cross-region trips; for short or single-region travel, single tickets are usually cheaper.
② 支付與現金② 支付与现金② Payment and cash
大城市刷卡與行動支付普及，但鄉下的秘境常常只收現金。神社、小食堂、山中民宿尤其如此。出發前準備一些日圓現金，並記下哪裡有 7-11 的 ATM（可用海外卡提款）。 大城市刷卡与移动支付普及，但乡下的秘境常常只收现金。神社、小食堂、山中民宿尤其如此。出发前准备一些日元现金，并记下哪里有 7-11 的 ATM（可用海外卡提款）。 Cards and mobile payment are common in big cities, but rural hidden spots are often cash-only — shrines, small eateries, and mountain inns especially. Carry some yen, and note where 7-Eleven ATMs are (they accept overseas cards).
③ 基本禮儀③ 基本礼仪③ Basic etiquette
神社境內輕聲、不佔道拍照、垃圾自己帶走。溫泉入池前先洗淨身體。這些不是規定，而是日本人默契的一部分——做到了，在地人會用完全不同的態度對待你。詳見日本人與文化。 神社境内轻声、不占道拍照、垃圾自己带走。温泉入池前先洗净身体。这些不是规定，而是日本人默契的一部分——做到了，在地人会用完全不同的态度对待你。详见日本人与文化。 Keep your voice low at shrines, don't block paths for photos, take your trash with you, and wash before entering an onsen. These aren't rules but shared understandings — follow them and locals treat you differently. See People & Culture.

秘境的美很吃季節：夏天避暑的溪谷、秋天的楓、冬天的雪屋。山區日夜溫差大，六月中～七月是梅雨。每一篇秘境景點都會標註「最佳季節」，照著安排就對了。 秘境的美很吃季节：夏天避暑的溪谷、秋天的枫、冬天的雪屋。山区日夜温差大，六月中～七月是梅雨。每一篇秘境景点都会标注「最佳季节」，照着安排就对了。 Hidden spots depend heavily on season: cool summer gorges, autumn maples, winter snow huts. Mountains have big day-night temperature swings, and mid-June to July is the rainy season. Every hidden spot guide notes its best season — plan around that.
