额外:清真饮食的月度成本影响

对于穆斯林马来西亚工程师,饮食成本有特殊影响:

halal_food_impact = {
"东京清真饮食成本估算": {
"自煮(自己买清真食材做)": "¥40,000–50,000/月(略高于普通自煮,清真食材有时更贵)",
"外食(仅清真餐厅)": "¥65,000–90,000/月(清真餐厅选择少,价格通常高于普通餐厅)",
"混合(自煮+偶尔清真外食)": "¥45,000–60,000/月",
"说明": "比非清真饮食贵约15–25%,因为选择受限且清真认证产品较少",
},
"采购渠道": {
"超市清真肉类": "成城石井、Hanamasa(肉类专门店)、部分AEON大型超市",
"在线购物": "Amazon Japan 有清真认证产品,种类逐年增加",
"东京清真超市": "代代木上原清真寺区域、麻布/広尾有中东系超市",
"大阪": "鶴橋(韓国街)附近有清真食材店",
"福冈": "清真选项更少,需要更多自煮准备",
},
}

年度大额支出(容易忘记的)

annual_big_expenses = {
"回马来西亚机票(每年1次)": {
"价格范围": "¥70,000–130,000 JPY(来回)",
"换算MYR": "约 RM 2,240–4,160",
"淡旺季差异": "农历新年/年末旺季价格翻倍",
"建议": "提前3–6个月购买",
},
"住民税(第二年起,年度一次性)": {
"金额": "约¥300,000–450,000 JPY(年薪500–600万情况下)",
"支付方式": "通常分4次(6月、8月、10月、次年1月)",
"第一年陷阱": "第一年没有住民税,第二年突然来,一定要提前存钱",
},
"在留卡更新": "约¥4,000 JPY(小额,但需要预约)",
"健康诊断(健康診断)": {
"费用": "公司通常全额负担年度健康检查",
"追加检查": "如需追加项目,自付约¥5,000–20,000",
},
"年末日本国内旅行": {
"推荐": "日本国内旅行是重要的放松和文化体验",
"费用": "4天3晚国内旅行约¥50,000–80,000(含交通住宿)",
"建议频率": "每年2–3次,纳入年度预算",
},
}
